Soft, ultra-chewy, and packed with flavor, these peanut butter blondies will be your new go-to dessert to impress even the biggest peanut butter fanatics.

If you’ve poked around my site before, it’s no secret that I adore peanut butter treats. I make peanut butter blossoms year-round (who said they can only be enjoyed as Christmas cookies?), I’ve used these peanut butter cookies as inspiration for 8+ other cookie recipes, and this chocolate peanut butter cake is one of the most decadent beauties to come out of my kitchen.
So it will come as no surprise that my first-ever recipe published on my site in 2011 showcased… peanut butter!
These peanut butter blondies are an ode to the recipe that started it all, a reader and personal favorite that now includes even more Reese’s Pieces. Because who doesn’t love even MORE ways to incorporate peanut butter flavor into every bite?
Let me show you how easy this is.
You need a 9×13-inch pan, mixing bowl, whisk and spatula, a few staple baking ingredients, plus some Reese’s Pieces candy (or M&Ms). Did I already mention how EASY these are?
After the thick batter comes together in your mixing bowl, fold in the Reese’s Pieces, spread into your prepared 9×13-inch baking pan, and sprinkle some extra candies on top for good measure. Pop them in the oven and they’re done in half an hour. (Well, except for the hard part… waiting for them to cool.)
The next time you need an easy-to-make crowd-pleasing dessert, or just have a mega peanut butter craving, reach for this recipe.
