Ingredients

All-purpose flour
Baking powder
Salt
Unsalted butter (room temperature)
Granulated sugar
Eggs
Vanilla extract
Whole milk
Biscoff cookie butter spread
Biscoff cookies (crushed, for garnish)
Powdered sugar (for the frosting)
Heavy cream (optional, for smoother buttercream)

Directions

Preheat the oven to 350°F (175°C). Grease and line three 8-inch cake pans.
Make the cake batter: In a medium bowl, whisk together flour, baking powder, and salt. In a large bowl, beat butter and sugar until light and fluffy. Add eggs one at a time, then stir in vanilla and Biscoff spread until well combined.
Combine dry and wet ingredients: Alternate adding the flour mixture and milk to the wet mixture, beginning and ending with the flour. Mix until just combined.
Bake for 25–30 minutes or until a toothpick inserted into the center comes out clean. Cool the cakes in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Prepare the frosting: Beat butter until smooth, then add Biscoff spread and powdered sugar. Add cream a tablespoon at a time to reach desired consistency.
Assemble the cake: Place the first cake layer on a stand, spread a layer of frosting, and repeat with the remaining layers. Frost the top and sides.
Decorate with crushed Biscoff cookies and additional swirls of frosting or drizzle of melted cookie butter if desired.
Chill or serve immediately, depending on your preference.

FAQs

What is Biscoff?

Biscoff is a brand of speculoos cookies with a distinct caramelized flavor, often enjoyed with coffee. The spreadable version, known as cookie butter, is made from these cookies and used in both baking and desserts.

Can I make this cake ahead of time?

Yes, you can bake the cake layers a day or two in advance. Wrap them well and store them at room temperature or freeze them for longer storage. Assemble and frost the cake on the day of serving for best results.

Can I use homemade cookie butter?

Yes, homemade cookie butter made from crushed Biscoff cookies can be used. Ensure it has a smooth, spreadable consistency similar to the store-bought version.

How do I make the cake more moist?

Adding a bit of sour cream or yogurt to the batter can help increase the moisture content. Also, avoid overbaking the cake.

Can I use a different size cake pan?

You can use two 9-inch pans instead of three 8-inch ones, but baking times will vary. Check for doneness using a toothpick inserted into the center.

Is this cake overly sweet?

While the cake is sweet due to the cookie butter and frosting, the slightly spiced flavor of Biscoff balances it well. You can adjust the sweetness by reducing the powdered sugar in the frosting.

Can this recipe be made gluten-free?

Yes, substitute the flour with a gluten-free baking blend. Also, ensure your cookie butter and Biscoff cookies are labeled gluten-free.

Can I frost the cake with a different type of frosting?

Absolutely. Cream cheese frosting, whipped cream frosting, or even chocolate ganache work well with Biscoff flavors.

What’s the best way to crush Biscoff cookies for garnish?

Place the cookies in a zip-top bag and use a rolling pin to crush them. For a finer texture, pulse them in a food processor.

Should I refrigerate the frosted cake?

Yes, due to the butter-based frosting, it’s best to refrigerate the cake if not serving within a few hours. Bring it to room temperature before serving for the best texture and flavor.
