What Is Biscoff?
Biscoff, also known as cookie butter, is a smooth spread made from crushed Belgian speculoos cookies. It has a rich caramelized flavor with hints of cinnamon and warm spices. While Biscoff is the most popular brand, any cookie butter spread will work in this recipe.
For best results, Lotus Biscoff spread and cookies are used for both flavor consistency and decoration.
How to Make Biscoff Cake
This cake uses a carefully balanced combination of butter and oil, which gives you the best of both worlds: rich flavor from the butter and long-lasting moisture from the oil.
Key Baking Tips
- Measure flour accurately to avoid a dense or dry cake
- Alternate adding dry ingredients and buttermilk to prevent overmixing
- Mix gently once liquids are added to maintain a soft crumb
- Use parchment-lined pans so the delicate layers release easily
Cake strips are highly recommended to ensure flat layers that stack beautifully without trimming.
The Biscoff Buttercream Frosting
The frosting is an American-style buttercream made extra creamy with:
- Biscoff spread
- A small amount of cream cheese to balance sweetness
- Cinnamon to enhance the cookie’s natural spice
The result is a smooth, rich frosting that complements the cake without overpowering it.
Assembling the Cake
Once the cake layers are fully cooled:
- Level the tops if needed
- Spread a thin layer of frosting on the first layer
- Pipe a frosting border to hold the filling in place
- Fill the center with warmed Biscoff and crushed cookies
- Add the second layer and apply a crumb coat
- Chill briefly, then frost and decorate with extra cookie crumbs
This method ensures clean layers and a professional finish.
Pan Options & Variations
- Two 8-inch round pans: classic layered cake
- Two 9-inch pans: slightly shorter layers, reduced bake time
- 9×13 pan: perfect for sheet-cake style serving (halve frosting)
For an extra finishing touch, drizzle warm cookie butter over the top and sprinkle with crushed Lotus cookies.
Storage Tips
- Store the finished cake covered in the refrigerator for up to 4 days
- Cake layers can be baked one day ahead and stored tightly wrapped
- Assemble and frost on the day of serving for best texture
