In a large bowl, combine all the dry ingredients. Create a well in the center, then add the milk, melted butter, vanilla extract, and egg.
Whisk everything together until the batter is smooth. A few small lumps are fine. The batter should be thick—add a little extra milk if you prefer a thinner consistency.
Heat a nonstick pan or griddle over medium-low heat and lightly grease it with butter.
Pour about ¼ cup of batter onto the pan and gently spread it into a round shape using the back of the measuring cup.
Cook until the bottom turns golden and bubbles begin to form on the surface. Flip using a spatula and cook the other side until golden.
Repeat with the remaining batter. Serve warm with maple syrup, honey, or fresh fruit.
