• 3½ cups powdered sugar – Sweetens and thickens the buttercream.
• 1 cup smooth Biscoff cookie butter – Provides the frosting’s rich cookie butter flavor.

Step-by-Step Instructions

Step 1: Prepare the Cake Pans

Preheat the oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, or line them with parchment paper and lightly coat with non-stick spray.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, granulated sugar, baking powder, and ¼ teaspoon of the salt until evenly combined.

Step 3: Cream the Butter

In a large mixing bowl, beat the softened butter with an electric mixer for about 2 minutes until light and fluffy. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract and Biscoff cookie butter until smooth.

Step 4: Prepare the Batter

Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the flour mixture. Mix only until everything is incorporated to keep the cake tender.

Step 5: Bake the Cake Layers

Divide the batter evenly between the prepared cake pans. Bake for 25–28 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 6: Make the Biscoff Buttercream

Beat the softened butter for 3–4 minutes until light and fluffy. Gradually add the powdered sugar, mixing on low speed before increasing to medium. Add the Biscoff cookie butter, remaining vanilla extract, remaining salt, and enough heavy cream to achieve a smooth, spreadable consistency.

Step 7: Assemble the Cake

If necessary, level the tops of the cooled cake layers with a serrated knife. Place one cake layer on a serving plate and spread about ¾ cup of buttercream over the top. Add the second cake layer and frost the top and sides evenly with the remaining buttercream.

Step 8: Decorate and Serve

Press the crushed Biscoff cookies around the base and sprinkle additional crumbs over the top of the cake. Slice and serve at room temperature for the best flavor and texture.

Recipe Notes & Tips

• Use Room Temperature Ingredients – Butter, eggs, and milk combine more smoothly for a lighter cake.
• Don’t Overmix the Batter – Mix only until the flour disappears to keep the cake soft and fluffy.
• Warm the Cookie Butter if Needed – Microwave it for 15–20 seconds if it’s too firm to mix easily.
• Brush with Simple Syrup – Lightly brushing the cooled cake layers with simple syrup creates an even moister cake.
• Cool Completely Before Frosting – Warm cake layers can cause the buttercream to melt and slide.
• Measure Flour Correctly – Spoon the flour into the measuring cup and level it off to avoid a dense cake.

Why This Recipe Works

This Biscoff Cake combines classic cake-making techniques with the rich caramelized flavor of cookie butter to create an exceptionally moist and flavorful dessert. Creaming the butter and sugar incorporates air into the batter, producing a light crumb, while whole milk and Biscoff spread add moisture and richness. Alternating the dry ingredients with the milk prevents overmixing, helping maintain a tender texture. The buttercream blends butter, powdered sugar, and cookie butter into a silky frosting that’s both stable and incredibly flavorful. Crushed Biscoff cookies provide a crunchy contrast that complements the smooth frosting and soft cake layers. At approximately 620 calories per slice, this dessert is a decadent treat that’s perfect for celebrations and special occasions.

It’s surprisingly simple to make yet impressive enough to serve at birthdays, holidays, and family gatherings. Whether you’re baking for a celebration or simply treating yourself, this cake delivers rich caramelized flavor and beautiful presentation every time. If you’d like a slightly lighter version, you can reduce the frosting between the layers, use light cream cheese frosting instead of buttercream, or serve smaller slices alongside fresh berries for a balanced dessert experience.
