Instructions
Preparing the Cookie Layer
- Preheat the Oven: Set the oven to 160°C (320°F) for fan-forced or 170°C (340°F) for a conventional oven. Spray a 9-inch square baking tin with oil and line it with baking paper, ensuring there’s overhang for easy removal.
- Mix the Dry Ingredients: In a small bowl, whisk the flour and baking powder until combined. Set aside.
- Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, brown sugar, caster sugar, salt, and vanilla extract with an electric mixer until light and fluffy—about 3 minutes.
- Incorporate the Egg: Add the egg and beat until well combined.
- Form the Dough: Gradually fold in the dry ingredients and chocolate chips with a spatula until a soft dough forms.
- Assemble the Base: Press the dough evenly into the prepared tin using your hands or a spatula. Refrigerate the base while preparing the brownie layer.
Creating the Brownie Layer
- Melt the Chocolate: Combine the butter and dark chocolate in a heatproof bowl. Microwave in 30-second increments, stirring each time, until smooth. Alternatively, use a double boiler. Set aside to cool slightly.
- Combine Dry Ingredients: Whisk together the flour, cocoa powder, and salt in the same bowl used for the cookie layer’s dry ingredients.
- Whip Eggs and Sugars: In a large mixing bowl, beat the eggs, caster sugar, brown sugar, and vanilla extract with an electric mixer on high speed until pale, fluffy, and doubled in volume—2 to 3 minutes.
- Add Coffee and Chocolate: Stir in the coffee shot, then gently fold in the melted chocolate mixture until fully incorporated.
- Incorporate Dry Ingredients: Gradually fold in the dry ingredients with a spatula, mixing until no streaks of flour remain.
Assembling and Baking
- Layer the Oreos: Arrange the double-stuffed Oreos in a single layer over the cookie dough base.
- Pour the Brownie Batter: Spread the brownie mixture evenly over the Oreos, ensuring every corner is covered.
- Bake: Place the tin in the oven and bake for 22-25 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Avoid overbaking for maximum fudginess.
- Cool and Slice: Allow the bars to cool completely at room temperature. For cleaner slices, refrigerate for 2 hours before cutting. Use a hot, dry knife for precise cuts.
Notes
- Measure by Weight: For best results, use kitchen scales to measure ingredients. Cup measurements can vary, impacting the texture and consistency.
- Use High-Quality Chocolate: Opt for dark cooking chocolate for a richer, smoother finish in the brownie layer.
- Refrigeration is Key: Cooling the bars in the fridge ensures clean, sharp slices and enhances the flavors.
- Customize the Layers: Swap double-stuffed Oreos for flavored varieties like peanut butter or mint for a unique twist.
- Prep Time: 15 minutes
- Cook Time: 40 minutes
