Ingredient Notes and Substitutions
Biscoff: You can find this near the peanut butter at the store. If you can't find Lotus Biscoff, you can also use Speculoos Spread from Trader Joe's which is the same thing.
Lotus Biscoff cookies: You can find them in the cookie aisle! You will use the cookie crumbs in between the layers for extra flavor and a crunch.
Whole milk: This ingredient keeps the layers super moist and gives them a rich flavor. I don't recommend using plant-based milk or the layers will be dry.
Sour cream: This ingredient keeps it moist for days! It can be substituted with full-fat plain Greek yogurt if needed.
Cake flour: For a tender and delicate crumb, this recipe is made using the reverse creaming method (like my mimosa cake and ding dong hostess cake). This requires low-protein flour and can not be substituted!

Line three 6-inch pans with parchment paper on the bottom and preheat the oven to 350 F/180 C.
Step 1: Mix the dry ingredients. In a stand mixing bowl, combine the dry ingredients. Then mix in the cubed butter and Biscoff on low speed until it resembles coarse sand.
Step 2: Mix in the wet ingredients. Mix in the sour cream and oil until combined, it should resemble a thick paste. This is normal!
Step 3: Finish the cake batter. Then stream in the milk, eggs, and vanilla extract. Mix until just combined.
You will need to scrape down the bowl with a spatula to ensure there are no thick areas of batter.
Step 4: Layer the Biscoff. Evenly spread half of the batter (about 1 ½ cups) into the prepared pans.
Drizzle some of the melted cookie butter over the batter. Then evenly spread the rest of the batter on top.
Step 5: Bake and cool! Bake the layers in the preheated oven.
Allow the pans to cool for 10 minutes on a wire rack, then remove them from the pans and let them cool completely.
Step 6: Make the cookie butter buttercream. In a stand mixing bowl, combine the butter, Biscoff, powdered sugar, heavy cream, and vanilla.
Mix on medium speed until super light and fluffy!
Step 7: Assemble! To assemble, cut each layer in half horizontally.
Alternate layering cookie crumbs, a drizzle of Biscoff spread, and buttercream in between each layer, with the last layer placed upside down so the top is flat.
Step 8: Decorate! Crumb coat the top and sides with an offset spatula, then chill it in the fridge until set. Once set, spread a thicker layer of buttercream over it.
Decorate the sides and top with melted cookie butter and Biscoff crumbs. Enjoy your cookie butter cake!
Tips for the Best Biscoff Cake
- Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
- Use room temperature ingredients: Using room temperature ingredients creates a smooth, fully blended batter that will result in a uniform texture and even baking.
Storage and Freezing
Store leftover slices wrapped in plastic wrap in the fridge for up to 5 days. To store it whole, keep it in an airtight container.
To freeze it for later, first, freeze it whole. Then cut it into slices and wrap them individually in plastic wrap. Store them in a freezer bag or airtight container for up to 1 month!
You can find it near the jams and peanut butter at the store. You can also order it online from Amazon! If you can't find Biscoff spread, Trader Joe's has a Speculoos spread that is the same thing!
Yes! Biscoff is the original brand.
It has a delicious spiced caramel and gingerbread flavor!
