Old Fashioned Coffee Cake

Many thanks to Flour Child for this amazing coffee cake recipe.
Go take a look at her HOME BAKED SWEETNESS.
Every time I see her blog I am tempted to bake! Yesterday I saw this and could not resist. I did not have cake flour on hand today so I used 2 cups all-purpose flour. I added a teaspoon of cinnamon to each the cake batter and the topping mix. (we love cinnamon) I also omitted the nuts for the children and because then I am not apt to eat the whole cake myself. This is a de-lish ...top of the stack for good standby recipes.
