Mini Cinnamon Bundt Cakes

My darling friend Jenny gave me a mini-bundt pan for my birthday. I've been having fun adapting down recipes for full size bundt cakes. This recipe will work big or small. 1 yellow cake mix
1 small vanilla pudding
3/4 c. oil
3/4 c.water
4 eggs
1 tsp. vanilla
1/4 c. sugar
1 1/4 tsp. cinnamon
powdered sugar and milk for glaze

Mix cake mix, pudding, oil, water and vanilla. Beat in eggs, one at a time until smooth. In a separate bowl mix cinnamon and sugar. Pour half of batter in a greased bundt pan (or in mini bundt pans). Sprinkle cinnamon sugar all over the top of the batter. Pour the rest of the batter on top of the cinnamon sugar. Bake at 350 degrees for about 40-50 minutes or until a toothpick inserted in center comes out clean. Cool and then invert cake onto a serving dish. Mix 1 cup powdered sugar and 2 T. milk and 1 tsp. vanilla. Stir until mixture forms a smooth glaze (may need to add a little more milk if it's too thick). Drizzle over cake.
