Step‑by‑Step Instructions for Moist Biscoff Cake Slice
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (180°C). While the oven heats, prepare two 8-inch cake pans by greasing them thoroughly with butter or oil and lining the bottoms with parchment paper to ensure easy cake release. This step is essential for achieving that perfect Moist Biscoff Cake Slice.
Step 2: Mix Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, cornstarch, baking soda, baking powder, salt, and ground cinnamon. This helps to aerate the dry ingredients and ensures an even distribution of the leavening agents. Set this bowl aside while you move on to the next step.
Step 3: Cream Butter and Sugar
In another bowl, use an electric mixer to beat the unsalted butter and vegetable oil together with the light brown sugar. Continue mixing for about 3-5 minutes or until the mixture becomes light and fluffy—a sign that you’re on the right track to a deliciously moist Biscoff Cake Slice.
Step 4: Add Eggs
With the mixer on low speed, add eggs one at a time, ensuring each egg is fully incorporated before adding the next. Follow this by mixing in the Biscoff spread and vanilla extract. The mixture should appear smooth and creamy, bringing you a step closer to a delightful batter.
Step 5: Combine Mixtures
Gradually fold in the dry ingredients using a spatula, alternating with the room temperature buttermilk. Start and finish with the dry ingredients, mixing gently until just combined. Be cautious not to overmix; this will keep your Moist Biscoff Cake Slice light and airy.
Step 6: Incorporate Cookies
Once the batter is well mixed, gently fold in the crushed Biscoff cookies, ensuring they are evenly dispersed throughout the batter. This addition will provide delightful texture and bits of flavor in your cake. The batter should be thick and luscious at this point.
Step 7: Bake
Divide the cake batter evenly between the prepared pans. Tap each pan on the counter to release any air bubbles trapped inside. Bake in the preheated oven for 37-40 minutes, or until a toothpick inserted into the center comes out clean. The cakes should also be golden brown on the top.
Step 8: Cool
After baking, remove the pans from the oven and let them cool in the pans for about 20 minutes. Carefully transfer the cakes to a wire rack to cool completely. This step ensures that your Moist Biscoff Cake Slice maintains its texture and doesn’t become soggy from residual steam.
Step 9: Prepare Frosting
While the cakes are cooling, you can prepare the frosting. In a mixing bowl, whip the unsalted butter until creamy, then gradually add the powdered sugar, vanilla extract, and salt. Finally, mix in the Biscoff spread and crushed cookies until the frosting is light and airy.
Step 10: Assemble Cake
Once the cakes are completely cool, level the tops with a serrated knife if necessary. Place one layer on a serving platter, spread a layer of frosting on top, and then add the second cake layer. Finish by frosting the top and sides, and if desired, garnish with additional Biscoff cookies and spread for an extra touch.

Moist Biscoff Cake Slice Recipe FAQs
How do I choose ripe ingredients for my Moist Biscoff Cake Slice?
Absolutely! For the best results, use room temperature eggs so they mix well into the batter, ensuring a light and airy cake. When selecting buttermilk, check the expiration date, and if using regular milk with vinegar as a substitute, let it sit for about 5-10 minutes after mixing to mimic buttermilk’s tanginess.
What’s the best way to store my Biscoff Cake Slice?
You can store your Moist Biscoff Cake Slice in an airtight container at room temperature for up to 3 days. If you want to extend its freshness, wrap it well and refrigerate for up to 5 days. Keeping it stored properly preserves the cake’s delightful moisture and flavor, so don’t skip this step!
Can I freeze the Moist Biscoff Cake Slice?
Absolutely! To freeze, wrap each slice tightly in plastic wrap and then in aluminum foil. By doing this, you can keep it fresh for up to 3 months. When you’re ready to enjoy it again, simply thaw overnight in the refrigerator or microwave for a few seconds to restore its fresh-baked charm.
What should I do if my cake sinks in the middle?
Ah, don’t worry! This can happen if the batter is overmixed or the leavening agents aren’t fresh. To troubleshoot, ensure you’re using fresh baking powder and baking soda, and mix your dry and wet ingredients until just combined—no more! If your cake sinks, simply level it with a knife, and it will still taste delightful.
Are there any allergy considerations for this recipe?
Great question! The Moist Biscoff Cake Slice contains eggs, gluten (from the flour), and dairy (from the butter and buttermilk) which are common allergens.
