Yeasted chocolate coffee cake

I saw this recipe on Martha Stewart TV yesterday.
the way the cake/bread looked SO good on the show I couldn't wait to make it
I downloaded the recipe last night and I was happy to find out that I had all the ingredients.










This is like a brioche dough but marbled with chocolate and has crumb topping.
Crumbs fell to the sides and made marble cookies, yum!




It has tons of butter so it's really rich and moist.



while it's been baking in the oven, your whole house smelled like heaven!
