Chocolate and caramel are always a pick-me-up in this house. My children love this coffee cake and ask for it instead of a regular cake for their birthdays or holidays. The caramel adds just the right touch to make the flavor burst with every bite.
Mix first eight ingredients and caramel chips to form dough, divide dough in 1/2 and spread first half into 9x13 buttered and floured baking pan. Cover dough with 1/2 the semi-sweet chocolate chips and sprinkle with cinnamon sugar mixture. Spread 2nd half of dough on top and repeat with 2nd half of chocolate chips and cinnamon sugar.
Bake at 350 degree for 30 minutes. This coffee cake is good warm and cold! If you want to, sometimes I add a caramel drizzle on the top and serve it warm with a dark Colombian coffee.
