Creamy Lemon Crumb Bars with a quick oatmeal crumb base and a sweet, tart filling that is a cross between lemon curd and lemon cheesecake.
Spring is the perfect time for fruity Desserts like these Creamy Lemon Crumb Bars. They are right at home with other popular favorites such as Cherry Coconut Bars, Apricot Shortbread Bars, and Key Lime Cheesecake Bars.
These Creamy Lemon Crumb Bars taste like a cross between a lemon curd bar and a lemon cheesecake bar sandwiched between the softest oatmeal cookie you’ve ever made. Take into account how easy they are to make and how bright these flavors are, and these bars will make you feel like Spring has arrived.
Lemon Bars have long been a classic favorite dessert to make, and lemon tarts are actually a most requested dessert by a pretty far margin. The rich filling is both easy and impressive and even though these bars aren’t going to win any sort of a beauty contest, you will think the flavor is out of this world.
If you have time, you can also try them frozen. You’ll love putting these bars in the freezer to enjoy cold and to keep if you have any left over. Another tasty and beautiful option is to dust the top with coarse sanding sugar before baking for an extra crunch. They make the bars look like jewels!

Frequently Asked Questions
Try using dried cherries or dried blueberries in the bars. You can make them even better by soaking them in more lemon juice or water. Add sliced freeze dried strawberries on top of the filling and before the crumble for strawberry lemon bars.
Absolutely! Use half lemon juice/zest and half lime… or even ALL lime!
Any type of lemon will work for these bars, but if you use Meyer Lemons, they are AMAZING. Meyer Lemons are slightly sweeter and very juicy, making them perfect for baking recipes.
Dip the bottoms of these bars in melted white chocolate for an even more over the top experience.

I have been begged to make this recipe at home and at work again and again. Excellent!
These are AMAZING! I followed the recipe exactly as presented and while I was seriously tempted to have one last night, I did end up freezing them and slicing them perfectly 24 hours later. Thank you.
Great recipe. Only thing I did was add about 4 oz cream cheese (I put it in everything I can). Very good recipe.
This is a favorite every time I make it. Thank you!
I made these for the first time the other day. Just to give you an idea of how good they are…after I tried the first one, I just wanted to take the entire pan, sit myself on the couch and finish them off. I’m a seasoned cook and baker, and I can tell you these are “to die for”. Even my boyfriend, who is not a fan of lemon-flavored desserts, enjoyed them immensely.
Can these be frozen for a later date to save time.
I am making my fiancé a nice dinner tonight and wanted to include these. They are still in the oven but this is one of the only times I am confident this is going to be amazing. I can’t wait to try them
These are SO GOOD! My best friend just had her first baby and I made a few freezer dinners to take to her and thought I’d throw in a sweet treat, too. She loves lemon desserts and I stumbled across this recipe. After cutting them up, I snuck one (you know, for quality control) and I am amazed! The filling has so much lemon flavor and is perfectly tart without being too tart. The oatmeal crust and crumb topping are a perfect balance for the creamy lemon filling. It was hard not to eat a second one, and I will have to make another batch to stay home, since this one is going to my friend!
Making these…again…EXCELLENT squares! LOTS of lemon flavour, which we love. And very easy to make. Definitely recommend to anyone who loves lemon!
These lemon bars are so delicious. I made them twice in one week.
I have been trying to eat more gluten free things, as well I have friends who are gluten free so I tried to make them using the gluten free oats and flour. A delicious gluten free option as well.
Just had a friend request the recipe.
Hi Hannah – Do I substitute equal amounts of GF flour and oats? Thanks Lisa
I made these a few months back and truly have never loved a dessert this much! I find it hard to find lemon bar recipes that have the right amount of tart and this one for sure is the perfect blend of tart and sweet. I’m making them again today and will have this in my regular rotation! Thank you for sharing!
Oh my sweet goodness these are delicious. I’ve never rated a recipe before but I was inspired by these yummy bars. Followed the recipe word for word. Pure perfection!
Best lemon bars I’ve ever had! 🙂
Can I use steel cut oats instead of rolled oats?
