Ingredients
Biscoff Cookie Crust

- ¼ cup salted butter, melted and cooled (56g)
Biscoff Brownies
- 2 large eggs, room temperature (112g)
- ½ cup granulated sugar (100g)
- ½ cup packed light brown sugar (100g)
- ½ cup salted butter, melted and cooled (113g)
- 2 tsp vanilla extract or vanilla bean paste (8g)
- ½ cup all-purpose flour (65g)
- ⅓ cup unsweetened baking cocoa (33g)
- ¼ tsp baking powder (>1g)
- ⅓ cup smooth Biscoff cookie butter (80g)
Instructions for Ultimate Biscoff Brownies
- Preheat the oven to 350°F (175°C) and line an 8-inch square baking pan with parchment paper. Set aside.
- Combine crushed Biscoff cookies and melted butter for the crust. Press evenly into the prepared pan using the back of a spoon.
- In a large bowl, beat eggs, granulated sugar, and brown sugar on high speed until creamy and light in color (~1 minute).
- Add melted butter and vanilla extract, mixing on medium until fully incorporated.
- Sift together flour, cocoa powder, and baking powder. Gradually fold into the wet mixture with a rubber spatula until smooth.
- Pour brownie batter over the Biscoff crust and spread evenly.
- Heat Biscoff spread for 5-10 seconds in the microwave, then spoon over the brownie batter. Swirl gently with a knife for a marbled effect.
- Bake for 22-25 minutes, or until a toothpick inserted comes out mostly clean. Cool completely before slicing.
