Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Unsalted butter provides richness and moisture.

Granulated sugar sweetens and contributes to a crackly top.

Brown sugar adds depth and subtle caramel notes.

Eggs create structure and help achieve a fudgy texture.

Vanilla extract enhances warmth and flavor.

All-purpose flour forms the base structure.

Unsweetened cocoa powder delivers intense chocolate flavor.

Salt balances sweetness.

Biscoff spread adds creamy, spiced caramel flavor.

Chocolate chips provide extra pockets of melted chocolate.

Crushed Biscoff cookies can be folded in for added texture.

Directions

Preheat the oven and line a baking pan with parchment paper. Melt butter and allow it to cool slightly.

In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs one at a time, mixing thoroughly after each addition. Stir in vanilla extract.

Fold in flour, cocoa powder, and salt until just combined. Avoid overmixing to maintain a fudgy texture.

Pour the batter into the prepared pan and smooth the surface. Warm the Biscoff spread slightly to loosen it, then spoon dollops over the batter. Use a knife to gently swirl it into the top layer.

Sprinkle chocolate chips or crushed cookies over the top if desired. Bake until the edges are set and the center remains slightly soft. Allow to cool completely before slicing.

Variations and Customizations

Biscoff Brownies are highly adaptable. I tested this recipe with a thin layer of Biscoff spread sandwiched in the center, which created an even more indulgent result.

For extra crunch, mix chopped walnuts into the batter. You can also top the brownies with a drizzle of melted chocolate for a more decorative finish.

If you prefer a stronger Biscoff presence, increase the amount slightly while keeping the batter balanced. These variations allow flexibility while preserving the rich, fudgy base.