Absolutely delicious! I always double the recipe so I can keep some before sharing the rest. It is a crowd pleaser. I am so glad I came across this. Thank you for sharing!
How do you adjust the two baking times when doubling the recipe in a 13×9 pan? Thanks!
Honestly this is the nicest slice I’ve ever eaten.
I don’t bake a lot but both times I’ve made it, it’s turned out perfectly. An absolute winner!
Loved these! I added a bit more lemon juice because I just love the tartness. Recipe came out great– we tried fresh out of the oven and after it was refrigerated. It was a bit easier after being chilled to cut and eat but great either way. I am going to make these again and again.
Fantastic, Savannah! I’m so glad they worked out for you.
I made these for Valentines day and my hubby LOVED them!!
I’m so glad they were a hit, Patsy.
Hi. This looks delicious. Can I double the recipe?
Of course! Enjoy!
These were delicious. I made them exactly as recipe described and they came out perfect. Delicious lemon bar with an oatmeal cookie base and crumb like topping. So good!
Delicious, but how to you keep the filling from soaking into the crumble? I followed the recipe, but since the filling is a thin liquid, the “topping” just mixes in with it and it all combines together. I was really hoping for the layered effect, so it was disappointing.
I’m so sorry this comment got stuck and I just came across it. I know your dessert is long gone now, but it shouldn’t be very thin after baking the filling. Perhaps the filling needed to bake longer? The crumble should stay atop it without sinking directly to the bottom.
This recipe is sooo good! But for those counting calories, the count is way off. So do your own math.
follow up for the cookie idea?
the 5 stars are for the orig recipe
cookie idea maybe a 3 1/2-4 stars
need that yummy lemon filling to set off the oatmeal goodness ???
i’m trying just the crust for some yummy cookies!!
baking now will be back with critique?
This is the best Oatmeal Lemon bar recipe I have tried. The additional butter, flour and oats makes a generous batch and baking the bottom portion first really makes the crust so tasty. The egg yolks in the lemon mixture are a nice addition to make it more fluffy. I only used one yolk and plenty of lemon juice and zest. These are so delicious, they are hard to stop eating!
I love lemon flavored desserts, and I’ve tried quite a few traditional lemon bar recipes but they’ve always been a little off balance (too sweet, too tart, not enough crust ect) for my tastes. I had almost given up finding one I really liked.
This one was PERFECT! The double crust and the lemon paired with the sweetened condensed milk really makes a nice and balanced dessert that’s just sweet, tart, and crunchy enough. I also found the filling to be firmer than the kind made with just eggs and lemon, and coupled with the double crust it made the bars much easier to cut and eat without them falling apart.
I think if I were to try my hand at traditional lemon bars again I might actually use this crust, since it both tastes better and supports the filling more/doesn’t fall apart as easily.
These became an instant hit in my house, and I can’t wait to make them again. Thanks for the recipe!
You’re welcome, Sunny!
These are amazing!! First time trying them and they are seriously SO good. My family all loved, kids included. I made with gluten free flour for an interolance and no one knew. These remind me of a crisp, but with lemon instead of berries or apples. The oatmeal base and topping is so good!
This recipe is perfect ?. I’ve made it twice in one week!
Woohoo! Thanks for the 5 stars, Shawna.
Someone really special to me made these for me, And I ate the whole pan. I’m not even mad about it.
Hooray! Yeah, these are a favorite of mine too. Glad you enjoyed them.
Can we use quick oats instead of rolled oats?
Quick oats offer a softer, moister finished product so the texture might be different though it will still be delicious! Good luck!
I’m not a huge lemon flavor fan but holy moly these are freaking DELICIOUS!!!! I think in one week I made them three times. When I was out of fresh lemon juice I also used bottled store bought lemon juice but prefer fresh of course!
Yay!! I’m so glad you’re loving the recipe. Thanks for the 5 stars.
I would give it 5 but , once again I followed directions and cooked that bottom layer for 15 min. Only cook 5 or it is impossible to get from the bottom of the pan. The rest is the best lemon bar recipe I have had. And don’t press it down hard. Just a light Pat for crust.
