Light and fluffy vanilla cake layers absolutely loaded with chopped-up biscoff cookies baked to golden delicious cake perfection. The smell alone of these cake layers will have you drooling. Paired with a whipped biscoff cookie buttercream frosting so light, airy, and wonderfully scrumptious that you'll be tempted to eat it straight from the spatula. And a dollop (maybe two) of cookie butter sandwiched between each velvet layer of biscoff cake. Start to finish and top the bottom, this dairy-free biscoff cookie butter cake is perfection.
