The top is thickly covered with glossy caramel sauce that drips down the sides and pools onto the white plate beneath. Decorative swirls of the same caramel frosting sit on top, adding texture and height. Small caramel pieces are scattered around the base of the cake on the plate. The background shows a slightly blurred kitchen scene with warm lighting, resting on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 cups All-Purpose Flour (Can substitute with a gluten-free all-purpose blend)
2 teaspoons Baking Powder (Essential for cake rise)
1 teaspoon Baking Soda (Works alongside baking powder)
1 teaspoon Salt (A pinch can be omitted for low-sodium diets)
1 teaspoon Ground Cinnamon (Try nutmeg as a substitute for a different spice profile)
1 cup Unsalted Butter (Must be softened for better creaming)
1 cup Light Brown Sugar (Can replace with dark brown sugar for a richer flavor)
1 cup Granulated Sugar (Adjust based on sweetness preference)
3 Large Eggs (Egg replacer can be used for vegan versions)
2 teaspoons Vanilla Extract (Can substitute with almond extract)
1 cup Whole Milk (Options like almond milk or oat milk for dairy-free)
1 cup Sour Cream or Greek Yogurt (Substitute with dairy-free yogurt for vegan option)
1 cup Creamy Peanut Butter (Stick to a commercial brand for smooth frosting)
2 cups Powdered Sugar (Adjust based on desired sweetness and consistency)
1/4 cup Heavy Cream or Milk (Can substitute with coconut cream for non-dairy)
1/2 cup Biscoff Cookie Butter (Can swap with more peanut butter)
1 cup Biscoff Cookies (Any spiced cookie can be a substitute)

Instructions

Step 1: Preheat the oven to 350°F (175°C). Grease two 8-inch or 9-inch round cake pans generously and dust with flour to prevent sticking.
Step 2: In a mixing bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon. Set this dry mixture aside.
Step 3: Beat the softened unsalted butter, light brown sugar, and granulated sugar until light and fluffy. Add the eggs one at a time, then stir in the vanilla extract.
Step 4: In a separate bowl, combine the whole milk and sour cream or Greek yogurt.
Step 5: Gradually mix the dry ingredients into the butter and sugar mixture, alternating with the milk and sour cream mixture. Begin and end with the dry ingredients to maintain batter consistency.
Step 6: Divide the batter evenly between the prepared cake pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
Step 7: Allow the cakes to cool in their pans for 10 minutes, then transfer to wire racks to cool completely before frosting.
Step 8: To make the frosting, beat the creamy peanut butter and softened butter together until smooth. Gradually add powdered sugar and heavy cream, mixing until the frosting reaches your desired consistency.
Step 9: Spread frosting between the cake layers, then cover the top and sides of the cake evenly with frosting.
Step 10: Melt the Biscoff cookie butter and drizzle it generously over the frosted cake. Sprinkle crushed Biscoff cookies on top for added texture and flavor.

Tips & Variations

For a dairy-free cake, substitute almond or oat milk and use dairy-free yogurt in place of sour cream or Greek yogurt.
Swap ground cinnamon with nutmeg or pumpkin pie spice for a different warm spice profile.
Use dark brown sugar instead of light brown sugar for a deeper molasses flavor.
Try almond extract in place of vanilla for a subtle nutty twist.
Add chopped Biscoff cookies between layers for extra crunch inside the cake.

Storage

Store the cake covered in the refrigerator for up to 4 days to keep the frosting fresh. Let the cake sit at room temperature for about 30 minutes before serving for the best texture and flavor. Leftovers can be wrapped tightly and frozen for up to 2 months; thaw overnight in the fridge before enjoying.

How to Serve

A slice of three-layer cake sits on a white plate with delicate patterns. The bottom, middle, and top layers are all dense, crumbly brown cake with a slightly rough texture. Between the cake layers are two thick layers of smooth, light brown frosting. On top, the cake is covered with thick, glossy caramel sauce that drips down the sides over the frosting and cake. Five dollops of textured darker brown frosting decorate the top edge of the slice, resembling small rosettes. Extra small caramel candies are placed around the base of the slice on the plate. The setting features a softly blurred kitchen background with a white marbled texture surface beneath the plate. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make this cake vegan?

Yes, you can make the cake vegan by using egg replacers, dairy-free milk and yogurt, and ensuring the peanut butter and Biscoff cookie butter you choose are vegan-friendly.

What is the best way to crush Biscoff cookies for decorating?

Place the cookies in a sealed plastic bag and gently smash them with a rolling pin or the bottom of a heavy pan. Aim for small chunks rather than fine crumbs to add texture to your cake topping.
