I need a tried and true coffee cake recipe. What I am imagining is a cinnamon swirl coffee cake with the yummy streusel topping. But it cannot contain sour cream or an absurd amount of butter (I am beginning to think this is a tall order). I’ve searched the web and blogosphere and haven’t found what I am looking for yet.

Can anyone help me out? The baby needs coffee cake (it’s all I’ve been able to think about for two days).
