Cinnamon Coffee Cake I

This recipe is based off CM's Cinnamon Coffee Cake recipe on the Cooks dot com website. However, I made some slight modifications. Here is how I made mine:

Cake:

1 cup all purpose flour

1/2 cup wheat flour
2 1/2 tsp. baking powder
1/2 tsp. salt
1/2 cup sugar

1/4 tsp cinnamon
1 egg
1/4 cup vegetable oil
3/4 cup milk

Cinnamon Crumb Topping:

1/3 cup all purpose flour
1/2 cup sugar
1/4 cup butter, softened
3/4 teaspoon cinnamon

Steps:

1. Preheat oven to 375°F.
2. Combine dry ingredients for cake. Beat together egg, oil and milk, then add to dry ingredients - add half, combine, then add the second half.
3. Brush a 9-inch circular cake pan with butter. Dust the pan with flour and tap out the excess. Fill pan with cake batter and level off top with a spatula. Next, spread the Cinnamon Crumb Topping over top of cake and bake.
4. Bake for 20-25 minutes.

My Notes:

Cake came out a little dry but otherwise fine. Took it 23 mins to bake. Had to invert cake pan, press it to cake stand, and tap it to release the cake.
