The key is to keep your crepe batter thin and be careful not to overheat your chocolate. If you want to take it up a notch, flambe the finished product with Grand Marnier for a delightful liqueur ...
Just whip it out of the freezer 10 minutes before slicing or scooping. I like to add a little extra Grand Marnier to the mix. If you have fresh berries, great, otherwise frozen are just fine.
