If using corn on the cob, cut all the kernels off the cob. If using canned or frozen corn, make sure the corn is thawed and dry. Add the corn to a large bowl. Add in the diced green cilantro, green onion, diced jalapeno, and squeeze in the lime juice.
In a small bowl add the flour, baking powder, salt, black pepper, chili powder and stir to combine. Pour the dry ingredients into the bowl with the corn. Stir to mix together. Pour in the beaten eggs, milk, and cheese. Stir to combine. Will be a thick batter.
Place a scoop of the corn fritter batter, into hot oil. Use a rubber spatula to create a patty shape. Let the batter cook in the oil for about 2-3 minutes, you will see the edges starting to turn golden. Then carefully flip to cook the other side. Once both sides are golden brown, place on a paper towel lined tray to absorb extra oil.
