Fudgy Biscoff Brownies Recipe
Introduction
These Fudgy Biscoff Brownies combine rich chocolate with the irresistible caramel flavor of Biscoff spread. Wrapped in a gooey texture and topped with crunchy cookies, they make a perfect treat for any chocolate and cookie butter lover.

Ingredients
- 1 cup Lotus Biscoff Spread (+ 2 tbsp for swirling; you can use other Speculoos cookie butter spread brands)
- ¾ cup butter (regular or vegan, melted)
- 2 eggs
- ¾ cup light brown sugar
- ½ cup granulated sugar
- 2 teaspoons vanilla extract
- ¾ teaspoon salt
- ¾ cup all-purpose flour
- ¾ cup cocoa powder + 2 tbsp
- 8-12 Biscoff cookies or Speculoos cookies (optional)
Instructions
- Step 1: Prepare an 8×8 inch square baking pan by lining it with parchment paper, leaving some paper hanging over the edges for easy removal. Fold the overhanging parchment to create creases along the edges of the pan.
- Step 2: Place the parchment with creases on a flat surface like a cookie sheet or cutting board. Spread 1 cup of cookie butter onto the parchment in a shape that fits the pan. Freeze this while you prepare the brownies.
- Step 3: Preheat your oven to 350°F (175°C) and line the same 8×8 pan again with fresh parchment paper, ensuring overhang for easy removal.
- Step 4: In a bowl, combine cocoa powder, salt, and flour. Set aside.
- Step 5: Melt the butter and transfer it to a medium bowl.
- Step 6: Add both sugars to the melted butter and whisk until the mixture resembles a paste and pulls away from the bowl’s sides.
- Step 7: Mix in the eggs and vanilla extract until smooth.
- Step 8: Gently combine the dry ingredients with the wet ones using a whisk, being careful not to over-mix.
- Step 9: Pour half the batter into the prepared pan. Remove the frozen cookie butter slab from the parchment and place it evenly over the batter.
- Step 10: Pour the remaining batter on top of the cookie butter and smooth the surface.
- Step 11: Arrange Biscoff cookies over the brownie batter, gently pressing them in.
- Step 12: Bake for 30-35 minutes. Check at 30 minutes by inserting a toothpick—it should come out with moist crumbs but no wet batter.
- Step 13: Allow the brownies to cool completely in the pan before using the parchment overhang to lift them out and slice.
Tips & Variations
- For a vegan version, use vegan butter and substitute eggs with flax eggs or a commercial egg replacer.
- If you prefer a swirl effect, warm the extra 2 tablespoons of Biscoff spread and swirl it gently into the brownie batter before baking.
- You can add chopped nuts like walnuts or pecans for extra crunch.
- Replace Biscoff cookies topping with chocolate chips or chunks for a different texture.
Storage
Store the cooled brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate and consume within a week. Reheat briefly in the microwave to regain softness, or enjoy chilled for a fudgier texture.

FAQs
Can I use a different size pan?
Yes, but the baking time may vary. A smaller pan will produce thicker brownies and require more baking time, while a larger pan will make thinner brownies and need less time.
What if I don’t have Biscoff spread?
You can substitute with any Speculoos cookie butter spread or another caramel-like nut butter. While the flavor will change, it will still add a lovely richness.

- 1 cup Lotus Biscoff Spread (plus 2 tbsp for swirling, optional: other Speculoos cookie butter brands)
- ¾ cup butter (regular or vegan, melted)
- 2 eggs
- ¾ cup light brown sugar
- ½ cup granulated sugar
- 2 teaspoons vanilla extract
- ¾ teaspoon salt
- ¾ cup all-purpose flour
- ¾ cup cocoa powder + 2 tbsp (for batter and swirling)
Topping
- 8–12 Biscoff cookies or Speculoos cookies (optional)
Instructions
- Prepare the pan and cookie butter layer: Line an 8×8-inch square baking pan with parchment paper, leaving some paper overhanging the edges for easy removal. Fold the overhanging parchment edges to create a crease along the pan’s edges. Spread the cookie butter in a square shape fitting the pan onto the parchment paper and freeze it while you prepare the batter.
- Preheat oven and prepare baking pan: Preheat your oven to 350°F (175°C). Line the same 8×8-inch pan again with fresh parchment paper, ensuring an overhang for easy brownie removal after baking.
- Mix dry ingredients: In a bowl, combine ¾ cup cocoa powder, ¾ teaspoon salt, and ¾ cup all-purpose flour. Set aside.
- Melt butter and cream with sugars: Melt the ¾ cup butter and transfer to a medium bowl. Add ¾ cup light brown sugar and ½ cup granulated sugar. Whisk together until the mixture thickens into a paste that pulls away from the sides of the bowl.
- Add eggs and vanilla: Whisk in 2 eggs and 2 teaspoons vanilla extract until smooth and combined.
- Combine wet and dry mixtures: Gently fold the dry ingredients into the wet mixture using a whisk or spatula, taking care to avoid overmixing to keep the brownies tender.
- Assemble brownie layers: Pour half of the brownie batter into the prepared pan and spread evenly. Remove the frozen cookie butter square from the parchment and place it gently over the batter.
- Add remaining batter and cookies: Pour the remaining batter over the cookie butter layer, leveling the surface. Arrange 8-12 Biscoff cookies on top, gently pressing them into the batter for added texture.
- Bake the brownies: Bake in the preheated oven for 30-35 minutes. Check at 30 minutes by inserting a toothpick—the brownies should have moist crumbs but no wet batter.
- Cool and serve: Allow the brownies to cool completely in the pan before using the parchment paper overhang to lift them out and slice.
