Whisk together flour, sugar, baking powder, baking soda, and salt in a bowl.

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

Combine wet and dry ingredients and stir gently until just mixed.

Heat a lightly greased nonstick skillet over medium-low heat.

Drop small rounds of batter onto the skillet using a teaspoon or squeeze bottle.

Cook until bubbles form, flip, and cook until golden brown.

Serve warm with your favorite toppings.
