In a large mixing bowl, combine cornmeal, all-purpose flour, baking powder, and salt. Stir until well mixed.

Make a well in the center, add the egg or flaxseed mixture, and gradually add water, stirring until a thick batter forms.

Heat oil in a cast-iron skillet over medium heat until shimmering. Test readiness with a small spoonful of batter.

Spoon batter into the skillet, flatten slightly, and fry for 3-4 minutes on each side until golden brown.

Transfer cooked hoecakes to a paper towel-lined plate to drain excess oil, serve hot with toppings.
