I don't usually like cinnamon in chocolate either - being a purist, I prefer my chocolate without
spices - I just like a touch of vanilla extract and sometimes some espresso to boost the chocolate flavor. But in this case, I love the cinnamon in the filling. I've even tried the filling without the cinnamon, and it really fell flat, so I always use it. But...I use a mild cinnamon, ie, Korintje - I wouldn't like it with a spicy, stronger cinnamon.
I'm not sure if you're redeemed yet - maybe you need to go eat some chocolate first, then call me in the morning!
