How to Make Moist Biscoff Cake Slice

Now that you’ve rounded up all your ingredients, let’s dive into the step-by-step magic of creating this delicious Moist Biscoff Cake Slice. Cooking is all about enjoying the process, so let’s have some fun!

Step 1: Preheat Oven and Prepare Pans

First things first, preheat your oven to 350°F (180°C). In the meantime, grab those 8-inch cake pans. Grease them with some butter and line with parchment paper. This little trick will ensure your cake slides out effortlessly when it’s time to serve.

Step 2: Combine Dry Ingredients

In a large bowl, sift together your all-purpose flour, cornstarch, baking soda, baking powder, salt, and ground cinnamon. Mixing the dry ingredients first prevents any lumps and allows the flavors to mingle beautifully. Set this bowl aside for a moment.

Step 3: Cream Butter and Sugar

Now, in another large bowl, beat the unsalted butter and vegetable oil together with the light brown sugar. Use a hand mixer or stand mixer to whip this mixture until it becomes light and fluffy—about two minutes will do the trick. The air whipped into this mixture is vital for a light, airy cake!

Step 4: Mix in Eggs and Biscoff Spread

Time to add the magic! Toss in the eggs, one at a time, mixing thoroughly after each addition. This is where you should blend in the Biscoff spread and vanilla extract. The scent will whisk you away, and trust me, your batter will thank you later!

Step 5: Incorporate Dry Ingredients and Buttermilk

Here’s where those dry ingredients come back into play! Alternately fold in the dry mixture and the room temperature buttermilk, starting and ending with the dry mix. This careful folding ensures everything is just combined, keeping your cake soft and tender.

Step 6: Fold in Crushed Biscoff Cookies

Now, it’s time for the fun part! Gently fold in the crushed Biscoff cookies. These little bits will give your cake extra flavor and texture, making each bite a delightful surprise.

Step 7: Bake the Cake

Evenly divide your luscious batter between the prepared pans. Give them a gentle tap on the counter to release any air bubbles trapped inside. Bake those beauties for 37 to 40 minutes. A toothpick should come out clean from the center—this indicates your cake is perfectly done!

Step 8: Cool the Cake Properly

Once baked, let the cakes cool in their pans for about 20 minutes. Then, carefully transfer them to a wire rack to cool completely. This step is essential to prevent sogginess and ensure a fluffy texture!

Step 9: Prepare the Frosting

As your cake cools, let’s whip up the frosting. Crush the remaining Biscoff cookies into fine crumbs. In a mixing bowl, beat the unsalted butter, powdered sugar, vanilla, and a hint of salt on low speed. Gradually increase the speed and whip for about 10 minutes, until you achieve a light, airy consistency. Now fold in the Biscoff spread and cookie crumbs for extra yumminess!

Step 10: Assemble and Decorate

Finally, it’s time for assembly! Level off the tops of your cakes, layering them with that delightful frosting. Spread it between the layers, on top, and sides for an indulgent finish. Feel free to garnish with extra Biscoff cookies and, if you’re feeling fancy, drizzle some additional Biscoff spread on top. Voilà, your Moist Biscoff Cake Slice is now stunningly complete!

Tips for Success

Always use room temperature ingredients for a smoother mix.
Don’t overmix the batter; mix just until combined for a fluffy texture.
Let the baked cakes cool completely before frosting; this prevents melting.
For extra flavor, try adding a hint of nutmeg or ginger to the batter.
Use a cake leveler for even layers, ensuring a professional look.

Equipment Needed

Mixing bowls: Have a couple on hand, or use any large bowls you have.
Hand mixer or stand mixer: A whisk works in a pinch, but mixers save time.
Measuring cups and spoons: If you don’t have these, make use of a kitchen scale.
8-inch cake pans: Round or square, just ensure they’re the same size for even baking.
Parchment paper: If unavailable, grease your pans generously to prevent sticking.

Variations

Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free blend for a gluten-free version of Moist Biscoff Cake Slice.
Dairy-Free: Use plant-based butter and almond or oat milk instead of buttermilk to make this cake dairy-free.
Chocolate Lovers: Add a cup of semi-sweet chocolate chips to the batter for an extra chocolatey experience.
Nutty Twist: Fold in a cup of chopped walnuts or pecans for added texture and flavor.
Spiced Variation: Enhance the spice level by adding a teaspoon of ground ginger or cardamom to the dry ingredients.

Enjoy it alongside a rich cup of coffee or a comforting tea for the perfect afternoon pick-me-up.
