Next, I add in the eggs one at a time, mixing well after each addition, followed by the vanilla extract. The mixture is looking so creamy and dreamy! I then alternate adding the dry ingredients and buttermilk into the bowl, beginning and ending with the dry ingredients. This method helps keep everything beautifully blended without overmixing, which can lead to a dense cake. Once it’s all combined, I divide the batter evenly between my prepared cake pans and smooth the tops.
I bake the cakes in my preheated oven for about 25-30 minutes, or until a toothpick poked in the center comes out clean. While they’re baking, my kitchen fills with the most wonderful scent of warm spices and caramel! Once done, I remove the cakes from the oven and let them cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely.
Once my cakes are completely cool, it’s time to whip up that delicious frosting! I beat together some softened butter, Biscoff cookie butter, and powdered sugar until fluffy, adding a splash of milk to reach my desired consistency. Frosting a cake has always been my favorite part! I apply a generous layer of frosting between the cake layers and then cover the entire cake with the remaining frosting. Finally, I sprinkle the crushed Biscoff cookies on top for that extra crunch and visual appeal.
Pro Tips for Best Results
After baking this cake multiple times, I’ve learned that using room temperature ingredients is key. It helps the batter mix together beautifully and produces a wonderfully airy texture. I usually take the eggs and buttermilk out of the fridge an hour before I start baking, making a big difference in the outcome.
Also, if you want to take it up a notch, don’t hesitate to drizzle some melted Biscoff cookie butter over the top right before serving. Not only does it add an extra layer of flavor, but it also looks absolutely fabulous.
Finally, when crushing your Biscoff cookies for the topping, I find that pulsing them in a food processor works wonders. It brings them to a fine crumb without making a mess, and I love the uniform texture it gives. My kitchen might still be a bit of a wonderland after the baking, but it’s totally worth it!
Common Mistakes to Avoid
One thing I learned the hard way is to never open the oven door while the cake is baking—especially during the first 20 minutes. I can’t tell you how many times I’ve ruined a cake this way, as the sudden temperature change can cause it to collapse! If I’m really curious, I try to peek through the oven window instead.
