Peanut Butter Brownies

Prep Time 15 minutes
Cook Time 40 minutes
Total Time 55 minutes


  • 1 cup unsalted butter
  • ½ cup semi-sweet chocolate morsels
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tsp vanilla extract
  • ¾ cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • ½ tsp kosher salt
  • ½ tsp baking powder
  • ½ cup creamy peanut butter


    1. Preheat oven to 350°F. Line a 9-inch baking dish with parchment paper. Set aside.
    2. In a medium sized saucepan, melt butter over medium heat. Remove from heat and add in chocolate chips and sugar.
    3. Stir until chocolate is completely melted. Add in eggs, one at a time, stirring completely after each addition. Stir in vanilla.
    4. Add the cocoa powder, flour, salt, and baking powder. Using big strokes, stir in JUST until mixed and no longer see dry ingredients. DO NOT BEAT OR OVER STIR.
    5. Pour batter into dish and dollop with peanut butter. Swirl peanut butter into brownie batter with a knife.
    6. Bake for about 40-45 minutes. Remove from oven and cool completely before cutting.


  • Do not over stir after adding the dry ingredients.
  • Use a plastic knife for cutting cooled brownies. Works like a charm without ripping the brownies.
  • Avoid using natural peanut butters as they tend to have oils that make them separate from the chocolate.

  1. That frosting layer looks fantastic! I need to get a Hersey bar and dunk it in peanut butter :). That is a wonderful idea!

  2. I totally agree – how can you not love peanut butter and chocolate? Can’t wait to try this, thanks for sharing!

  3. Is this just regular milk? I looked at the buttermilk brownie recipe and it looked like this one best I could remember what it said.

    1. With this recipe I did just use regular milk instead of the buttermilk. I liked the flavor better with the peanut butter!

  4. These look absolutely unreal! The PB chips in that fudgy base and the peanut butter swirled into the frosting? You know what’s up 🙂 Pinning!

  5. I could definitely eat peanut butter and chocolate just about every day, especially it were in the form of these brownies! These look SO good! I wish I could just dig into these for breakfast!

  6. Okay, I don’t love PB and chocolate. I’m MARRIED to it, so it’s beyond love. Or, I would be married to it if I could be. My husband would understand. 🙂
    These look incredible. Like, I’m planting my face in the frosting in my head right now. Such happiness!
