If you’re a fan of cookie butter, this Biscoff Cake (Cookie Butter Layer Cake) is the ultimate indulgence. Moist layers of sponge cake are sandwiched with creamy Biscoff buttercream and finished with crunchy cookie crumbles, creating a dessert that is as visually stunning as it is delicious. Perfect for birthdays, holidays, or weekend baking projects, this cake elevates the humble cookie butter into a show-stopping centerpiece.

Why This Biscoff Cake Stands Out

Unlike simple cakes, this layered Biscoff Cake is all about flavor balance. The soft, tender sponge pairs perfectly with the rich, caramelized flavor of Biscoff buttercream. Crushed Biscoff cookies add texture, creating a contrast to the smooth frosting. Every bite is a mix of melt-in-your-mouth cake, creamy sweetness, and subtle spice notes from the cookies themselves.

Ingredients

Cake Layers:

2 ½ cups all-purpose flour
2 ½ tsp baking powder
½ tsp salt
½ cup unsalted butter, softened
1 cup granulated sugar
4 large eggs
1 tsp vanilla extract
1 cup milk

Biscoff Buttercream:

1 cup unsalted butter, softened
1 ½ cups powdered sugar
1 cup Biscoff spread
2–3 tbsp heavy cream
1 tsp vanilla extract

Decoration:

Crushed Biscoff cookies for garnish

Instructions

Preheat oven and prepare pans: Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
Mix dry ingredients: In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
Cream butter and sugar: In a large bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
Combine wet and dry ingredients: Alternately add flour mixture and milk to the creamed butter mixture, starting and ending with flour, mixing until just combined.
Bake layers: Divide batter evenly among prepared pans. Bake 25–30 minutes or until a toothpick inserted in the center comes out clean. Cool completely on wire racks.
Make buttercream: Beat butter until smooth. Add powdered sugar gradually, then mix in Biscoff spread, heavy cream, and vanilla extract until fluffy and spreadable.
Assemble the cake: Place one cake layer on a serving plate. Spread a layer of buttercream evenly. Repeat with second layer. Top with the final layer and frost the top and sides with remaining buttercream.
Decorate: Sprinkle crushed Biscoff cookies on top for garnish. Chill the cake for at least 30 minutes before serving for easier slicing.

Tips for the Perfect Biscoff Cake

Room temperature ingredients: Ensure eggs, milk, and butter are at room temperature for smooth batter and even baking.
Level your layers: Use a serrated knife or cake leveler to ensure even layers before assembling.
Chill for clean slicing: Refrigerating the cake for 30 minutes makes slicing cleaner and prevents smearing of buttercream.
Storage: Store covered in the fridge for up to 4–5 days. Bring to room temperature before serving for optimal flavor.

Variations to Try

Chocolate Biscoff Cake: Add ¼ cup cocoa powder to the flour mixture for a chocolate twist.
Vegan option: Use plant-based butter and flax eggs; coconut cream can replace heavy cream.
Mini cakes or cupcakes: Use the same batter to make cupcakes and top with Biscoff buttercream.
Layer flavor additions: Add thin layers of caramel or sliced bananas between cake layers for added richness.

Serving Suggestions

Celebration dessert: Perfect centerpiece for birthdays, anniversaries, or holiday gatherings.
Coffee pairing: Pairs beautifully with a cup of coffee or chai tea.
Party-friendly: Slice into mini squares for serving at parties or potlucks.
Gift-worthy: Wrap in a cake box and give as a homemade gift for special occasions.
