This cinnamon marble cake is so yummy and so easy! If you're in need of a quick cake for a book party or shower but don't have time to make one from scratch, don't fear. This is your answer! And shhh... I won't tell them you used a box!
1/3 cup sugar
1 tablespoon cinnamon
1 box Golden Butter Cake mix
1 box instant vanilla pudding
1 cup sour cream
1 teaspoon vanilla
1/4 cup cooking oil
3/4 cup water
Preheat oven to 350 degrees Fahrenheit. In a separate bowl, combine 1/3 cup sugar and 1 tablespoon cinnamon. Mix well.
Grease pan and "flour" with 1/2 of the cinnamon/sugar mixture. To do this, you will spray the pan and sprinkle half of the mixture in the pan. Then, while gently tapping the pan (which helps loosen any excess), rotate the cinnamon/sugar mixture around the pan until it all sticks.
In a mixer, combine cake mix, vanilla pudding, sour cream, vanilla, eggs, and oil. Add water a little at a time until it's all mixed well.
Pour half of the cake batter into the pan. Sprinkle the remaining cinnamon/sugar mixture on top of the cake batter and top it off with the remaining batter.
Using a knife, swirl through the cake mixture. (I only go around the cake one or two times. Too many and you'll lose the "swirl" and have a blob.)
Bake for 30 to 40 minutes at 350 degrees F until cake is set. Allow cake to cool in pan for 20 minutes. Then, flip it onto a cooling rack lined with wax paper. Allow to cool for 30 minutes.
If you like, gently sift powdered sugar on top of the cake.
Cut and serve. It's an incredibly moist, dense cake. It's perfect by itself or served with some berries and whipped cream.
