Mix Dry Ingredients: In a large bowl, whisk together the yellow cornmeal, all-purpose flour, baking powder, kosher salt, and sugar until well combined.
Prepare Wet Ingredients: In another bowl, beat the eggs. Add milk, water, and melted butter to the eggs, and whisk together until fully combined.
Combine Ingredients: Pour the wet ingredients into the bowl with the dry ingredients. Stir until just combined, making sure not to overmix.
Heat Oil: In a large cast-iron or non-stick skillet, heat 2 tablespoons of your chosen frying fat (vegetable oil, bacon grease, etc.) over medium heat until it shimmers.
Fry Johnny Cakes: Using a 1/4 cup measuring cup, scoop the batter and pour it into the hot skillet. Cook each cake for about 4-5 minutes on one side, or until the edges turn golden brown. Flip and cook for another 4-5 minutes until the other side is golden brown as well.
Serve: Remove the Johnny Cakes from the skillet and place them on a paper towel-lined plate to drain any excess oil. Serve hot with butter and a generous drizzle of maple syrup.
Repeat: Continue frying the remaining batter in batches, adding more oil to the skillet as needed.
Enjoy your freshly made Johnny Cake recipe warm with butter and syrup!
