This biscoff cake has lotus biscoff cookies baked right into each layer, paired with a delicious biscoff buttercream. It's easy to make and has notes of vanilla, brown sugar, and cinnamon! It's every cookie butter lover's dream!
In my opinion, Biscoff spread is truly one of the greatest spreads ever created (yes - even better than peanut butter!). I love using it in brownies, cookies, and cupcakes - it pairs so well with chocolate or vanilla flavors!
This lotus biscoff cake is a truly indulgent dessert. It combines crunchy biscoff cookies, creamy biscoff spread, and a fluffy vanilla layer cake.
If you haven't tried cookie butter yet - oh my goodness words can not describe it!
Why You'll Love This Biscoff Cake
- It's got all the delicious brown sugar and spiced flavors of biscoff and uses both biscoff spread and lotus biscoff cookies.
- The light and fluffy vanilla cake only uses 1 cup of sugar, which means it isn't too sweet and balances out the biscoff buttercream perfectly.
- You can easily adapt the biscoff cake recipe to fit different pan sizes (the instructions are further down in the post).
- Biscoff cookies are layered on the cake for a wonderful texture combination that goes so well with the cake and adds in tons of biscoff flavor!
- Milk: You can use regular milk or you can make this biscoff cake dairy free and use your preferred dairy free milk.
- Oil: this cake uses canola oil instead of butter which is key to a fluffy, light crumb. You can also use sunflower oil or other neutral vegetable oil.
- Butter: You can use regular salted butter, or dairy free butter.
- Flour: This recipe uses all-purpose flour, and in order to get a fluffy vanilla cake, I recommend using a kitchen scale to measure your flour. Measuring with a cup can lead to too much flour, which can make the cake dry and dense.
- Biscoff spread (cookie butter): You can use any brand of cookie butter, some places like Trader Joe's or President's Choice make their own brands, and they are all delicious. It can often be found under the name "Speculoos" spread. I recommend the smooth variety but you can also use crunchy!
- Biscoff cookies: You can use any brand of speculoos style cookie, and you can layer both cakes or just add the cookies to one layer - it's up to you!
Step By Step Instructions
Note: Full ingredient measurements and instructions can be found in the recipe card at the bottom of this page.
Step One: Preheat the oven to 350°F. Prepare two 8 inch round cake pans. Spray the inside with cooking spray, then cut round pieces of parchment paper so that they fit in the bottom of each pan. Set the pans aside.
Step Two: In a large bowl, whisk together flour, salt, and baking powder together.
Step Four: Alternate pouring the dry ingredients into the bowl, then pour in the milk. Repeat, mixing between additions and alternating wet and dry until the final specks of flour are gone.
Step Five: Layer biscoff cookies along the bottom of the pan, then pour the batter evenly between the cake pans. *Note that in the video for this post I added cookies on top of the batter. You can do this as well, but if you plan to shave off the top domed part of your cakes before stacking them, it's easier to add the cookies to the pan before the batter.*
Bake for 23-30 minutes, or until a toothpick inserted in the middle of the cakes comes out clean. Let the cakes cool in the pans then remove them from the pans upside down onto a cooling rack.
Step Six: Make the buttercream. In the bowl of a standing mixer or handheld mixer, beat butter and biscoff spread until smooth. Add salt. Slowly add in the powdered sugar, until desired consistency is reached.
Add a little bit of milk to thin out the buttercream if needed.
Step Seven: Once the cakes have cooled, place one of the cakes on a cake plate or stand, with the biscoff cookie side down. You may want to shave the tops of the cake off to get rid of the domes, but that's up to you.
Add a few scoops of buttercream on top and spread it in an even layer, leaving around 1 inch of room around the edges. Place the second cake on top, again with the biscoff cookie side down.
Scoop more buttercream on top of the cake and smooth it out evenly, repeating around the sides of the cake if desired. Melt biscoff and pour it around the edges of the cake, add crushed biscoff cookies on top, and/or pipe more buttercream on top of the cake to decorate the cake to your taste!
FAQs and Expert Tips
Biscoff is dairy free, egg free, and vegan, but you should always read the labels as this may vary from one brand to the next, or depending where you live.
I haven't tested this cake without eggs, and they are crucial to the structure of this cake recipe so I don't recommend it.
However, if you have a favorite recipe for a vegan vanilla cake you can use that as the cake base and add the cookie layer and biscoff layer to it!
