Recipe: Coffeecake Muffins

I'm always trying to make coffeecake muffins, and they are usually o.k. Today I tried a new recipe I found here. They were so good. I'm keeping this one in my folder. The only alteration I made was that I used vanilla yogurt instead of sour cream - only because I didn't have any. Oh, and I omitted the pecans. DH isn't a fan. They are a great breakfast or brunch treat.
