One Box Yellow- I like Duncan Hines ~ Prepare cake mix as directed; pour into 3 eight inch round cake pans.
Bake for 15 minutes (cake will look wet).
While cakes are baking-prepare the following crumb mix by mixing the following ingredients until crumbly.
4 cups flour4 sticks of butter or margarine, softened
1 1/3 cup sugar
2 T. Cinnamon
1 T. Vanilla
Sprinkle the crumb mixture over the cakes once they are done the first 15 minutes and bake them another 17-20 minutes or until toothpick comes out clean.
Let cool completely and sprinkle with powdered sugar.
Note- You may want to make these in disposable pans as it is easier to give away and not have to ask for your good cake pans back.
