Ingredients

Scale
  • 1 cup (125g) all-purpose flour
  • ½ cup (100g) granulated sugar
  • ¼ cup (25g) unsweetened cocoa powder
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup (115g) unsalted butter, melted and cooled
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup (240g) cream cheese, softened
  • ½ cup (60g) powdered sugar, sifted
  • 1 teaspoon peppermint extract
  • Green food coloring (optional)
  • ½ cup (90g) semi-sweet chocolate chips
  • 1 tablespoon heavy cream

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving overhang for easy removal.
  2. In a medium bowl, whisk together flour, sugar, cocoa powder, baking powder, and salt until combined.
  3. Add melted butter, egg, and vanilla extract to dry ingredients. Stir gently until just combined; batter will be thick and fudgy.
  4. Spread two-thirds of the batter evenly into the prepared pan to form the chocolate base. Set remaining batter aside.
  5. In a separate bowl, beat softened cream cheese with powdered sugar and peppermint extract until smooth. Add green food coloring if desired.
  6. Spread the mint mixture evenly over the chocolate base.
  7. Drop spoonfuls of the remaining chocolate batter over the mint layer. Use a knife or skewer to gently swirl the chocolate into the mint layer for a marbled effect.
  8. Bake for 25–30 minutes until edges are set and center is slightly soft but not jiggly. A toothpick inserted into the chocolate base should come out with moist crumbs but no raw batter.
  9. Cool completely in the pan on a wire rack.
  10. Melt chocolate chips with heavy cream in 20-second intervals in the microwave or use a double boiler, stirring until smooth and glossy.
  11. Pour melted chocolate over cooled bars and spread evenly. Let set at room temperature or refrigerate for 15 minutes for a firmer finish.
  12. Lift bars out using parchment overhang and cut into 16 squares.

Notes

Ensure cream cheese is softened before mixing to avoid lumps in the mint layer. Do not overmix the batter to keep a fudgy texture. Cool bars completely before adding chocolate topping to prevent melting. Bars can be made gluten-free by substituting all-purpose flour with gluten-free baking flour and dairy-free by using vegan alternatives.
