Each of my boys fixes dinner once a week. I let them choose what to fix and they usually only make the main course so it is always good if the main course is a complete meal. Coffee cake does not qualify as a complete meal so I added some fruit and a salad to go with it. Here is the recipe he used:
Breakfast Cake
cake:
1/2 cup shortening or butter
2 1/2 cups flour
3/4 cup sugar
2 Tbsp. baking powder
pinch of salt
1 1/3 cups milk
2 eggs
Cut shortening into flour. Add remaining dry ingredients and mix. Add wet ingredients and mix by hand. Pour into a greased 9x13" pan.
topping:
1/2 cup flour
3/4 cup sugar
4 1/2 Tbsp. butter, softened
1 teaspoon cinnamon
Sprinkle with topping. Bake at 400 degrees for 20-25 minutes.
I think next time I would recommend using brown sugar in the topping and then layering half the batter, half the topping, rest of batter, and remaining topping.
