This show stopping holiday dessert is actually easy to make. Homemade cake batter has pumpkin puree added to it before baking in 3 pans. While the cake layers are cooling frosting is made that has been flavored with vanilla and cinnamon. A streusel mixture is baked in the oven. When assembling each layer has some streusel pressed on top of the frosting. Extra streusel is sprinkled on top of the finished cake.
Add the cinnamon, vanilla extract, milk and mix until well combined and smooth. Slowly add the remaining 6 cups of powdered sugar and mix until well combined and smooth.
The original recipe calls for melted butter in the streusel. DON’T melt the butter for the streusel, when I did this I had a solid piece after baking that was too hard to break and would have broken a tooth if someone tried to bite into it. Cut in room temperature butter with the rest of the ingredients, and then bake.
