To the expert bakers of Food52:
I recently posted this recipe (http://theroamingkitchen.net/strawberry-coconut-cupcakes-with-coconut-cream-cheese-frosting/); while all my tests came out well, I've had a few comments of cupcakes with sunken/mushy middles. This won't do!
I thought it might be too much liquid in the batter. Could the evening agent have to do with the problem? Any and all advice appreciated. Thanks!
