By Rachel
March 18, 2022

These chocolate peanut butter blondies are thick, chewy, and loaded with rich milk chocolate. Peanut butter cookie dough with mini chocolate chips, chopped Reese’s peanut butter cups, and topped with sea salt. This dough requires no chill time and the bars bake up in about 30 minutes. Perfect for birthdays or the peanut butter lovers in your life!

Tips for successful blondies:

  • Don’t overmix ingredients, only mix until incorporated.
  • Grease AND line your baking pan. I like to grease the bottom and corners really well and over line with a piece of parchment paper so I can easily lift out my blondies.
  • Allow blondies to cool completely, this helps so they don’t fall apart! Let them cool if you want nice even bars.

Tools I used for this easy recipe:

  • KitchenAid 6 Qt. Stand Mixer – I always recommend a stand mixer as it saves time and helps to keep baked goods consistent.
  • Rubber Spatula – a must for any home baker! Perfect for scrapping cookie dough out of the mixing bowl.
  • USA Pan 8″ Square Pan – another USA Pan product I love! The corners of my bars and cakes never stick and I love the squared of edges this pan creates.

Highlights of this peanut butter blondies recipe:

  • Loaded with peanut butter flavor
  • Chewy texture
  • Fudgy blondie recipe

Why use room temperature eggs in cookies and blondies?

Room temperature eggs mix together a lot easier than cold eggs, resulting in lighter, fluffier baked goods! Room temperature eggs also whip up a lot better which makes them important to use when making meringue or items that call for a lot of eggs like, angel food cake. Don’t have room temperature eggs? Set a few cold eggs out 20-30 minutes before you need them.

Grocery List:

  • All-purpose flour
  • Baking powder
  • Salt
  • Unsalted butter, softened
  • Smooth peanut butter (could substitute natural peanut butter or almond butter)
  • Light brown sugar
  • Granulated white sugar
  • Large eggs
  • Vanilla extract
  • Mini chocolate chips (or sub dark chocolate chips)
  • Reese’s peanut butter cup
  • Flaky sea salt

Instructions for the chocolate peanut butter blondies:

  • Preheat oven to 350 degrees F. Grease or line an 8″x 8″ baking pan, set aside. In a small bowl combine the flour, baking powder, and salt, stir to combine and set aside.
  • In the bowl of a hand or stand mixer fitted with a paddle attachment, cream the butter and sugars until light and fluffy, 3-4 minutes. Add in the peanut butter and mix for an additional 1-2 minutes. Add in the eggs, one at a time and the vanilla. Scrap down the sides of the bowl.
  • Slowly add the dry ingredients into the wet ingredients and mix on low speed until combined. Fold in the chopped mini chocolate chips and Reese’s peanut butter cups, transfer into the prepared baking dish. If desired, press a few whole Reese’s cups on top prior to baking.
  • Bake at 350 degrees for 25-30 minutes or until a toothpick inserted comes out clean. Remove from the oven and let cool on a wire rack, sprinkle with flaky salt and allow to cool before cutting. Keep in an airtight container for up to a week.

*You can also mix these blondies in a large mixing bowl using and electric mixer

*For an extra crunch, mix in chopped peanuts

*If you do not have an 8″x 8″ baking pan you can substitute a 9-inch pan
