Instructions

Step 1: Make the Cake Layers

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease and line three 8-inch round cake pans with parchment paper.
  2. Combine Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, cinnamon, and salt.
  3. Cream Butter and Wet Ingredients: Add the butter to the dry ingredients and mix on low speed until crumbly. Gradually add the egg whites, buttermilk, vegetable oil, and vanilla extract. Mix until just combined, being careful not to overmix.
  4. Divide and Bake: Divide the batter evenly among the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
  5. Cool the Cakes: Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

Step 2: Make the Vanilla Buttercream

  1. Cream Butter: In a large mixing bowl, beat the butter on medium-high speed until creamy and light.
  2. Add Vanilla and Salt: Mix in the vanilla extract and salt.
  3. Incorporate Powdered Sugar: Gradually add the powdered sugar, mixing on low speed. Once combined, increase the speed and beat until fluffy.
  4. Adjust Consistency: Add the heavy cream, one tablespoon at a time, until the frosting reaches your desired consistency.

Step 3: Prepare the Cookie Butter Buttercream

  1. Combine: Add the cookie butter and heavy cream to the prepared vanilla buttercream. Beat until smooth and evenly incorporated.

Step 4: Assemble the Cake

  1. Layer the Cake: Place one cake layer on a serving plate. Spread a layer of cookie butter buttercream over the top, followed by a drizzle of warmed cookie butter. Sprinkle with Biscoff cookie pieces.
  2. Repeat: Add the second cake layer and repeat the process.
  3. Top Layer: Place the final cake layer on top and cover the entire cake with a thin crumb coat of buttercream. Chill for 20 minutes.

Step 5: Decorate

  1. Frost the Cake: Apply a smooth final layer of buttercream to the chilled cake.
  2. Pipe Decorations: Use a piping bag fitted with a French tip to pipe decorative swirls around the edges of the cake.
  3. Drizzle and Garnish: Drizzle warmed cookie butter over the top and sides of the cake. Sprinkle with more Biscoff cookie crumbles for a finishing touch.
