Fudgy Biscoff Cookie Butter Brownies Recipe
Biscoff brownies—also called cookie-butter brownies—are an irresistible upgrade to classic brownies. Rich, fudgy (but not too dense) chocolate batter is dotted with creamy Biscoff spread and topped with crunchy Lotus cookies for the perfect balance of texture and flavor.
If you already love recipes that highlight Biscoff cookie butter—like Biscoff cookies, Biscoff cheesecake, cake, donuts, or ice cream—these brownies are an obvious next addition. They combine deep chocolate notes with the warm caramelized spice of Biscoff for a dessert that disappears fast.


INGREDIENTS
The complete recipe with exact measurements is in the recipe section below. Most ingredients are pantry staples and easy to source.
- Unsweetened chocolate (or dark chocolate 65–72%). Do not use milk chocolate.
- Unsalted butter, softened—this gives flavor and helps keep the brownies tender. Do not reduce the butter or the brownies will become cakey.
- Dutch-processed cocoa powder for a deeper chocolate flavor.
- Light brown sugar for moisture and caramel notes.
- Granulated sugar to balance texture.
- Large eggs at room temperature; if you need an alternative, use an appropriate egg substitute.
- Cake flour (or all-purpose flour). Cake flour combined with Dutch cocoa helps create that ideal texture—neither too fudgy nor too cakey.
- Salt to enhance flavor.
- Biscoff cookie butter (cookie butter) for the swirls.
- Lotus Biscoff cookies to top the brownies and add crunch.

HOW TO MAKE BISCOFF BROWNIES
Below are step-by-step instructions; the full recipe card with measurements is included further down.
Before you begin, preheat the oven to 325°F (160°C) and line an 8×8-inch square pan with parchment paper.
- Chop the chocolate and add it to a large microwave-safe bowl with the butter. Melt in 30-second intervals, stirring between bursts, until smooth. Stir in the cocoa powder.
- Add both sugars and mix to combine, then add the eggs.
- Use a whisk to vigorously whisk the eggs into the chocolate mixture until it becomes smooth and glossy. This step helps bind the batter and adds a little air for a better texture.
- Whisk together the flour and salt, then fold the dry mixture into the chocolate until just combined. Avoid overmixing.
- Pour the batter into the prepared pan. Use a small cookie scoop or teaspoon to drop dollops of Biscoff cookie butter on top. Swirl lightly if desired, then arrange Lotus cookies on top.
- Bake for about 20–22 minutes, or until a toothpick inserted in the center comes out with moist crumbs (the center may look slightly underbaked—that’s okay; it will set as it cools).
- Remove from the oven and allow the brownies to cool in the pan before using the parchment overhang to lift them out and slice.


EXPERT TIPS AND FAQ
A few practical tips will help you bake consistently great brownies:
- Create a Biscoff swirl: Microwave the cookie butter for about 15 seconds so it becomes pourable, drop it over the batter, then swirl gently with a knife.
- Room temperature ingredients: Make sure the eggs and butter are at room temperature to ensure even mixing and proper texture.
- Avoid overbaking: The brownies should be slightly underdone in the center when you take them out. They will finish setting as they cool.
- Toothpick test: Check both the center and the edges. The toothpick should come out with a few moist crumbs in the center and slightly drier crumbs at the edges. If it comes out completely dry, the brownies are overbaked.
- Parchment overhang: Leave enough paper on the sides so you can lift the cooled brownies from the pan easily for slicing.
- Slicing tip: Let the brownies cool for 1–2 hours before slicing. For cleaner slices, chill 20 minutes in the fridge, slice, then bring pieces back to room temperature before serving.
YIELDS
This recipe yields one 8×8-inch pan, about 12–16 pieces depending on how large you cut them. To make a 9×13-inch pan, double the recipe and increase baking time while monitoring doneness.
STORING
Store cooled brownies at room temperature in an airtight container for up to 2–3 days.
To freeze, wrap brownies in groups (for convenience) in plastic wrap and place them in a freezer-safe bag for up to 4 weeks. Thaw at room temperature before serving.
