Pumpkin Fluffernutter Bars are the perfect mix of peanut butter brownie, marshmallow filling and all things pumpkin and fall flavored. Best back to school snack ever.
Pumpkin Fluffernutter Bars are the perfect bar for the rapidly arriving fall season and the beginning of ALL THINGS PUMPKIN on the blog. These bars are gooey, pumpkiny (hey, on this blog that’s a word autcorrect) and perfectly peanut buttery. Plus they’re made with Pumpkin Spice Peanut Butter from Peanut Butter and Co. who so generously sponsored this post.
Peanut Butter and Co. was founded in 1998 and while their website is ilovepeanutbutter.com they should’ve made it we’repeanutbuttermagicians.com because they have the most amazing flavors of peanut butter you will ever eat. Our personal favorite is White Chocolate Wonderful, but this Pumpkin Spice Peanut Butter is their most popular flavor and it sells out every year. So get your orders in early and go to your local grocery stores now!
I talk a lot on the blog about ingredients, good swaps and when you want to use specific products so it seems only fair we would discuss what makes Peanut Butter and Co. so special. From their site:
Peanut Butter & Co.’s line of Non-GMO Project Verified peanut butter contains no hydrogenated oils, no cholesterol, no trans-fats and, no high fructose corn syrup. Our flavors are gluten-free, vegan (except for The Bee’s Knees which is vegetarian), and certified kosher. Lastly, but just as importantly, we only use USA-grown peanuts in our peanut butter.
Also, the Pumpkin Spice Peanut Butter has actual pumpkin in it.
So of course all that delicious natural goodness needs to get mixed with homemade marshmallow fluff and baked into delicious Pumpkin Fluffernutter Bars.
I use a recipe for homemade marshmallow fluff in this recipe but you can swap for premade and these bars can be made in no time at all. Plus with the pumpkin spice flavor built into the peanut butter you’ll LOVE how easy these bars are.

TO MAKE THE MARSHMALLOW FLUFF:
In a saucepan add the water, sugar and corn syrup and over medium high heat cook until it reaches 240 degrees (about 10-12 minutes).
In a stand mixer add the egg whites until they start to foam, then add in the cream of tartar and salt and beat to soft peaks (the very top of the peak falls).
When the egg whites are ready and the sugar reaches 240 degrees turn off the heat and wait 30 seconds.
Add the sugar to the stand mixer while it is running on high speed in a very thin stream.
Beat on high heat for 5-6 minutes until the bowl is no longer warm at all.
Refrigerate until you’re ready to make the bars.

Add in the peanut butter and beat until combined.

Scoop the marshmallow fluff randomly across the pan in large dollops.
Spread small clusters of the remaining batter in between the dollops of marshmallow fluff.

If you don't want to make your own marshmallow fluff you can substitute with one canister of pre-made marshmallow fluff. The recipe above makes 2 cups.
