BLACKBERRY CRUMB BARS

Like these Creamy Lemon Crumb Bars, this is a great recipe for bakery treats made at home. These Blackberry Crumb Bars are just as delicious and simple to make with a pastry crust made from common ingredients that doubles at the crumb topping. The fresh blackberry filling is perfect for summer time when berries are super ripe and can be found everywhere cheap.

Blackberry Crumb Bars are one of the easiest breakfast recipes. No need for a stand mixer, adding ingredients slowly, or even softening butter. The dough for Blackberry Crumb Bars is made in a food processor and the crumbly dough is also the top layer. If you don’t have a food processor, do this by hand with a pastry cutter, forks, or butter knives, like you would a pie crust.

This recipe for Blackberry Crumb Bars has a slightly sweet crust to allow the natural sweetness of the fresh berries to come through. The crust is soft and light, but thick enough that these bars can be eaten by hand. It’s could be compared to a cross between a cake and pie crust, which makes it perfect for fresh fruit fillings!

Even though fresh blackberries can be found all year round, they are about twice as much when they are out of season. They also tend to be more tart and less juicy. If you want to make Blackberry Crumb Bars when they are not in season, use frozen blackberries. Frozen fruits and vegetables are picked at the peak of their season you won’t sacrifice taste.

If you are using frozen blackberries, thaw and drain thoroughly and pat dry. You don’t want too much liquid or your bars will get really gooey. You can use canned blackberry pie filling but don’t add the sugar. You still want to add the lemon juice and cornstarch to bring out the flavor and thicken the canned filling.

Blackberry Crumb Bars are great for summer cookouts, picnics, and potlucks. They are pie-cakes people can eat with their hands and they last for days at room temperature, so no need to worry about them getting too warm. For a tasty summer dessert at home, top warm bars with a Vanilla Ice Cream or Whipped Cream like you would with pie!

VARIATIONS ON BLACKBERRY CRUMB BARS

  • Fruit: Use seasonal fruit all year round in Blackberry Crumb Bars. Peaches, plums, or this Apple Pie Filling would taste delicious. For bananas, slice and toss in cinnamon sugar.
  • Berries: Any fresh berries can be used in these bars like strawberries, blueberries, or mulberries. Make a Mixed Berry Crumb Bars by substituting 1 cup of another berry.
  • Crumble:  Add crunch to the crumb topping with a ¼ cup rolled oats or chopped pecans after you have pressed the crust into the baking pan. You can sprinkle extra sugar over the crumb topping too for more sweetness.
  • Muffins: Press the crust mixture into a lined or well greased muffin tin. Divide the blackberry filling evenly among muffin cups and top with crumble topping. Bake for 22-26 minutes at 375 degrees, or until cooked through and golden brown.

  1. There are the Bomb!!! I doubled the recipe-which made a little more dough than needed but it was tasty too!!! They were easy to make & so tasty… I took some to friends & received this text “OMG! These blackberry bars are absolutely amazing! Thank you soooo much!”
    Thank you for sharing your awesome recipe!!

  2. I made these with a gluten free flour blend for the 4th of July–they were great. I took one liberty: the dough seemed dry after pulsing, so I added the whole egg, and it seemed just right. This was a big hit with my family, and I will repeat it because I have quite a few handpicked bags of blackberries in my freezer.

  3. Easy and delicious! This was the perfect thing to do with some blackberries my sister in law gave me from her garden. YUM!

    1. It’s listed in the first step, 8×8 pan.

      I realize this comment is very old, so I am so sorry for the delay in replying.

  4. Sabrina, These look delicious! If I wanted to make these for a crowd, in a half sheet pan, would I double or triple the recipe? I’m looking forward to post pandemic family parties, and 8 x 8 won’t be nearly enough. I can’t wait to try them!! Thank you!

    1. I am so sorry, I am just seeing this tonight. I am sure the recipe has long been cooked/or not but I still want to try to help.

      Yes! double in a 9×13 pan! Half sheet pan could be tough because of the height of the wall of the pan. How tall is your pan?

        1. Yes, you can double the recipe. For a 9×13 pan, it will take a bit longer to cook, I would just keep an eye on it.

    2. Excellent recipe! I go berry picking often in the summer and this recipe is great. The first time I made it I didn’t have enough blackberries so I mixed in fresh blueberries and it was delicious. We like crunchy toppings so I mixed pecans and oats (total a little over 1/4 cup) the 2nd time and that came out great. So easy to make.

  5. I picked way too many blackberries last weekend and now I’m trying different recipes. Loved this recipe, Sabrina. Just the right size. My first attempt with a different recipe resulted in a very juicy version that required a spoon. And ice cream. Tasted great but not what I was going for. Your recipe made it to the family boat (none came back). The bars held together for easy serving. Thanks!
