Mix the oatmeal, flour, and salt with the water to form a thin batter. Add the baking powder just before cooking.
Grease a large frying pan and heat on high. Pour cupfuls of the batter into the hot pan and cook like thick pancakes for 4 to 5 minutes on each side until golden brown.
Serve hot with bacon and eggs or sprinkled with lemon juice and sugar.
You can also serve them later, warmed up or toasted with cheese.
