Heat 2 inches of oil in a heavy pot or deep fryer to 350F.
Oil for frying
Spread the crab on a sheet pan and pick through it for shell. Drain the corn and pat it dry.
Whisk the Jiffy mix and Old Bay together in a large bowl.
1 box Jiffy Corn Bread Mix, 1 Tablespoon Old Bay Seasoning
Whisk the eggs and milk together, pour into the dry ingredients, and stir just until no dry pockets remain.
2 Egg, ¾ Cup Milk
Fold in the corn and green onions, then gently fold in the crab.
3 Green Onions, 2 cups corn, 8 ounces crab meat
Drop the batter by small cookie scoop into the hot oil, 5 or 6 at a time. Fry 1 to 2 minutes per side until deep golden brown and cooked through (160F in the center).
Drain on paper towels and dust with Old Bay right away. Let the oil return to 350F between batches. Serve hot.
