Preheat oven to 400 degrees and prep muffin tin with either cooking spray or liners.
Mix dry ingredients together. If you'd like more rosemary flavor, mix rosemary and sugar and rub together with your fingers. Set aside.
Whisk wet ingredients together (leave corn out) and pour into dry ingredients. Whisk or stir together with a spatula. Don't over-stir and don't worry about lumps! Once everything is combined fold in the corn.
Fill muffin tin and bake for 15-18 minutes or until the tops are golden brown. Let cool on a wire rack and enjoy with a nice bowl of chili!
