In a large bowl, combine the corn kernels, flour, cornmeal, baking powder, chili powder, garlic powder, smoked paprika, salt, and pepper. Mix until everything is evenly combined.
Stir in the grated Cotija cheese, chopped cilantro, egg, and milk. Mix again until you have a thick batter.
Heat about 1 inch of vegetable oil in a skillet over medium heat. Once the oil is nice and hot (around 350°F or 175°C), carefully spoon portions of the batter into the oil. Flatten them a bit with the back of a spoon.
Fry the fritters for 2-3 minutes on each side or until they turn golden brown and crispy.
Remove them from the skillet and let them drain on a paper towel-lined plate.
Serve warm with lime wedges and an extra sprinkle of Cotija cheese. Enjoy them right away!
