Prepare the Batter: In a medium-sized mixing bowl, combine the gluten-free flour and baking powder. Add the beaten egg and almond milk, and mix until the batter is smooth and free of lumps.
Add the Vegetables and Seasonings: Stir in the corn kernels, chopped green onions, salt, black pepper, paprika, and cayenne pepper until evenly distributed throughout the batter.
Heat the Oil: Heat a generous amount of avocado oil in a cast iron skillet over medium heat. The oil should be hot enough that a drop of batter sizzles upon contact.
Cook the Fritters: Using a 1/4 cup measuring cup, drop spoonfuls of the corn mixture into the hot oil. Cook for about 3 minutes on one side, then flip the fritters and press them down gently to flatten. Continue cooking for another 5 minutes, flipping as needed, until the fritters are golden brown and crispy on both sides.
Serve: Remove the fritters from the skillet and drain them on a paper towel-lined plate. Garnish with additional chopped green onions if desired. Serve warm with your favorite dipping sauce.
