In a medium mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, and a pinch of salt.

In another bowl, combine milk, egg, melted butter, and vanilla extract, whisking until smooth.

Pour the wet mixture into the bowl with the dry ingredients and gently fold together until just combined, leaving some lumps.

Preheat a nonstick skillet or griddle over medium heat and lightly grease it. Pour 1/4 cup of batter per pancake.

Cook until bubbles form on the surface and edges are set, about 2-3 minutes, then flip and cook for an additional 1-2 minutes.

Stack pancakes on a warm plate, serve immediately with butter and maple syrup, and enjoy!
