    Why you'll love Peanut Butter Cup Brownies

    The marriage of chocolate and peanut butter has been a delicious one for decades. Now we've taken those flavors to the next level by adding the candy to your favorite brownie mix.

    The result is one seriously ooey-gooey heavenly treat. Be sure to grab a big glass of ice cold milk.

    Recipe Ingredients

    Ingredient image labeled with text for the needed items for the recipe.

    Brownie mix — any mix will do. We're a fan of Pillsbury so that's what we used.

    Peanut butter cups — Reese's peanut butter cups were the only brand we considered and opted for the mini's.

    Baking needs — Boxed brownie mix require eggs, water, and oil. Consult your specific box for the precise quantities, as they all vary.

    Be sure to scroll down to the full recipe card for the complete list of ingredients along with their quantities. 

    Additions

    For a more intensely delicious brownie experience, you could add some of the following with the mini peanut butter cups:

    • Peanut butter chips
    • Chocolate chips.
    • Dragees like M&M's or Reese's Pieces
    • Creamy peanut butter

    How to make peanut butter brownies

    Brownie batter mixed in a pink bowl with a wooden spoon.

    Step 1 — Preheat an oven to 350°F. Halve the mini peanut butter cups. Spray the cast iron skillet with cooking spray. Make the brownie batter per package directions.

    The brownie batter being poured into a prepared pan.

    Step 2 — Pour enough brownie batter into the prepared skillet to cover the bottom.

    Mini peanut butter cup candy cut in have and placed into the brownie batter.

    Step 3 — Press the candy halves into the brownie batter, fitting in as many as you can in any desired array.

    The remaining brownie batter being poured into the skillet to cover the candy.

    Step 4 — Pour the remaining brownie batter over the peanut butter cups. Bake according to the time indicated on the package.

    Recipe FAQs

    Can I use applesauce instead of oil?

    Yes you can.

    Can I use a mixer to make the brownie batter?

    Technically yes, but we recommend mixing the batter by hand. Clumps are good, you don't want a smooth batter.

    Can I make homemade brownie batter?

    Yes, absolutely.

    How long will leftover brownies last?

    Store the completely cooled peanut butter brownies in an air tight container for up to 4 days.
