*I did find the muffins a little sweet, which takes away from the chocolate flavor, I would cut back the sugar to one cup. *I didn't add the espresso powder, with the cream cheese filling I wanted the chocolate to be the only other flavor, If I omitted the cheesecake filling I would have definitely used the espresso powder. *you can smooth over the chocolate muffin batter to completely enclose the cheesecake filling or leave it open at the top the way I did.
