Marble Coffee Cake with Crumb Topping

I decided to take advantage of the fact that I was going home this weekend and use my parents' nice, huge kitchen. I haven't been able to make much more than pasta or grilled cheese sandwiches lately, so I was really excited to actually be able to bake.

My baked goods are very much in demand by family and friends. The favorite recipe seems to be my oatmeal cookies, but I'm really, really tired of baking oatmeal cookies, so I decided to go with the second most-requested: my marble coffee cake.

The cake has sour cream in it, which makes it really moist. It also has a cocoa-sugar layer in the middle, as well as a butter-flour-sugar-chocolate chip crumb topping. I love this recipe.

I had to make two cakes- one for my aunt and grandparents, and one for the guy I'm dating. Otherwise, someone would have ended up feeling left out!

Here's a picture of the cake in the pan:

Anyone drooling yet?
