Peanut Butter Blondies

Hey there, and welcome back, friends.

You are in for a treat!

These moist and delicious peanut butter blondies are made with Reese’s peanut butter chocolate chunks, brown butter, and chopped walnuts. 

Peanut Butter Blondies

I originally made these easy peanut butter blondies for my Pass the Cook Book Club back in 2013.

That month, the cookbook of choice was Barefoot Contessa Foolproof: Recipes You Can Trust by Ina Garten. I love Ina (who doesn’t right?) and as an avid Food Network fan, I was introduced to her early in my culinary journey. One of my earliest successful chocolate cake recipes is from Ina’s archive and it’s still my go-to for a moist chocolate cake.

So I was very excited about that month’s choice and went straight for the dessert option (duh!) on the list of three recipes (Chocolate Chunk Blondies, Easy Gazpacho & Goat Cheese Croutons & Foolproof Ribs with BBQ sauce).

Chocolate Chunk Blondies

I made the chocolate chunk blondie recipe two ways. First in its original state with chocolate chunks and it was glorious. But the second time, I adapted the recipe to include Reese’s peanut butter cups instead of chocolate chunks and because I have been on a brown butter kick lately (see brown butter week here, here, and here), I browned the butter as well to enhance the flavor.

Reese’s Peanut Butter Blondies

All I can say is, that these blondies made with Reese’s peanut butter cups are the BOMB!! They are moist, crunchy, and addicting. The loaded peanut butter chunks were a great addition and they added extra moisture to the bars. In addition, the brown butter caramelized the flavors and I loved it! You need to try them…ASAP seriously!! As always, any recipe from Ina is amazing and this book is already waiting in my cart for my next amazon order.

Peanut Butter Blondie Ingredients

To make these delicious blondies you will need a few ingredients. You will need to brown the butter, but it’s worth it because it adds so much flavor to these blondies.

  • unsalted butter
  • some light brown sugar
  • granulated sugar
  • pure vanilla extract
  • a few extra-large eggs
  • all-purpose flour
  • baking soda
  • Kosher salt
  • chopped walnuts
  • Reese’s peanut butter chocolate chunks

I suggest making sure your eggs are at room temperature because it makes a better blondie. 

If you don’t have light brown sugar you can use regular brown sugar. 

You can omit the walnuts if you don’t like them but I feel they add the perfect amount of crunch to these blondies. 

How to make Peanut Butter Blondies 

Blondies are easy to make. Start by preheating the oven to 350 degrees. Grease and flour a 9 x 11 x 2-inch baking pan.

In the bowl of an electric mixer fitted with the paddle attachment, mix the butter, brown sugar, and granulated sugar on high speed for 3 minutes, until light and fluffy.

With the mixer on low, add the vanilla. Next, add the eggs, one at a time, and mix well, scraping down the bowl after each addition.

In a small bowl, sift together the flour, baking soda, and salt.

Don’t overbake! The toothpick may have melted chocolate on it but shouldn’t have wet batter. 

Cool completely in the pan and cut into 12 bars.
