Caramel Chocolate Streusel Coffee Cake

Why I Love This Recipe
I found this recipe on the Cookie Madness blog and made it for the first time today. It's really very good! One note, I did not have any of the caramels on hand, but I did have some caramel ice cream sauce. I used that and it worked just fine! I also used a 10 inch pan, so it came out a little thinner. I hope you enjoy this cake as much as we did.
