Ingredients

Scale
  • For the Cookie Cake:
  • 1/2 cup unsalted butter (1 stick), melted
  • 1/2 cup light brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsweetened dark cocoa powder (Hershey’s Special Dark recommended)
  • 1 cup all-purpose flour
  • 1 cup white chocolate chips
  • For the Oreo Cream Cheese Frosting:
  • 1/2 cup unsalted butter, softened
  • 4 oz cream cheese, cold
  • 2 1/2 cups powdered sugar
  • Pinch of salt
  • 2 tsp clear vanilla extract
  • 1/4 cup crushed mini Oreos (about 15)
  • For Decorating:
  • 24 mini Oreos (for topping)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line an 11-inch round cookie cake pan with parchment paper.
  2. In a bowl, combine melted butter with brown sugar and granulated sugar. Stir with a wooden spoon until blended.
  3. Add egg and vanilla extract, then stir in baking soda and salt.
  4. Mix in cocoa powder and flour until fully incorporated. Fold in white chocolate chips.
  5. Spread dough evenly into the prepared pan and smooth the top.
  6. Bake for 12–14 minutes, until the cookie cake is just set and slightly rippled. Do not overbake.
  7. Cool completely in the pan before decorating.
  8. To make the frosting, beat softened butter, cream cheese, vanilla, and salt on high speed for 1–2 minutes.
  9. Slowly add powdered sugar on low speed, then beat on high until light and fluffy.
  10. Fold in crushed mini Oreos.
  11. Using a piping bag with a star tip, pipe the frosting around the cooled cookie cake edge. Top with mini Oreos while frosting is still soft.

Notes

  • Do not overbake to keep the cookie cake soft and chewy in the center.
  • Let the cookie cool fully before adding frosting to prevent melting.
  • For cleaner slices, chill the cookie cake slightly before cutting.
