That warm, spiced aroma, familiar from those little airplane cookies, has always held a special place in my heart. When the idea struck to transform that beloved flavor into a full-fledged celebration, I knew I had to create the ultimate Biscoff cake.
I remember the first time I whipped up a test batch, the kitchen filling with that unmistakable scent. My partner walked in, stopped dead in his tracks, and declared it smelled like pure happiness, before he even saw the finished creation.
It’s truly a standout, much like that unforgettable mulberry cheesecake I shared a while back, but this one brings a unique kind of joy. I’m so excited for you to experience this magic yourself.
What You Need to Make This Recipe
For this incredible cake, a few ingredients truly shine and make all the difference. Of course, the star is the creamy Biscoff spread itself, which I use generously in both the cake layers and the utterly dreamy frosting, infusing every bite of this Biscoff cake with that distinctive caramelized spice. I also lean on good quality brown sugar to deepen that warm, molasses-like flavor, and a touch of buttermilk which is my secret for keeping the cake layers incredibly moist and tender, much like the layers in my favorite pineapple poke cake.

How to Make Biscoff cake
The journey to making this cake begins with gently creaming the butter and sugars until they’re light and fluffy, creating the perfect foundation for those tender layers. Then, we slowly incorporate the dry ingredients, alternating with the liquid, being careful not to overmix, which keeps the cake beautifully airy.
As the layers bake, your kitchen will fill with an absolutely intoxicating aroma – that deep, spiced Biscoff scent mixed with warm cake, reminiscent of baking a classic cinnamon roll poke cake. Once cooled, we create a truly decadent Biscoff cream cheese frosting that comes together like a dream, ready to crown our perfectly baked layers with its irresistible, smooth texture.
Pro Tips
Getting your Biscoff cake just right involves a few crucial details that elevate it from good to truly unforgettable. For instance, always ensure your butter and Biscoff spread are at perfect room temperature before you start on the frosting; this is key to avoiding lumps and achieving that silky-smooth consistency we crave.
When mixing your cake batter, mix until just combined, as overmixing can develop the gluten too much, leading to a denser, less tender crumb. Don’t rush the cooling process either; completely cooled cake layers prevent your beautiful frosting from melting right off.
My Secret Trick: I love to gently warm a small amount of extra Biscoff spread until it’s pourable, then drizzle it over the frosted cake for an extra layer of flavor and a gorgeous, glossy finish that makes every slice even more enticing.

How to Store Biscoff cake
- Store your Biscoff cake in an airtight container in the refrigerator for up to 3-4 days to keep it fresh and moist.
- For longer storage, individual slices or unfrosted layers can be wrapped tightly in plastic wrap and then foil, and frozen for up to 2 months.
- Thaw frozen cake overnight in the refrigerator before serving.
- If serving from the fridge, allow the cake to come to room temperature for about 30 minutes to an hour for the best flavor and texture.
Nutritional Benefits
While this delightful Biscoff cake is certainly a treat, it also brings a dose of joy and satisfaction, which I consider a major benefit! The spices like cinnamon and ginger, often found in Biscoff cookies, offer their own small contribution of antioxidants, making this indulgent dessert a moment of spiced comfort and pure delight.

FAQs
Can I make this cake ahead of time?
Absolutely! The cake layers can be baked a day or two in advance, wrapped well, and stored at room temperature. You can also prepare the frosting and keep it chilled in the refrigerator, ready to assemble the cake when you are.
What is the best way to incorporate the cookie butter?
Melting it gently ensures a smooth, even mix into both the batter and the dreamy frosting for this Biscoff cake. This step is crucial for achieving that consistent, irresistible flavor throughout your dessert.
Why is my frosting grainy?
A grainy frosting is often due to unsifted powdered sugar or ingredients that weren’t at room temperature. Make sure to sift your powdered sugar and let butter and Biscoff spread soften fully before mixing for a truly smooth result.
Can I substitute ingredients in the cake layers?
For best results, I always recommend sticking to the recipe as closely as possible, especially for baking. Substitutions can significantly alter the texture and flavor, particularly with specific ingredients like buttermilk.

Biscoff Cake
Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, or line them with parchment paper circles and spray with non-stick cooking spray.
- In a medium bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and 0.25 tsp of salt. Set aside.
- In a large bowl, using an electric mixer, cream together 0.5 cup room temperature unsalted butter until light and fluffy, about 2 minutes. Beat in the eggs one at a time, mixing well after each addition. Stir in 1 tsp vanilla extract and 0.25 cup Biscoff cookie butter until fully combined.
- Gradually add the dry ingredients to the wet ingredients, alternating with the whole milk, beginning and ending with the dry ingredients. Mix until just combined, being careful not to overmix. 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 inverting them onto a wire rack to cool completely.
- While the cakes cool, prepare the buttercream. In a large bowl, beat 1 cup room temperature unsalted butter with an electric mixer until light and fluffy, about 3-4 minutes. Gradually add the powdered sugar, one cup at a time, mixing on low speed until combined, then increasing to medium-high until smooth. Beat in 1 cup Biscoff cookie butter, 0.5 tsp vanilla extract, and the remaining 0.25 tsp salt. Add 2-3 tablespoons of heavy cream, one tablespoon at a time, until the buttercream reaches your desired consistency – it should be smooth and spreadable.
- Once the cakes are completely cool, use a serrated knife to level the tops if needed. Place one cake layer on your serving plate or stand. Spread about 0.75 cup of Biscoff 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 entire cake. Finish by gently pressing the crushed Biscoff cookies around the base and/or on top of the cake.
Notes
If your Biscoff cookie butter is very firm, you can gently warm it in the microwave for 15-20 seconds to make it more spreadable for both the cake batter and buttercream.
This cake can be stored at room temperature, covered, for up to 3 days, or refrigerated for up to 5 days. Bring to room temperature before serving for the best flavor and texture.
Conclusion
I truly hope you give this beautiful Biscoff cake a try and let that incredible spiced flavor whisk you away. It’s more than just a dessert; it’s a moment of pure comfort and indulgence that I know you’ll adore.
