Step‑by‑Step Instructions for Moist Biscoff Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 180°C (350°F). While the oven warms up, take two 8-inch cake tins and generously grease them with butter or non-stick spray. For easier removal later, line the bottom of each tin with parchment paper, giving you a great start for your Moist Biscoff Cake.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, cornstarch, baking soda, baking powder, salt, and ground cinnamon. This not only ensures that there are no lumps but also helps to incorporate air for a fluffy texture. Once combined, set this dry mixture aside while you focus on the wet ingredients for your cake.
Step 3: Cream Butter and Sugar
In another large mixing bowl, add the room temperature unsalted butter, vegetable oil, and light brown sugar. Using an electric mixer, beat the mixture on medium speed for about 2 minutes, or until it’s light and creamy. This step is crucial as it introduces air into the mixture, ensuring your Moist Biscoff Cake is perfectly fluffy.
Step 4: Incorporate Eggs and Flavors
One at a time, add three large eggs to the butter-sugar mixture, mixing well after each addition until fully incorporated. Then, blend in the Biscoff spread and vanilla extract, ensuring that everything is combined smoothly. This infusion of flavors is what makes your cake undeniably delicious.
Step 5: Fold in Dry Ingredients
Gradually add the dry ingredients to the wet mix, alternating with the buttermilk. Start and finish with the flour mixture, gently folding everything together until just combined. Be mindful not to overmix, as this could affect the cake’s texture—a tender crumb is what we’re aiming for in the Moist Biscoff Cake.
Step 6: Add Crushed Biscoff Cookies
Once the batter is well combined, gently fold in the crushed Biscoff cookies. This will add delightful texture and contribute to the signature flavor of your cake. Make sure the cookies are evenly distributed throughout the batter for that extra delicious bite in every slice.
Step 7: Bake the Cake
Divide the batter evenly between the prepared cake tins. Tap each tin gently on the counter to release any trapped air bubbles. Place them in the oven and bake for 37 to 40 minutes, or until a toothpick inserted into the center comes out clean. Your kitchen will soon be filled with an irresistible aroma!
Step 8: Cool the Cakes
After baking, let the cakes cool in their pans for about 20 minutes. Carefully turn them out onto a wire rack to cool completely. Ensuring the cakes are cool is vital, as it prevents the buttercream frosting from melting when you frost your Moist Biscoff Cake.
Step 9: Prepare the Frosting
For the frosting, blend the remaining crushed Biscoff cookies into fine crumbs. In a mixing bowl, beat the softened butter with powdered sugar, vanilla extract, and a splash of milk on low speed until combined. Then, whip the mixture on high for about 10 minutes until fluffy and creamy, adding more milk if needed for the desired consistency.
Step 10: Frost the Cake
Once the cakes are completely cooled, level them with a knife if necessary. Spread a layer of buttercream between the two cake layers, then frost the top and sides of the cake with the remaining frosting. For an extra touch, decorate with whole Biscoff cookies and drizzle additional Biscoff spread on top before serving your delightful Moist Biscoff Cake.

Make Ahead Options

When you’re ready to enjoy your creation, let the cakes come to room temperature, frost them, and decorate just before serving for a delightful, fresh-tasting dessert!
