In a medium bowl, whisk together oatmeal flour, baking powder, and salt until well combined.
In a separate large bowl, whisk together mashed bananas, eggs and vanilla extract.
Whisk together until well combined.
Pour dry ingredients into the large bowl of wet ingredients.
Add 3 tablespoons of melted butter (unsalted). Whisk together until well combined.
Melt 1 tablespoon unsalted butter in a large skillet over low-medium heat.
Test skillet to see if it's hot enough by dropping small "dots" of water into the bottom. If they sizzle and move around, the skillet is HOT enough for cooking.
Pour in 1/3 cup of batter to create a pancake. Three will fit into a large skillet. Cook 3 to 4 minutes on each side. When the edges look dry, flip over and cook another 3 to 4 minutes.
Repeat until all batter has been cooked.
Serve hot.
Drizzle with maple syrup or buttery pancake syrup. Top with sliced bananas or preferred fruit.
