Moist Biscoff Cake Slice: Spiced Cookie Butter Layer Cake

Deep caramel tones and warm speculoos spices permeate every forkful of this moist layer cake frosted with whipped Biscoff buttercream and crowned with crunchy cookie crumbles. Born from beloved European spiced shortcrust biscuits, cookie butter brings complex notes of brown sugar, cinnamon, and nutmeg to traditional sponge cake. It produces a bakery-caliber centerpiece that enchants dessert enthusiasts.

Incorporating both unsalted butter and vegetable oil into the batter ensures rich dairy flavor alongside long-lasting moisture retention in the crumb. Room-temperature buttermilk reacts with baking soda to tenderize the gluten network, producing an airy, springy sponge. Beating creamy Biscoff spread directly into powdered sugar and butter yields a silky frosting that glides effortlessly over the cake layers.

Plate generous slices of Biscoff layer cake with a drizzle of warm melted cookie butter, a scoop of vanilla bean gelato, or a golden square of vegan lemon sheet cake for a bakery-inspired spread. Store remaining cake under a glass cake dome at cool room temperature for up to three days, or refrigerate covered for five days.

Notes

Cornstarch softens the protein structure of all-purpose flour, mimicking the delicate crumb of specialized cake flour.
