- Preheat your oven to 350°F (175°C) and prepare three 8-inch round cake pans by lining with parchment paper.

- Mix in unsalted butter until the mixture resembles coarse crumbs.
- Add egg whites, buttermilk, vegetable oil, and vanilla extract, and mix until just combined.
- Evenly divide the batter among prepared pans and bake for 33-35 minutes.
- Let the cake layers cool for about 10 minutes in the pans before transferring to a cooling rack.
Frosting and Assembly
- Cream room temperature butter until smooth, gradually adding powdered sugar and alternating with heavy whipping cream.
- Mix in cookie butter with half of the frosting until well combined.
- Assemble the cake by layering cake and cookie butter frosting, finishing with vanilla buttercream on the outside.
- Decorate with crushed Biscoff cookies and drizzled cookie butter.
