In a mixing bowl, whisk together the gluten-free flour, sugar, baking powder, and salt.

In another bowl, mix the milk, egg, melted butter, and vanilla extract until well combined.

Pour the wet mixture into the dry ingredients and stir gently until just combined.

Heat your non-stick skillet or griddle over medium heat.

Using a 1/4 cup measure, pour the batter onto the skillet.

Cook the pancakes for about 2-3 minutes or until bubbles form on the surface.

Carefully flip each pancake and cook for another 1-2 minutes until golden brown.

Remove the pancakes from the skillet and serve immediately.
