I tend to believe that the combination of chocolate and peanut butter is a good example of the whole being greater than the sum of its parts. I do love them on their own merits individually, but the two together is just something magical.

Peanut Butter Cup Blondies combine sweet, soft, chewy blondies with everyone's favorite - peanut butter cups!

I’ve lost count of the number of recipes I have collected over the years featuring this flavor pairing. My decision to make this particular recipe was based solely on the fact that I had recently, on a whim, bought a package of miniature peanut butter cups from Trader Joe’s. It was either bake with them or slowly eat them until the shame set in.

Peanut Butter Cup Blondies are a must for peanut butter and chocolate fans!

These blondies are a breeze to make. You can go from ingredients to oven in about 20 minutes. That’s always a plus for me. And the result is just as pleasing as you’d expect with this winning ingredient combination.

Yield: 16 2-inch squares

Prep Time: 15 minutes

Cook Time: 19 minutes

  • 1 & 1/4 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/3 cup creamy peanut butter
  • 1/4 cup butter, melted and slightly cooled
  • 2 tablespoons milk
  • 1 teaspoon vanilla extract
  • 2 large eggs, lightly beaten
  • 1/4 cup semisweet chocolate chips
  • 0.75 ounces peanut butter cups (about 4 regular size) chopped

Directions:

  1. Preheat oven to 350°. Coat a 9-inch square baking pan lightly with cooking spray.
  2. Combine flour, sugar, baking powder, and salt. Set aside.
  3. In a separate bowl, combine peanut butter, melted butter, milk, vanilla extract, and eggs. Stir well.
  4. Add peanut butter mixture to flour mixture, stirring until combined. Stir in chocolate chips.
  5. Transfer batter into baking pan. Arrange the peanut butter cups over the batter.
  6. Bake for 19 minutes, or until a wooden pick inserted into the center comes out with moist crumbs. Cool in pan on wire rack.

  1. These look amazing! Chocolate and peanut butter are the most reliable ingredient buddies.

  2. Trader Joe’s mini peanut butter cups……I also bought a container of those last week and have been trying to find a good recipe in which to incorporate them! I think this is it. Your photos make them appear delicious and so decadent and then on the top of your printed recipe it says the recipe is from “Cooking Light”. How can that be? These sound anything but light! And not that I don’t believe in trying to eat healthier and cut calories, but when I personally bake, I’m more like Paula Deen – the more butter the better! I like to bake FULL fat. Do these PB Blondies taste light?

    I also love the fact that they are so easy to throw together. That definitely is an incentive.

    Thanks for the recipe.

  3. Perfect! Thank you.

  4. Heidi, these didn’t taste light to me. You sound like my kind of baker!

  5. chocolate and peanut butter is an amazing combination. I will be making these for sure!

  8. Just the thought of a peanut butter cup in each bite of a blondie makes me so hungry

  9. These look absolutely scrumptious. You are so right that chocolate and peanut butter together are better than the sum of its parts. Have you ever tried Trader Joe’s dark chocolate peanut butter cups? Those are my favorite. I don’t believe they come in mini, though, so you’d have to cut them up for baking. Anyway, thanks for the great recipe.

  10. I love those new mini Reeses cups, hadn’t thought yet beyond eating them plain…great idea here!

  11. i love the idea of baking my fave trader joe’s candies…

  12. These are cooling as we speak! They look fantastic! I am wondering how they cut though, I’m wanting to use a heart shaped cookie cutter instead of the typical square. Will they crumble? I don’t want to mess them up, since I’m taking them to a party! Love your blog, the photography makes me drool!

    • Hi, Jordan. These weren’t terribly crumbly, but I’m not sure they’d stand up to a cookie cutter. You might try refrigerating them for a bit before you cut them. That might make them firm enough. Good luck and enjoy!

  13. These look absolutely delectable! Peanut butter and chocolate is always a good combination. Can’t wait to try them out! Thanks!

  14. Yes Please!! I will be trying them out this weekend ๐Ÿ˜‰ Always looking for new ways to bring peanut butter and chocolate together…this definitely is a welcome twist on peanut butter chips in regular brownies ๐Ÿ™‚
