Ingredients
  

For the Peanut Butter Cookie Layer:
  • 1 cup creamy peanut butter (Skippy or Jif recommended)
  • ½ cup granulated sugar
  • ½ cup light brown sugar (packed)
  • 1 large egg
For the Brownie Layer:
  • 2 ounces unsweetened baking chocolate (coarsely chopped)
  • 2 ounces semi-sweet baking chocolate (coarsely chopped)
  • ¾ cup unsalted butter (1 ½ sticks)
  • 1 ½ cup granulated sugar
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup all-purpose flour
  • ½ teaspoon salt (or to taste)

Equipment

  • Mixing bowls
  • Whisk or Electric Mixer
  • Rubber spatula
  • 9x13 inch baking pan
  • Parchment paper

Method
 

Prepare the Peanut Butter Cookie Layer:
  1. In a medium mixing bowl, combine the 1 cup of creamy peanut butter, ½ cup of granulated sugar, ½ cup of packed light brown sugar, and 1 large egg. Use a whisk or electric mixer to blend everything together until smooth and creamy. Set aside.
Make the Brownie Batter:
  1. In a microwave-safe bowl, combine the 2 ounces of unsweetened baking chocolate, 2 ounces of semi-sweet baking chocolate, and ¾ cup of unsalted butter. Microwave in 30-second intervals, stirring in between, until melted and smooth. Let it cool slightly.
  2. Once the chocolate mixture has cooled, add 1 ½ cups of granulated sugar, 3 large eggs, and 1 tablespoon of vanilla extract. Mix well until fully combined.
  3. Stir in 1 cup of all-purpose flour and ½ teaspoon of salt. Mix until just combined; don’t overmix! The batter should be thick and fudgy.
Layer the Brookies:
  1. Preheat your oven to 350°F (175°C). Grease or line your 9x13-inch baking pan with parchment paper. Pour the brownie batter into the pan and spread it evenly. Then, dollop spoonfuls of the peanut butter cookie mixture on top of the brownie layer. Use a spatula to swirl the two batters together lightly, creating a marbled effect.
Bake:
  1. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. The brookies will continue to set as they cool, so avoid overbaking.
Cool and Serve:
  1. Allow the Peanut Butter Brookies to cool in the pan for at least 15 minutes before slicing into squares. Enjoy them warm or at room temperature!

Notes

  • For extra chocolate flavor, add chocolate chips to the brownie batter.
  • Try swirling in jam for a fruity twist.
  • Store in an airtight container for up to 3 days at room temperature.