This cake itself doesn't have biscoff in it. It is a simple vanilla cake recipe, paired with the biscoff cookies and biscoff buttercream.
I tested this cake multiple times with biscoff in the actual cake batter, but it made the cake very dense and sweet!
The options are endless! Here are a few ideas:
1. Melt biscoff cookie butter over the stove or in the microwave and drip it down the top and sides of the cake
2. Pipe frosting on top and stick biscoff cookies into the piped frosting
3. Frost the middle of the cake and the top of the cake only and sprinkle with crushed up biscoff cookies
4. Cover the cake with buttercream, then press biscoff cookies into the side of the cake all the way around
5. Get creative! There are so many fun ways to decorate a biscoff cake!
Is this cake very sweet?
Biscoff spread is quite sweet, so this cake recipe was purposely developed to be less sweet.
One way to reduce the sweetness is to assemble this cake with biscoff buttercream in between the cake layers and on top, but not on the sides. When I make this cake for myself I often do that. You won't need as much buttercream if omitting it from the sides.
Can I make this a biscoff chocolate cake?
Sure! The flavors of biscoff go great with chocolate! If you want to use a chocolate cake instead of vanilla, use this chocolate cake recipe (it can be made with regular ingredients if you don't follow a dairy free diet).
Then, simply layer the cookies on top and follow the instructions for the biscoff buttercream.
Can I make this as Biscoff cupcakes?
You're in luck - here is a delicious Biscoff cupcake recipe!
Can I make this cake using different cake pans?
Sure! Instructions for different sizes of cake pans can be found in the Notes section of the recipe card at the bottom of this page.
- As always, my number one tip is to properly measure your flour! The biscoff cake texture will not be as light and fluffy and the cake could turn out dry or dense if you over-measure your flour. I recommend a $10 kitchen scale to weigh your flour.
- Don't skip the parchment paper lining in your cake pans! The cakes could break when you try taking them out of the pan if you skip the parchment paper layer.
- Do not over-mix! This can lead to a dense cake texture. Alternate the milk and dry ingredients and gently mixing until all dry ingredients are just incorporated.
- Adjust powdered sugar (confectioner's sugar) or add milk to achieve the perfect buttercream consistency. If the buttercream seems too thin, you can add a little more powdered sugar, about ¼ cup at a time. If it seems too thick, add ½ tablespoon of milk at a time until your desired consistency is reached.
Storage and Freezing Instructions
The cake can be stored covered at room temperature for 3-4 days. I store mine in a cake carrier. The cookie layer will get less crunchy over time, and will soften quite a bit, so the cake is best served within 1-2 days of being baked.
To freeze the cooled cake layers, tightly wrap them in plastic wrap, then aluminium foil. Freeze in ziploc bags for up to 3 months, then let thaw at room temperature.
Leftover buttercream can be stored in an airtight container in the freezer for up to 2 months, then thawed in the fridge. When ready to use it, you can mix it up using a handheld or standing mixer to make it fluffy again.

- 2½-3 cups powdered sugar (icing/confectioner's sugar)
- ⅛ teaspoon salt
- Preheat the oven to 350°F and prepare two 8 inch round cake pans. Spray the inside with cooking spray, then cut round pieces of parchment paper so that they fit in the bottom of each pan (do not skip the parchment paper lining!)
- Whisk flour, salt, and baking powder, together in a medium bowl and set aside.
- Alternate pouring the dry ingredients into the bowl, then pour in the milk. Repeat, mixing between additions and alternating wet and dry until the final specks of flour are gone.
- Layer Biscoff cookies on the bottom of your cake pans, then pour cake batter into the pans, dividing it evenly between the two pans. *Note that in the video for this post I added cookies on top of the batter. You can do this as well, but if you plan to shave off the top domed part of your cakes before stacking them, it's easier to add the cookies to the pan before the batter.*
- Bake on the middle rack of the oven for 23-30 minutes or until a toothpick inserted in the middle of the cakes comes out clean.
- Let the cakes cool in the pans for 20 minutes, then run a butter knife around the outside of the cake to loosen it from the pan and flip upside down onto a cooling rack to cool completely. This helps to flatten the top of the cakes.
- Add in the vanilla extract, then add the salt and icing sugar, ¼ cup at a time until desired consistency is reached. If the buttercream is too thick, add in milk 1 tablespoon at a time to thin it out to the consistency you want. If it's too thin, add in more confectioner's sugar (powdered sugar) ¼ cup at a time.
