I love this because I can mix it up the night before and the next morning all I have to do is pop it in the oven for fresh, hot coffeecake.
Sometimes I add coconut to the topping. When my kids were little, I poured the batter into 2 round cake pans instead of the 9"x13" pan. I baked baked both coffeecakes the next morning, one to eat and one to freeze. The coffeecake fit nicely into a gallon-size Ziploc bag.
