Ingredients
  

Peanut Butter Dough
  • 1 cup Creamy peanut butter - Use full-fat, not natural
  • 1 cup Brown sugar - Packed
  • 1 large Egg - Room temperature
  • 1 teaspoon Vanilla extract
  • 1 pinch Salt - Balances sweetness
Brownie Dough
  • ½ cup Butter - Melted and slightly cooled
  • ¾ cup Sugar - Granulated
  • 1 large Egg - Room temperature
  • 1 teaspoon Vanilla extract
  • ½ cup All-purpose flour - Spoon and level
  • ⅓ cup Cocoa powder - Unsweetened
  • ½ teaspoon Baking powder
  • ¼ teaspoon Salt
  • ½ cup Chocolate chips - Optional, for extra richness

Equipment

  • 2 Mixing bowls (Keep peanut butter and brownie dough separate)
  • 2 Baking sheets (For batch baking)
  • 1 Parchment paper or silicone mat (Prevents sticking)
  • 1 Cookie scoop or tablespoon (To portion dough evenly)
  • 1 Wire cooling rack (Cool cookies evenly)

Method
 

  1. In a bowl, mix peanut butter, brown sugar, egg, vanilla, and salt until smooth. Set aside.
  2. Whisk melted butter and sugar until smooth. Add egg and vanilla, mix well. Stir in cocoa powder, flour, baking powder, and salt until just combined. Fold in chocolate chips.
  3. Take 1 tablespoon of each dough, press together, twist gently to marble, and roll into a ball.
  4. Arrange cookies on parchment-lined sheet, spaced 2 inches apart. Bake at 350°F (175°C) for 10–12 minutes, until edges are set but centers soft.
  5. Let cookies rest on pan for 5 minutes, then transfer to rack to cool completely.
