How to Make Biscoff Brownies
-
Melt chocolate – Begin by melting the unsalted butter and chopped chocolate together. Use a double boiler or microwave, heating until smooth. Let the mixture cool slightly to ensure it doesn’t cook the eggs later.
-
Whisk eggs – In a large mixing bowl, whisk together the room temperature eggs, granulated sugar, and vanilla extract until the mixture turns pale and fluffy. This should take about 2-3 minutes, adding air for a light texture.
-
Combine chocolate – Gently fold the cooled chocolate mixture into the egg mixture. Mix until fully incorporated, taking care not to deflate the eggs too much.
-
Add dry ingredients – Sift in the flour, cocoa powder, and salt, and fold everything together with a spatula until just combined. Be cautious not to overmix, as you want your brownies to be fudgy.
-
Incorporate cookies – Stir in the crushed Biscoff cookies until evenly distributed throughout the batter, adding that delightful crunch.
-
Preheat the oven – Set your oven to 350°F (180°C). Prepare an 8-inch square baking pan by lining it with parchment paper for easy removal.
-
Pour batter – Carefully pour the brownie batter into the lined pan and smooth the top with a spatula. Dollop spoonfuls of cookie butter on top and gently swirl it into the batter to create a marbled effect.
-
Bake – Place the pan in the preheated oven and bake for 30-35 minutes. The top should look set while the center remains soft. Use a toothpick to check; it should come out with moist crumbs.
-
Cool completely – After baking, allow the brownies to cool completely in the pan. For cleaner slices, refrigerate for 1 hour before cutting into squares.
Optional: Serve warm with a scoop of vanilla ice cream for an extra indulgent treat.

Tips for the Best Biscoff Brownies
-
Use Quality Ingredients: Choose high-quality chocolate and cookie butter to ensure your Biscoff brownies are rich and flavorful.
-
Room Temperature Eggs: Let your eggs come to room temperature before use; this helps in achieving a better, fudgier texture when mixed.
-
Don’t Overmix: Mix the batter just until combined to maintain that dreamy, gooey center in your brownies—overmixing can lead to cake-like texture.
-
Proper Cooling: Allow the brownies to cool completely in the pan for clean, perfect slices. Chilling them in the fridge for an hour makes cutting easier.
-
Check the Bake Time: It’s better to slightly underbake your brownies. They should be set on top but still soft in the middle for that gooey finish.
How to Store and Freeze Biscoff Brownies
- Room Temperature: Store in an airtight container for up to 3-4 days. Enjoy them fresh for the best gooey texture!
- Refrigerator: Keep covered in the fridge for up to 1 week; this helps enhance the flavors while keeping them moist.
- Freezer: Freeze individual slices wrapped tightly in plastic wrap or foil for up to 3 months. Thaw overnight in the fridge or at room temperature for 30-40 minutes before indulging.
- Reheating: For a warm, melty treat, briefly microwave on low power for about 10-15 seconds—just enough to revive that fudgy goodness.

Biscoff Brownies Recipe FAQs
What kind of chocolate should I use for Biscoff brownies?
Absolutely, I recommend using high-quality baking chocolate or semi-sweet chocolate chips. This will enhance the richness of your brownies and bring out the best chocolate flavor. If you prefer a deeper tone, opt for dark chocolate, but remember that milk chocolate will yield a sweeter result.
How do I know if my Biscoff brownies are done baking?
The key to perfectly gooey Biscoff brownies is to check for doneness carefully. You want the top to be set but the center should still be soft. Around the 30-35 minute mark, use a toothpick to test: it should come out with moist crumbs but not wet batter. If it comes out clean, you’ve likely overbaked them, and they may not have that desired fudgy consistency.
How should I store my Biscoff brownies for freshness?
I often store mine in an airtight container at room temperature for about 3-4 days. To keep them extra moist, you can also refrigerate them, where they will last up to a week. Just remember to cover them well to prevent them from drying out!

Can I freeze Biscoff brownies, and if so, how?
Yes, you can absolutely freeze your Biscoff brownies! First, cool them completely and cut them into individual squares. Wrap each slice tightly in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. To enjoy them later, simply thaw overnight in the fridge or at room temperature for about 30-40 minutes.
Are there any dietary considerations I should keep in mind when making Biscoff brownies?
Very good question! If you’re catering to dietary restrictions, you can use gluten-free flour for a gluten-free version. Keep in mind, though, that traditional cookie butter may contain allergens like wheat and nuts, so be sure to check labels to avoid any issues for those with allergies. Additionally, if you want to keep them vegan, consider using plant-based butter and a substitute for eggs, like flax eggs—just mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water, let it sit for a few minutes until it thickens, and use it instead of one egg.
Can I make Biscoff brownies without a mixer?
Absolutely! One of the best things about this recipe is that it’s a one-bowl wonder, requiring no mixer at all. You can simply melt the butter and chocolate together, then whisk in the eggs and sugar by hand, followed by folding in the dry ingredients. It’s super easy and saves on cleanup time!
