How to Make Biscoff Brownies
-
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal after baking. This helps ensure a clean release for your delicious Biscoff brownies.
-
Combine 1.5 cups of crushed Biscoff cookie crumbs with 1/4 cup of melted butter in a bowl. Press the mixture firmly into the bottom of the prepared pan evenly, creating a sturdy cookie crust base.
-
Whip 2 eggs along with 1/2 cup granulated sugar and 1/2 cup light brown sugar on high speed until the mixture is light and creamy, about 1 minute. This step is crucial for a fudgy brownie texture that’s irresistible!
-
Mix in 1/2 cup of cooled melted butter and 2 teaspoons of vanilla extract on medium speed until everything is well combined. This will enhance the flavor profile of your brownies beautifully.
-
Sift together 1/2 cup of all-purpose flour, 1/3 cup of unsweetened cocoa powder, and 1/4 teaspoon of baking powder. Gently fold this dry mix into the egg mixture until just combined, ensuring not to overmix for optimal texture.
-
Pour the brownie batter over the cookie crust, smoothing it evenly with a spatula. The rich, thick brownie layer will encase that delightful crust underneath!
-
Warm 1/3 cup of Biscoff spread in the microwave for 5-10 seconds until it’s swirlable. Drop spoonfuls over the brownie layer and carefully use a knife to create a beautiful swirl through the batter.
-
Bake for 22-25 minutes. Check for doneness by inserting a toothpick—it should come out mostly clean with a few moist crumbs. Allow the brownies to cool completely in the pan before cutting into squares.
Optional: Serve warm with a scoop of vanilla ice cream for an indulgent treat!
