Add flour, sugar, baking powder and salt to a bowl. Whisk gently until fully combined without any lumps remaining.

In another bowl, mix oat milk, egg, melted butter and vanilla. Stir well so everything blends into a smooth liquid.

Pour wet mixture into the dry bowl slowly. Stir gently just until combined. Do not overmix to keep pancakes fluffy.

Place a nonstick pan on medium heat. Lightly grease the surface with butter or oil for easy flipping and even browning.

Pour batter onto the pan in small circles. Cook until bubbles appear and edges look set before flipping carefully.

Turn pancakes gently with a spatula. Cook another minute or two until golden and fluffy on both sides, then remove.

Continue cooking remaining batter in batches. Stack pancakes on a warm plate to keep soft and tender before serving.

Top pancakes with syrup, fruit or butter. Enjoy the fluffy texture and sweet oat milk flavor with your loved ones.