If you dip the bottom of pan in a sink of hot water, you can get it out of the pan! These are absolutely delicious! Everybody loves them!
How do you think the filling would turn out if you used a mix of sweetened and unsweetened condensed milk? I would prefer it tart over very sweet, but would that ruin the recipe?
I’ve not tested it before but if you decide to try, I’d love to know how it turns out. Good luck!
These are delicious! I’ve made 2x now. I crave the creamy, lemony and crumbly goodness! Highly recommend. I’ve made a full and low fat/sugar substitutes version and both turned out well. I think the key is fresh lemon. Great recipe.
Thanks for the 5 stars, Shannon.
Can i freeze these lemon bars?
It can be tricky but make sure to double wrap the bars in freezer-safe plastic wrap then place them in a freezer safe plastic bag, squeezing all the extra air out before the final seal. They should last up to 6 months is stored properly.
This lemon bar was a huge hit at work! It was so creamy and rich. I love the crust and actually used the recipe for a pie and it worked pretty well. I am thinking to omit the sugar and use it to make a quiche crust next. I feel that the crust is semi healthier compared to regular pie crust (just a little). The oats create good crunchiness. I will definitely make this bar again. Thank you for the great recipe!
I’m so glad you love the recipe so much, Kate.
Made these for a baby shower brunch – mom-to-be wanted something lemony, and I wanted to make something a bit heartier than a dessert, but still elegant. These oatmeal cream lemon bars (I had some freeze-dried raspberries, so I added those) were a perfect fit! Can’t wait to make them again.
Happy to hear they were a part of such a special event! Thanks for sharing!
These bars are wonderful! That delicious lemony filling is so perfect with the yummy oatmeal crumble. Will definitely be making these again. Thanks for this great recipe!
You’re welcome Carol.
Only one word for them…….INCREDIBLE:)
Thanks for dropping by to let me know! I’m so glad you enjoyed it!
This is so good! I even made it with regular salted butter. I’m a pretty traditional lemon square girl…I was a little skeptical of the oatmeal…so freaking good! I can’t say one thing bad about this recipe…amazing!

Oh Sabrina, my mouth is watering as I look at the photo of your “Creamy Lemon Crumb Bars”! They’re quick to make, sound delicious, and I have all of the ingredients on hand, so I’ll be making these bars later this afternoon. I have no doubt that we’ll enjoy them for dessert this evening.
Thank you so much, Angelina.
Loved this recipe! I received so many compliments about this square. New subscriber here, thank you.
Yay! I’m so glad everyone loves them. I look forward to seeing you around the site.
Hi, I made these lemon bars a while ago, they tasted very nice. I love the lemon flavour, but my crust was very hard. Can you please let me know where I went wrong with the crust because I’d really like to make them again very soon.
So glad you enjoyed them. Did you change any of the ingredients in the recipe? If you’d like you can email me at contact @ dinnerthendessert .com and we can troubleshoot together.
I have made these bars a few times now following the recipe exact and they are absolutley amazing! Very easy and very good!! 2 thumbs up and 5 stars!
Thanks for coming back to let me know, Stacey!
I used half lemon and half lime since I only had one lemon. They were really good, but cloyingly sweet so we only ate small bits at a time and some went to waste. The crust was especially good as It was really chewy. I’d take to a gathering, but it was a bit much just for my little family.
I made the lemon bars today. I thought the recipe was well written and they turned out perfectly. Thanks for a great recipe!
I made the lemon bars today. I thought the recipe was well written and they turned out perfectly. Thanks for a great recipe!
Sooo good!, I’ve made them three times now ,
Great, easy dessert. My whole family and coworkers loved it. We loved the oatmeal crumble!
You used old fashion oats and not quick oats right?
Thank you in advance!
Yes, old fashioned rolled oats. 🙂 Enjoy!
Can I use quick cooking oats? Thanks.
They’re a more delicate texture than old fashioned oats so I’m not sure if the crust will hold up as well.
