From TOH magazine. It sounds a lot like the Bisquick coffeecake I love but without using Bisquick (which I don't like to bake with). Cooking time includes 10 minutes cooling time. Note: I find the vanilla flavor to be a bit strong and makes it a bit too sweet for my taste. I don't think I'll use it in future, but I'll leave it in as optional for those who might like their coffee cake a bit more sweet than cinnamony.
