Gather all ingredients for smooth preparation.

In a large bowl, mix sweet corn, flour, baking powder, eggs, green onions, chili powder, and lime juice until just combined.

Heat oil in a skillet over medium heat. Test by dropping in a small spoonful of batter.

Spoon about two tablespoons of batter per fritter into the skillet and flatten slightly. Cook for about three minutes per side until golden brown.

For the aioli, combine mayonnaise, chili sauce, lime zest, and juice in a bowl until smooth.

Serve fritters hot with the chili lime aioli on the side for dipping.
