Indulge in a Cinnamon Roll Layer Cake!

Prepare Cake: Cream butter and sugar until fluffy. Add sour cream and vanilla extract, then beat in egg whites. In a separate bowl, whisk together flour, cinnamon, baking powder, and salt. Gradually add dry ingredients to the butter mixture, alternating with milk and water, beginning and ending with dry ingredients. Mix until just combined. Pour batter into prepared cake pans and bake according to instructions.

Frosting: In a large bowl, whip together butter, shortening, powdered sugar, vanilla extract, cinnamon, and milk until creamy and smooth.

Assembly: Once cakes are cooled, spread glaze over each layer. Then, frost each layer with cinnamon frosting. Stack the layers and finish with frosting on top and around the sides. Optionally, pipe decorations on top.

Treat yourself and your guests to this luxurious cake that's as much a feast for the eyes as it is for the palate!
