Stir the flour, cornmeal, baking powder and skimmed milk powder together in a large bowl and add the water.
Beat well, for about 15 minutes, until the batter is very smooth and of a thick, pancake mixture-like consistency. Stir in the salt and the sugar.
Heat a non-stick frying pan over a medium high heat and spoon out two heaped tablespoons worth of batter onto the pan. Cook until browned on both sides, like pancakes.
Set aside to cool. Serve with butter.
Notes
You can omit the skimmed milk powder and replace the water with milk with successful results too.
