HOW TO MAKE IT :
CAKE
- Preheat oven to 350°F and spray two 9-inch round cake pans with nonstick cooking spray. Set aside.
- In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
- In a large bowl using a handheld mixer or stand mixer with a paddle attachment, cream together the butter and sugar until light and fluffy and lighter in color.
- Slowly add buttermilk, eggs, and vanilla.
- Add the dry ingredients, ½ cup at a time, to the wet ingredients in your mixer bowl until incorporated, about 2 minutes.
- Evenly divide the cake batter between the prepared cake pans (about 2 cups per pan).
- Bake for 30-35 minutes or until a toothpick inserted into the cakes comes out clean.
- Let cakes cool for about 10 minutes in the pans before transferring them to a wire rack to cool completely.
FILLING
- In a large bowl using a handheld mixer or a stand mixer with a paddle attachment, cream together the butter and Biscoff spread until smooth and fluffy (about 4 minutes).
- Slowly add 2 cups of confectioners’ sugar.
- Pour in heavy cream (or milk) and add vanilla.
- Gradually incorporate the remaining 2 cups of the confectioners’ sugar. Mix on low speed until all the ingredients are smooth and mixed well.
ASSEMBLING THE CAKE
- Level the cooled cake rounds and place the bottom layer on a cake stand or large plate.
- Spread the filling over the cake. (It will be a thick layer.)
- Top with the second cake round. Place the cake in the refrigerator to chill for 1-2 hours.
GLAZE
- After the cake has chilled, make the glaze. In a saucepan over medium heat combine the condensed milk, chocolate chips, and Biscoff spread.
- Stir constantly until the chocolate chips are melted and the mixture is smooth. Do not allow to come to a boil.
- Remove from heat and stir in vanilla.
- Pour the glaze over the top of the chilled cake, letting it run down over the sides. Cut and serve.
