Preheat the oven to 400 degrees. Generously spray two 12-cup muffin tins with cooking spray; set aside. (Do not use paper liners.)
In a large bowl, stir together the corn meal, jalapeño peppers, onion, sugar, salt, and cheese.
In another bowl, break three eggs and beat lightly with a whisk. Add the corn, milk, and canola oil and stir. Add this mixture all at once to the dry ingredients and stir until the dry ingredients are just moistened. Do not over mix!
Evenly divide the batter among the muffin tins.
Bake for 20 minutes or until golden brown. Cool 1-2 minutes before removing from the muffin tins.
Serve immediately or place in ziplock bags when cool and freeze to use later.
