Biscoff Buckeye Cake

It starts with the perfect chocolate cake in this recipe. Then, it’s all about the Biscoff spread used in both the filling and the glaze. It is a sweet and decadent chocolate dessert with the distinct flavor of Biscoff cookies in every bite.

What is a Buckeye Cake?

A Buckeye cake is named after the buckeye candy that is a peanut butter fudge dipped in chocolate. They are similar to peanut butter balls, but with the peanut butter still visible. So, a Buckeye cake is made with peanut butter in between the chocolate cake.

With Biscoff in the title of this cake, the filling is a smooth and creamy filling made with Biscoff spread (a cookie butter) instead of peanut butter. So, this is a wonderful and delicious alternative for someone who has a peanut allergy!

Biscoff Buckeye Cake Ingredients

There are three parts to this recipe–the chocolate cake, the filling, and the glaze. This recipe is from Katrina Bahl‘s book The Biscoff Cookie and Spread Cookbook.

Chocolate Cake: Room temperature ingredients (especially butter and eggs) are important when making the chocolate cake. I also used Dutch-processed cocoa powder and if you don’t have buttermilk, make your own homemade buttermilk.

Filling: Biscoff spread is used in both the filling and the glaze in this dessert. For the filling, I recommend using heavy cream, but you could get away with milk if that is all you have on hand.

Biscoff Spread: Biscoff spread is somewhat like peanut butter, but sweeter. If you have ever had the cookies on a Delta Airlines flight, you may have tried Biscoff cookies. Speculoos Cookie Butter can also be used since Biscoff cookies are speculoos cookies. The spread comes in chunky and creamy; I recommend the creamy variety for this recipe.

Glaze: Be sure to use sweetened condensed milk in the glaze. It can sometimes be confused with evaporated milk, which has no added sugar.

How to Make Chocolate Cake

The first step in this Biscoff Buckeye Cake is to make the chocolate cake. To make the cake, first, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set the dry ingredients aside.

Next, in the bowl of a stand mixer with the paddle attachment or using a handheld mixer, cream together the butter and sugar until light and fluffy. The color will also get a little lighter as you are creaming the ingredients. Then, slowly add the buttermilk, eggs, and vanilla.

Add 1/2 cup of the dry ingredients at a time to the wet ingredients, mixing until incorporated. Divide the batter evenly between 2, 9-inch round cake pans. This ends up being about 2 cups of batter per pan. Bake the cakes for 30-35 minutes, or until a toothpick comes out with a few crumbs, but no wet batter.

Let the cakes cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely. When they are almost cool, make the filling.

How to Make the Filling

This creamy and delicious filling is the star of this dessert. To make the filling, first, cream the butter and Biscoff spread until smooth and fluffy. Slowly add 2 cups of the confectioners’ sugar, followed by pouring in the heavy cream and adding vanilla.

Finally, gradually incorporate the remaining 2 cups of confectioners’ sugar and mix on low until the filling is smooth and all the ingredients are mixed well.

Assembling the Biscoff Buckeye Cake

This cake does need to chill for at least an hour (I recommend two hours) before adding the glaze. To assemble the cake, level the two layers of chocolate cake and place one round on a cake stand or a large plate. (Here are some tricks to bake a level cake.) Spread the Biscoff filling on top of the cake. It will be thick! Then, top with the second cake round and place in the refrigerator for a couple of hours.

How to Make the Glaze

After the cake has had time to chill, make the Biscoff spread glaze. To make the glaze, first, in a saucepan over medium heat, combine the condensed milk, chocolate chips, and Biscoff spread. Stir constantly until the chocolate chips have melted and the mixture is smooth. Do not let the mixture come to a boil.

Remove the saucepan from the heat and stir in the vanilla. Pour the glaze over the chilled cake, letting the glaze run down the sides of the cake. Cut into it and enjoy! Store leftovers, covered, in the refrigerator.