What can I substitute for sweetened condensed milk. I usually use can coconut milk and 3/4 sugar or can I leave it out
You don’t want to leave it out. I haven’t tested this recipe with a substitute for it but if that’s what you usually use as a substitute, you could try it. I’d love to know how it turns out if you decide to try.
Can “quick-1 minute” oats be substituted for the rolled oats?
Quick oats have been processed and are slightly softer than rolled oats but should work as a substitute. I haven’t test it though and would love to know how they turn out if you decide to use them.
Hi! New to baking…. if I need to freeze some squares, what is the best method? Individually or several in zip bags or….? They are very good!
I would suggest freezing individually. They tend to stay better that way. I’m so glad you enjoyed them.
I made these for my wedding reception and they were a huge hit! My step daughter even asked for me to make them for Thanksgiving this year. I found that buying lemons by the bag is much cheaper than individually.
I’m so glad you guys enjoyed it! Thanks for coming back to let me know!
These are 244 calories when you serve 16 like I did. 🙂
Love it! Thanks
How much flour?
1 1/4 cups of flour 🙂 Enjoy!!
Can you use fresh berries instead of dried or are they add too much liquid?
I’d stick with dried but if you want to try fresh, just give them a good toss in flour first. Let me know how they turn out!
Are these curable if made cold and will they stay in one piece for a bake sale?
Yes, these bars are able to be cut and would be wonderful for a bake sale….I’d buy one 🙂 If you think it’ll be warmer where you’ll be for the sale, I might suggest keeping the cool or individually wrapping them to keep them perfect.
I wasn’t crazy about these. They were way too greasy and the condensed milk took away from the lemon taste. I think I’ll stick with y original lemon bars.
These sound absolutely amazing. I love anything with lemon and the crust sounds delish. Can’t wait to try these out.
Thanks Danielle! You’ll have to let me know what you think 🙂
These look great! How would you scale them up to large (13 x 18) pan?
Sorry this comment took so long to get to, it ended up in my spam filter somehow! Double the recipe and it would work great in a 9×13 🙂
They are in the oven as I’m writing this. I am a bit confused though, because the recipe says at the top that the bake time is 25 minutes, but in the directions you say to bake the crust for 15 minutes, then add the filling and the rest of the topping, and bake for another 22-25 minutes. Should total bake time be 37-40 minutes or am I not reading this correctly? Thank you!
Re: Creamy Lemon Crumb Bars
Yes sorry, the widget for the recipes has been acting up with cook times listing. It is done in two parts for a total of ~37-40 minutes. I fixed it in the recipe card.
I just made these and they are divine! I love your suggestions too! I’m thinking next time I’ll try strawberries too”
It always makes me happy to hear my readers made one of my dishes and enjoyed it! Thanks for coming back to let me know!
Hi. How long would these keep in the refrigerator? I’m making them on a Friday to serve on the following Sunday.
Yikes, I’m sorry this ended up in the spam filter for some reason. Covered and in the fridge I’ve had them taste awesome for up to a week.
I absolutely love lemon bars and this recipe looks tasty! I have to add it to my easter must have baking!
Thanks, Amanda! I hope you enjoy them!
Mmmm, anything lemon… I am in. This looks so simple to make too. Bookmarking!
Thanks, Nancy! We love lemon too!
I”ve got a stash of lemons from my dad’s tree. These sound like just teething to put them to good use.
I got these lemons from a friend’s tree! They’re so much better than store bought!
Oh my, those look so good! They would not last long in my house.
They didn’t last long here either 🙂 and thanks!
I love a good lemon bar! These are intriguing as they combine my love of lemon with cheesecake. Yum!
I love lemon bars so I bet these would be something that I would enjoy making and eating right up! Thanks for sharing!
These look fantastic! I totally want to make these.
Ok. My mouth is seriously drooling! The pictures are beautiful, and I could definitely dive into these lemon bars! Thank you so much!
Aww how sweet, thank you Jeni!
Lemon is my favorite flavor for baked treats. I really have got to try these ASAP! I just need lemons to go on sale. They are so pricey here all of a sudden!
I lucked out and got a giant basketful from a friend’s tree but I totally agree with you on pricing!
