This semi-homemade cake is super easy to make and is perfect for your Thanksgiving or Christmas celebrations. Each bite is sweet, soft and moist with layers of cinnamon buttercream and swirls of cinnamon sugar.
Preheat oven to 350°F. Lightly grease three 8-inch cake pans.
In a large mixing bowl, combine the 2 cake mixes, milk, melted butter and eggs. Whisk until all smooth and combined.
Divide the cake batter evenly between the three pans.
Mix the browns sugar and cinnamon together. Sprinkle the cinnamon sugar across the top of the cakes and swirl through.
Bake at 350°F for 20 to 25 minutes or until a toothpick inserted comes out clean.
Let the cakes cool in the pans for 5 minutes before transferring from pans to a cooling rack. Cool completely.
Buttercream
In a large mixing bowl, beat the butter, cream cheese, brown sugar and cinnamon together with a hand mixer until light and fluffy.
Add the powdered sugar a little at a time to the mixing bowl.
Whip the frosting with an electric mixer until light and fluffy (about 5 to 7 minutes).
Assembly
Place a cake layer onto a serving plate or cake plate.
Frost the top of the cake with a layer of cinnamon buttercream.
Repeat with the next layer.
Place the final layer on top and frost the whole cake with the cinnamon buttercream. If you like, you can reserve some frosting and pipe a bit on the top and sides for decoration.
Mix the sugar and cinnamon (listed in the topping section) and sprinkle all over the top. Decorate with cinnamon cereal if desired.
