Preheat oven to 375. In a large mixing bowl whisk together: flour, sugar, baking soda, salt, and cinnamon; set aside.

Melt butter in a saucepan then stir in applesauce, cocoa powder, and water and bring mixture to a boil, whisking constan. Pour hot butter mixture into flour mixture and stir. Add in buttermilk, eggs, and vanilla and whisk mixture until well combined. Pour mixture into a greased 9x13 baking dish and bake for 25-28 minutes or until toothpick inserted in center comes out with a few moist crumbs. Prepare frosting during last 5 minutes of baking.

For frosting: in a medium saucepan combine butter and cocoa powder and bring mixture just to a boil, stirring constantly to break up cocoa powder. Remove from heat. Pour mixture into a stand mixer (or use a hand mixer), add milk, powdered sugar, and vanilla and beat on low speed until well blended. Immediately spread over hot cake before frosting begins to cool. Also, if using, add sprinkles quickly before frosting sets.
