First I want to say that I made these EXACTLY as the recipe states... NO alterations whatsoever. They were great Chocolate Chip Cupcakes, but really wouldn't call them muffins. Also, the batter is a little too thin to add chocolate chips... they just sink to the bottom and get stuck on the pan. I'm not an expert, but I would say that generally muffins are denser and more substantial than cupcakes, and these are very light and fluffy (again, great for cupcakes, not very good for a breakfast item). I made one pan (12) and tossed the rest of the batter. Will keep looking for a REAL chocolate muffin recipe, or continue to buy mine at Costco.
