Biscoff Layer Cake is the ultimate cake for Biscoff/speculoos lovers. The light and moist vanilla genoise cake is layered with Biscoff spread, Biscoff cookies, and Biscoff whipping cream. A perfect Biscoff indulgence to satisfy your sweet craving.
In a small bowl, combine sugar and hot water. Stir until the sugar is dissolved. Cool completely before using.
Biscoff Cream
In a heatproof bowl, add the water and sprinkle the gelatin powder on top. Allow to sit for 5 minutes. Heat in the microwave or over a stovetop until the gelatin is fully dissolved. Set aside. (This step is optional. the gelatin makes the cream sturdier.)
In a large bowl using a handheld or stand mixer fitted with a whisk attachment, combine the heavy whipping cream, confectioners' sugar, and vanilla extract. Whip until the mixture starts to thicken and stiff peaks form, then turn the mixer to low speed.
Slowly pour in the gelatin mixture until well combined. Increase the mixer to medium speed and continue mixing until stiff peaks form.
Add the Biscoff spread into the cream. Whip the cream again until well combined. Refrigerate the cream until you use it.
Assemble
Cut the genoise cake horizontally into 3 even thin layers.
Place the bottom cake layer on your cake stand or serving plate. Brush the simple syrup on top.
Spread 1/4 cup Biscoff spread evenly, then place 6 Biscoff cookies layer on top. Spread the Biscoff cream on top and level the top with a spatula.
Place another cake layer on top. Work on the second layer by brushing the simple syrup, spreading 1/4 cup Biscoff spread, placing 6 Biscoff cookies, and spreading the Biscoff cream again.
Place the final cake layer on top. Brush with simple syrup. Cover the top and sides of the cake with more Biscoff cream.
Topping
In a food processor, blend 5 Biscoff cookies until finely ground.
Cover the top of the cake with grounded Biscoff cookies. Add a dollop of the Biscoff cream in the middle of the cake and place one Biscoff cookie over it.
