In a bowl, whisk together the all-purpose flour, baking powder, salt, garlic powder, onion powder, and sugar until evenly combined.
In another bowl, beat the egg, low-fat milk, and melted butter until smooth.
Mix the wet ingredients into the dry, and then gently fold in the drained corn. Use a spoon to drop small mounds of the batter into the hot oil. Cook for about 2-3 minutes, until golden brown.
