What Kind of Butter Should I Use?
For this Biscoff Brownies recipe, it is best to use unsalted butter, specifically one that is high-quality and freshly purchased. Unsalted butter allows you to control the saltiness of your brownies while enhancing the rich, decadent flavor that complements the Biscoff spread perfectly. The melting process helps create a fudgy texture, which is essential for achieving that indulgent brownie mouthfeel. If you only have salted butter on hand, you can still use it—just reduce the added salt in the recipe to ensure your brownies don’t turn out too salty.
Ingredients for the Biscoff Brownies
Each ingredient in this dish plays an essential role in flavor and texture. Here’s what you’ll need:
- 1 cup unsalted butter (melted): Provides richness and moisture, ensuring a fudgy brownie.
- 1 cup granulated sugar: Sweetens the brownies, contributing to their delightful texture and flavor.
- 2 large eggs: Bind the ingredients together while adding structure and moisture.
- 1 teaspoon vanilla extract: Enhances the overall flavor profile with a warm sweetness.
- 1 cup all-purpose flour: Forms the base of the brownies, giving them structure.
- 1/2 cup cocoa powder (unsweetened): Infuses a deep chocolate flavor, making each bite indulgent.
- 1/2 teaspoon baking powder: Helps the brownies rise slightly, creating a light texture.
- 1/4 teaspoon salt: Balances sweetness and enhances all the flavors in the dish.
- 1/2 cup Biscoff spread (plus extra for drizzling): Adds a unique caramelized flavor and creamy texture that elevates the brownies.
How To Make This Recipe

Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C). While it’s heating, grease an 8×8 inch baking pan with butter or cooking spray and line it with parchment paper, allowing some overhang for easy removal later. This will ensure your brownies come out easily and have a nice, even edge.
Mix Butter and Sugar
In a mixing bowl, whisk together the melted unsalted butter and granulated sugar until the mixture is smooth and well combined. This process should take about 1-2 minutes, and the mixture should be glossy, indicating that the sugar is starting to dissolve into the butter.
Incorporate Eggs and Vanilla
Add the two large eggs and the teaspoon of vanilla extract to your butter-sugar mixture. Mix everything together until fully combined, which should take another minute. The batter should look slightly thicker and more homogenous at this stage.
Sift Dry Ingredients
In another bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt. Sifting helps to aerate the dry ingredients and break up any clumps in the cocoa powder, ensuring a smoother brownie texture.
Combine Wet and Dry Mixtures
Gradually add the dry ingredient mixture into your wet ingredients, stirring gently just until combined. Be careful not to overmix; you want to see a few streaks of flour remaining as this will help keep your brownies tender.
Fold in Biscoff Spread
Now it’s time to fold in the ½ cup of Biscoff spread into your brownie batter. Use a spatula to gently incorporate it until evenly distributed throughout the batter. The Biscoff spread will give a rich flavor that enhances every bite.
Pour Batter into Prepared Pan
Pour your brownie batter into the prepared baking pan, using a spatula to smooth out the top for even baking. Make sure there are no air bubbles trapped beneath by gently tapping the pan on your countertop once before placing it in the oven.
Bake Until Set
Bake in your preheated oven for 25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs attached. You want to avoid overbaking; if it comes out clean, your brownies may be dry instead of fudgy.
Beat Together Frosting Ingredients
In a mixing bowl, beat together ½ cup of softened unsalted butter and ½ cup of Biscoff spread until creamy and well blended. This should take about 2-3 minutes on medium speed; you’re looking for a light texture that’s easy to spread.
Add Powdered Sugar Gradually
Gradually add in 1 cup of powdered sugar while continuing to mix until fully combined. The frosting may be thick at first but will become smoother as you mix; aim for a spreadable consistency without being too runny.
Adjust Consistency with Milk
To achieve your desired frosting consistency, add 1 tablespoon of milk as needed while mixing continuously. If it seems too thick, feel free to add a little more milk—just do so sparingly until it’s perfect for spreading on your brownies.
Frost Cool Brownies
Once your brownies are completely cooled down in the pan, spread an even layer of Biscoff frosting over the top using an offset spatula. Take care not to disturb any edges or corners for a clean finish.
Drizzle Extra Biscoff Spread
For an extra touch of indulgence, drizzle additional Biscoff spread over the frosted brownies before cutting them into squares. This not only enhances presentation but also intensifies that delicious flavor profile with every bite.
Cut and Serve
Finally, lift your brownies out of the pan using the parchment paper overhang and cut them into squares. Serve these decadent treats immediately or store them in an airtight container for later enjoyment!
How to Serve and Store Biscoff Brownies
These Biscoff Brownies yield 4 rich and decadent servings, perfect for sharing with a friend or indulging in a sweet treat. Serve them warm, drizzled with extra Biscoff spread, alongside a scoop of vanilla ice cream for a delightful contrast in temperature and texture. For an elegant touch, plate them with a sprinkle of crushed Biscoff biscuits on top and a dollop of whipped cream to enhance their irresistible appeal.
To store any leftovers, place the brownies in an airtight container in the refrigerator, where they will stay fresh for up to five days. When you’re ready to enjoy them again, gently reheat in the microwave for about 10-15 seconds at low power to maintain their fudgy texture without drying them out. While these brownies can be frozen, be aware that the frosting may lose some of its creamy consistency upon thawing, so it’s best enjoyed fresh.
What to Serve With Biscoff Brownies
Vanilla Ice Cream
The creamy, cool vanilla ice cream enhances the warm, fudgy texture of the Biscoff brownies, creating a delightful contrast.
Roasted Brussels Sprouts
The slight bitterness of roasted Brussels sprouts balances the sweetness of the brownies while adding a satisfying crunch.
Garlic Bread
Savory garlic bread complements the sweet flavors of the Biscoff brownies, providing a deliciously unexpected savory-sweet combination.
Mixed Green Salad
A fresh mixed green salad with a light vinaigrette offers a refreshing palate cleanser that beautifully offsets the richness of the brownies.
Creamy Mashed Potatoes
Rich and buttery mashed potatoes provide a comforting side that contrasts with the brownie’s sweet decadence while enhancing its indulgent nature.
Caramelized Apples
Sweet and slightly tart caramelized apples bring a fruity note that pairs wonderfully with the spiced flavor profile of Biscoff spread.
Can I use margarine instead of unsalted butter? Yes, you can substitute margarine for unsalted butter in the brownie base. However, keep in mind that margarine may slightly alter the flavor and texture, so choose a high-quality brand for the best results.
Are these brownies gluten-free? Unfortunately, this recipe is not naturally gluten-free due to the all-purpose flour. To make gluten-free Biscoff brownies, simply substitute the all-purpose flour with a gluten-free flour blend that can be used as a 1: 1 replacement.
Can I make these brownies ahead of time and freeze them? Absolutely! You can bake the brownies, allow them to cool completely, and then wrap them tightly in plastic wrap before freezing. They can be stored in the freezer for up to three months; just thaw and frost when you’re ready to serve.
How do I know when the brownies are done baking? The brownies are done when a toothpick inserted into the center comes out with a few moist crumbs attached. If it comes out clean, they may be overbaked, so check around the 25-minute mark.
Can I add nuts or other mix-ins to the brownie batter? Yes, you can definitely add nuts like walnuts or pecans to enhance texture and flavor. Just fold in about half a cup of your preferred mix-ins after adding the Biscoff spread for a delicious twist!
