This recipe requires two mini muffin pans. I tested them with one regular and one silicone, and found the regular one to produce a much better muffin.   The weight of the muffin batter caused it to sink in the middle, creating lopsided muffins. It probably would have been better if I’d placed it on a baking tray, but this will also affect the way the air moves around the muffins.   I recommend sticking with regular mini muffin pans to bake this recipe.
