How to Make 6in 2 layer biscoff cake filled with creamy biscoff butter, biscoff cookie pieces, biscoff buttercream

1. Preheat your oven to 350°F and grease two 6-inch round cake pans, then line the bottoms with parchment paper for easy removal.
2. In a medium bowl, whisk together the flour, baking powder, and salt; set aside.
3. In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes. Add eggs one at a time, mixing well after each, then stir in vanilla extract and biscoff spread.
4. Alternately add the dry ingredients and milk to the wet mixture, beginning and ending with the dry ingredients. Mix until just combined, then fold in the chopped biscoff cookie pieces gently.
5. Divide the batter evenly between the prepared pans and smooth the tops. Bake for 28-32 minutes until a toothpick inserted in the center comes out clean. Let cakes cool completely in pans for 10 minutes before transferring to a wire rack.
6. While cakes cool, make the biscoff buttercream by beating the softened butter until creamy, then gradually adding powdered sugar. Mix in biscoff spread and salt, adding heavy cream one tablespoon at a time until the buttercream is smooth and spreadable.
7. Place one cake layer on your serving plate and spread about half the buttercream evenly over the top. Place the second cake layer on top and use the remaining buttercream to frost the top and sides of the cake evenly.
8. For a finishing touch, sprinkle extra chopped biscoff cookie pieces or drizzle a little biscoff spread on top.
9. Chill the cake for 30 minutes before slicing to let the buttercream set and flavors meld.

Tips for the Best Results

• Use room temperature butter and eggs for a smooth batter and even baking.
• Don’t overmix the batter; fold in the cookie pieces gently to maintain texture.
• Make sure cakes are completely cool before frosting to prevent melting the buttercream.
• For extra moisture, brush cake layers with a simple syrup infused with a teaspoon of vanilla before frosting.
• Store leftover cake covered tightly to keep it fresh and prevent drying out.

Storage and Reheating

This biscoff cake keeps best when stored in an airtight container in the refrigerator for up to 4 days. The buttercream filling will stay creamy and fresh, making each slice deliciously moist.

You can also freeze the cake wrapped tightly in plastic wrap and foil for up to 2 months. Thaw it overnight in the refrigerator before serving. Avoid reheating as the buttercream may melt; instead, enjoy it chilled or at room temperature.

Frequently Asked Questions

Can I make this cake bigger or smaller?

Absolutely! You can adjust the ingredient quantities to bake larger or smaller cakes. Just keep the layering consistent and adjust baking time accordingly, checking with a toothpick.

Can I substitute biscoff spread with cookie butter from another brand?

Yes, any smooth cookie butter spread with similar flavors will work well as a substitute for biscoff spread in both the batter and buttercream.

How do I prevent the cookie pieces from sinking in the batter?

Lightly tossing the chopped cookie pieces in a tablespoon of flour before folding them into the batter helps keep them suspended evenly throughout the cake layers.

Is this cake gluten-free?

This recipe uses regular all-purpose flour, so it’s not gluten-free. However, you could try a 1:1 gluten-free flour blend, but results may vary slightly.
