For the Brownie Batter
- 250 g (8.8 oz or 1 1/2 cups) Baking Chocolate – or semi-sweet chocolate chips
- 115 g (1 stick) Butter – unsalted
- 4 Eggs – at room temperature
- 200 g (1 cup) Sugar – granulated
- 1 1/2 tsp Vanilla extract
- 90 g (3/4 cup) Flour – Cake flour or all-purpose

How to Make Fudgy Biscoff Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F / 180°C. Line your square baking pan with baking paper to prevent sticking.
Step 2: Melt the Chocolate and Butter
In a heatproof bowl, combine the butter and chocolate pieces. Melt them together using a double boiler or microwave until completely smooth.
Step 3: Beat Eggs and Sugar
In a large mixing bowl, whisk together the room-temperature eggs, granulated sugar, and vanilla extract using an electric whisk for about 2 minutes until fluffy.
Step 4: Combine Wet Ingredients
Add the melted chocolate mixture into the egg mixture. Whisk again until well incorporated.
Step 5: Mix Dry Ingredients
Sift in the flour, cocoa powder, and salt. Use a flexible spatula to gently fold the dry ingredients into the wet mixture.
Step 6: Add Cookie Chunks
Fold in the crushed Lotus Biscoff cookies until evenly distributed throughout the batter.
Step 7: Transfer to Pan
Pour the brownie batter into your prepared pan. Smooth out the top using an angled spatula for an even surface.
Step 8: Swirl in Biscoff Spread
Dollop teaspoons of Lotus Biscoff spread on top of the batter. Use a knife blade to swirl it into the mixture for added flavor.
Step 9: Bake
Bake in your preheated oven for about 30-35 minutes. Check doneness by inserting a toothpick; it should come out with crumbs but not wet batter.
Step 10: Cool and Chill
Once baked, remove from oven and let cool completely at room temperature. Then cover with plastic wrap and chill in the fridge for an hour before cutting.
Step 11: Serve
Cut into equal pieces—16 slices—and enjoy your Fudgy Biscoff Brownies on their own or plated with vanilla ice cream!

Common Mistakes to Avoid

- Skipping the chilling step – Cutting brownies before they cool completely may result in messy pieces. Allow them to cool and chill for cleaner cuts.
