Cinnamon Roll Cake

Wow, I was on a roll in January. 10 posts in a month. See if I can keep up the pace for February.
Let's start with this cake...... YUM! It's like walking through the Mall and getting closer and closer to the Cinnabon kiosk then you realize you're in your own home. Not only does it smell delightful but it tastes delightful also. You think you're eating a cinnamon roll then you realize that it actually has the texture of a cake. I'll be making this one again for sure.
