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?

These Peanut Butter Blondies Are a Forever Favorite:

Soft & ultra-chewy, and packed with crispy Reese’s Pieces Only 1 bowl needed No mixer required (just like these soft-baked M&M Cookie Bars) Super simple from start to finish. Prepare and bake the blondies in less than an hour. The hardest part is waiting for them to cool! A year-round favorite welcome at Halloween parties, summer BBQs, Christmas celebrations, and spring picnics Convenient for cutting, stacking, and transporting

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?

Ingredients to Use & Why

Easy 1-Bowl, No-Mixer, No-Chill Recipe

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. From my kitchen to yours, I hope you enjoy this very special recipe; it was the first recipe ever published on my website and I’ve gone back to re-photograph and republish it some years later. It began a delicious career and introduced me to so many sweet readers from around the world. Thank you, from the bottom of my peanut butter-loving heart, for making and trusting my recipes. Whether you’ve been following since the beginning or joined along over the years, thank you for being here. Let me know if you give these blondies a try!
