In a mixing bowl, combine the ground oat flakes with water and stir until you form a thick batter.
Add the salt to the mixture, adjusting the amount based on your taste preferences. If using, stir in the baking powder for a slightly fluffier texture.
Melt the butter and mix it into the batter, followed by the eggs. Stir everything until well combined.
Heat a non-stick skillet over medium heat and lightly grease it with butter or oil.
Take spoonfuls of the batter and shape them into small oval or disc shapes.
Fry the oat shapes for 2-3 minutes per side or until they turn golden and crispy.
Remove from the skillet and place on a paper towel-lined plate to absorb any excess oil.
Serve warm, with a dipping sauce or as a side dish.
