Ingredients

Scale

Brownie Batter

  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 cup all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking powder

Peanut Butter Swirl

  • 3/4 cup smooth peanut butter
  • 1/4 cup powdered sugar
  • 2 tablespoons milk

Instructions

  1. Prepare Brownie Batter: In a large mixing bowl, combine melted butter and granulated sugar and whisk together until well blended. Add eggs one at a time, beating well after each addition. Stir in vanilla extract. In a separate bowl, sift together flour, cocoa powder, salt, and baking powder. Gradually fold the dry ingredients into the wet mixture until a smooth brownie batter forms.
  2. Make Peanut Butter Swirl: In a small bowl, mix the peanut butter with powdered sugar and milk until creamy and smooth. If needed, adjust with extra milk or powdered sugar to reach a swirlable consistency.
  3. Assemble Swirl Cookies: Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper. Drop spoonfuls of brownie batter onto the baking sheet. Dollop the peanut butter mixture on top of each brownie batter mound. Using a toothpick or skewer, gently swirl the peanut butter into the brownie batter to create a marbled effect, being careful not to overmix.
  4. Bake Cookies: Bake in the preheated oven for 12 to 15 minutes, or until the edges are set and the centers appear slightly underbaked for a fudgy texture. Remove from oven and allow to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

  • For best results, use room temperature eggs to ensure smooth batter.
  • Do not over-swirl the peanut butter or the marbled look will be lost.
  • These cookies are best enjoyed within 3 days but can be stored in an airtight container at room temperature.
  • To enhance the peanut flavor, consider adding a pinch of salt to the peanut butter swirl.
