- Wire rack
Ingredients
- 3/4 cup Biscoff cookie butter (smooth, adds warmth and sweetness)
- 1/2 cup light or dark brown sugar, packed (moisture and depth of flavor)
- 1/2 cup granulated sugar (sweetness and structure)
- 2 large eggs (binding agent, adds moisture)
- 1 large egg yolk (richness)
- 1 tablespoon vanilla extract (aroma and flavor)
- 10 tablespoons unsalted butter (fat content for creaminess)
- 2/3 cup + 1/4 cup semi-sweet chocolate chips (melts for richness)
- 1/4 cup unsweetened Dutch cocoa powder (chocolate flavor and color)
- 2/3 cup + 1 tablespoon all-purpose flour (structure)

How to Make Biscoff Cookie Butter Brownies
Step 1. Begin by pressing a large piece of parchment paper into an 8×8 metal baking pan. Make sure the edges are fitting snugly against the sides and bottom. Chilling the pan for a few minutes will help the parchment hold its shape, making it easier to lift out the brownies later.
Step 2. Preheat your oven to 350°F. This is an essential step to ensure that the brownies bake evenly and rise properly once the batter is ready to go in.
Step 3. In a mixing bowl, whisk together the packed light or dark brown sugar, granulated sugar, large eggs, large egg yolk, and vanilla extract. Mix until everything is well-combined and slightly frothy, which indicates that you have incorporated some air into the mixture for a lighter texture.
Step 4. Next, melt the unsalted butter and semi-sweet chocolate chips together until smooth, which can be done in a microwave or on the stovetop. Once melted, whisk in the cocoa powder along with the previously mixed egg mixture until everything is well integrated.
Step 5. Carefully fold in the all-purpose flour, espresso powder, and fine sea salt with a spatula. Mix until just combined to prevent overworking the batter, which would result in a denser brownie instead of a fudgy texture.
Step 6. Pour half of the brownie batter into the prepared baking pan. Allow it to spread evenly across the bottom. Next, place a square of frozen Biscoff cookie butter on top of this layer, and then gently pour the remaining batter over it, ensuring that the cookie butter is covered and well-embedded.
Step 7. Break the 4-5 Biscoff cookies into pieces and sprinkle them over the top of the batter. Drizzle warmed cookie butter over the cookie pieces. This creates an extra layer of flavor and visual appeal, which will caramelize as it bakes.
Step 8. Place the pan in the preheated oven and bake for 30-40 minutes. Keep an eye on them towards the end; they are done when a toothpick inserted in the center comes out with a few moist crumbs, indicating a fudgy texture.
Step 9. Once baked, allow the brownies to cool in the pan on a wire rack. This step is crucial for setting their structure before removing them. If desired, you can drizzle more cookie butter on top after they cool before serving to add an extra touch of indulgence.

Serving Suggestions
These brownies are versatile enough to enjoy at any time of day. Serve them warm for breakfast alongside your morning coffee or as an afternoon treat with tea. They make a delightful dessert for family meals, and they’re also great for potlucks or gatherings where you’ll want to impress guests. If you have leftovers, they will satisfy your sweet cravings for days, and they hold up well when wrapped and stored.
Pro Tips for Best Results
- Ensure your eggs are at room temperature for better incorporation into the batter.
- Don’t skip the espresso powder; it enhances the chocolate flavor, offering a richer final product.
- For a fudgier brownie, avoid over-baking. Check for doneness with a toothpick in the center.
- Let the brownies cool completely before cutting to achieve cleaner edges.
- Try drizzling the extra cookie butter just before serving for a fresh touch.
Common Mistakes to Avoid
- Over-mixing the batter: This can lead to tough brownies rather than fudgy ones. Mix until just combined.
- Not lining the pan properly: Failing to line the pan with parchment may result in sticking. Make sure to press it tightly into the corners.
- Skipping the chilling step: Not chilling the parchment may make it harder to lift out the brownies. A brief chill can help.
- Using cold butter or chocolate: If the mixture cools too much before combining ingredients, it may create lumps. Melt them until smooth and mix while the mixture is still warm.
- Ignoring texture cues for doneness: Baking times may vary; always rely on visual cues and toothpick tests rather than solely following a time.
- Cutting brownies before they cool: This will result in messy, uneven pieces. Patience is key for clean cuts.
Variations & Substitutions
- You can use a combination of different chocolate chips, like milk chocolate or dark chocolate, if desired.
- For a nutty flavor, consider adding chopped walnuts or pecans to the batter if you like.
- If you want a more distinct spice profile, a pinch of cinnamon can add warmth that complements the cookie butter nicely.
Storage & Reheating
Store the brownies at room temperature in an airtight container for up to three days. If you’d like to keep them longer, refrigerate them for up to a week, wrapped tightly to prevent drying out. These brownies can also be frozen for about three months. For the best texture, thaw them in the refrigerator overnight and enjoy them at room temperature or warmed slightly in the microwave for a few seconds.
