The Full Cookie Butter Brownies Recipe
Ingredients
- **For Biscoff Crust:**
- 16 oz (2 sleeves) Biscoff cookies, divided
- 1/2 cup (115g) butter, melted
- 2 tbsp (25g) granulated sugar
- **For Biscoff Brownies:**
- 1 cup (225g) butter, melted
- 2 cups (400g) granulated sugar
- 2 tsp vanilla extract
- 4 large eggs, at room temperature
- 1 1/4 cups (125g) cocoa powder
- 1/2 cup (65g) all-purpose flour
- 1/4 tsp salt
- 1/2 cup cookie butter
- **For Cookie Butter Frosting:**
- 1/2 cup (115g) butter, softened
- 3/4 cup cookie butter
- 2-3 cups (240-360g) powdered sugar
- 1 tsp vanilla extract
- 3-4 tbsp heavy whipping cream
Instructions
- Prepare the Crust: Line a 9-inch square pan with foil, allowing the edges to hang over. Lightly coat with nonstick spray. This will help remove the brownies easily after baking.
- Crush the Biscoff cookies into fine crumbs using a food processor or by placing them in a gallon-sized Ziploc bag and smashing with a rolling pin. Set aside 1/4 cup of crumbs for garnish.
- In a medium bowl, mix the remaining cookie crumbs with melted butter and sugar. Press this mixture firmly into the bottom of the prepared pan. Make sure to pack it tightly to form a solid crust.
- Make the Brownies: In a large bowl, whisk together the melted butter, granulated sugar, and vanilla extract until well combined. This step helps create a smooth batter.
- Add the eggs one at a time, whisking well after each addition. This ensures the mixture emulsifies properly.
- Stir in the cocoa powder, flour, and salt until just blended. Be careful not to overmix to keep the brownies fudgy.
- Spread the brownie batter evenly over the crust. Use a spatula for an even layer.
- In a small heatproof bowl, melt the cookie butter in the microwave for 20-30 seconds, stirring until smooth. Drizzle the melted cookie butter over the brownie batter and lightly swirl it with a knife for a marbled effect.
- Bake in a preheated oven at 350°F (175°C) for 40-45 minutes, or until the edges and center are set. A toothpick inserted near the center should come out mostly clean with a few moist crumbs. Keep an eye on it, as ovens can vary.
- Allow the brownies to cool in the pan on a wire rack. Once completely cool, run a knife around the edges and lift the brownies out using the foil overhang. Transfer to a plate or serving platter.
- Prepare the Frosting: In a large mixing bowl, beat the softened butter and cookie butter together until smooth. This creates a creamy base for the frosting.
- Gradually add the powdered sugar, mixing until smooth. Adjust the sweetness to your preference.
- Beat in the vanilla extract. This adds a lovely aroma and flavor to the frosting.
- Add heavy cream, one tablespoon at a time, until the frosting is light, fluffy, and spreadable. This will help achieve the perfect texture.
Serving Suggestions and Variations for Cookie Butter Brownies
These Cookie Butter Brownies are delightful on their own, but you can elevate them even further! Consider serving them warm with a scoop of vanilla ice cream for a decadent dessert. For a festive touch, sprinkle the reserved Biscoff crumbs on top of the frosting or add chopped nuts or chocolate chips to the brownie batter for added texture. If you want to make them a bit healthier, try substituting half of the butter with applesauce for a lighter version.
