Ingredients

Layer 1: The Brownie Base

  • 120 g Unsalted butter softened
  • 150 g White sugar
  • 50 g Brown sugar
  • 2 Large eggs
  • 2 tbsp Vanilla extract
  • 150 g Dark chocolate melted (60g for the batter, plus extra for chunks)
  • 60 g All-purpose flour
  • 40 g Cocoa powder
  • 1/2 tsp Baking powder
  • Pinch of salt
  • Layer 2: The Middle
  • 1-2 Packs of Oreo cookies approx. 16–20 cookies
  • Layer 3: The Cookie Dough
  • 80 g Unsalted butter softened
  • 100 g Brown sugar
  • 1 Large egg
  • 1 tsp Vanilla extract
  • 120 g All-purpose flour
  • 1/2 tsp Baking powder
  • Pinch of salt
  • 1/2 cup Chocolate chips

Instructions
 

  • Prep: Preheat oven to 180°C and line an 8x8 inch square pan with parchment paper.
  • Brownie Layer: Cream the butter and sugars. Add eggs and vanilla, then stir in the melted chocolate. Fold in the flour, cocoa, baking powder, and salt. Spread evenly into the pan.
  • Oreo Layer: Place a single layer of Oreos directly on top of the brownie batter, pressing them in slightly.
  • Cookie Layer: In a separate bowl, cream butter and brown sugar. Add egg and vanilla. Fold in flour, baking powder, salt, and chocolate chips.
  • Assemble: Drop spoonfuls of cookie dough over the Oreos and gently flatten them to cover the gaps.
  • Bake: Bake for 40–45 minutes until the cookie top is golden.
  • Cool: Let cool completely in the pan before lifting out and slicing into squares.

Notes

Measuring: Use a kitchen scale for the best results; brookies are very sensitive to flour ratios.
  • Storage: Store in an airtight container for up to 4 days at room temperature, or freeze for up to a month.
  • Serving: These are incredible when served warm with a scoop of vanilla bean ice cream!
