  • 3/4 cup + 2 tablespoon whole wheat flour
  • 1/2 teaspoon kosher salt
  • 1/2 cup chocolate chip (semi-sweet or others)
  • 1/2 cup peanut butter chip
  • 2 tablespoon + 2 teaspoon cocoa powder
  • 1/4 cup + 1 tablespoon boiling water
  • 1 oz of semi-sweet chocolate chip
  • 1/4 cup + 1 tablespoon vegetable oil
  • 1 oz unsalted butter - melted
  • 1 large egg
  • 1 large egg yolk
  • 1 teaspoon pure vanilla extract
  • 1 cup + 3 tablespoon granulated sugar

For toppings:

  • 1/4 cup creamy peanut butter
  • Extra peanut butter chips


  • Preheat oven to 350°F.
  • Line an 8”x8” square baking pan with two strips of parchment paper in a cross pattern, leaving excess hanging out on all four sides. This will allow for easy removal of the brownie after baking.
  • In a small mixing bowl, add flour, salt, chocolate chips and peanut butter chips, mix with a spatula and set aside.
  • Melt butter in a small bowl in the microwave for 30 seconds.
  • In a large heat proof bowl, add cocoa powder and boiling water, whisk until cocoa powder dissolves.
  • Add 1 oz of semisweet chocolate chip to the hot cocoa powder mixture and whisk until chocolate chips melted creating a smooth chocolate mixture.
  • Add oil and melted butter and whisk until combine.
  • Add egg, egg yolk and vanilla and whisk until smooth.
  • Add sugar and whisk until completely incorporated.
  • Now add the flour and chips mixture set aside earlier, fold using a spatula until just combined. The batter does not need to be smooth, avoid overmixing.
  • Pour mixture into the prepared baking pan. Bake for 40 minutes.
  • Remove from oven and allow the entire pan to cool on a wire rack.
  • When cool enough to touch, lift the entire brownie out of the pan by lifting the parchment paper ends. Cut into 9 square portions with a serrated knife.
  • To prepare the peanut butter glaze, melt 1/4 cup of creamy peanut butter in a bowl for 30 seconds in the microwave.
  • Sprinkle a few peanut butter chips over each brownie portion and generously drizzle the melted peanut butter over the top using a small spoon.


1. Using whole wheat flour will create an extra chewy brownie which I like. But you can substitute the same amount of all-purpose flour or white whole wheat flour in this recipe.
2. I used mini semi-sweet chocolate chip in the flour mixture, but you can substitute regular size semi-sweet chips, milk chocolate chip for a sweeter taste or bittersweet chips for the opposite effect.
3. Store brownies in an airtight container on the counter for up to 5 days.
