In a large mixing bowl, whisk together the whole egg, egg whites, and 0.5 cup of the Greek yogurt until completely smooth.
Slowly whisk in the chickpea flour, lime zest, sea salt, black pepper, and smoked paprika until the batter is thick and free of lumps.
Fold in the corn kernels, thinly sliced scallion, and chopped cilantro until evenly distributed throughout the mixture.
Heat the avocado oil in a large non-stick skillet over medium heat until shimmering.
Drop the batter into the skillet using a 1/4 cup measure for each fritter, pressing down gently with a spatula to flatten them into patties.
Cook for 3 to 4 minutes per side until the fritters are golden-brown and the centers are set.
In a small bowl, stir together the remaining 0.25 cup of Greek yogurt with the lime juice and a tiny pinch of salt to create a zesty crema.
Serve the warm fritters immediately with a dollop of the lime-yogurt crema and a garnish of fresh cilantro.
