In a large mixing bowl, whisk together the flour, baking powder, salt, and sugar until well combined.

In a separate bowl, crack the egg, then pour in the milk, melted butter, and vanilla extract. Whisk until blended.

Make a well in the dry ingredients and pour in the wet mixture. Fold gently until just combined.

Preheat a skillet over medium-low heat for 2 minutes and add butter to coat.

Pour approximately 1/3 cup of batter into the skillet and cook for 2-3 minutes until bubbles form.

Flip the pancakes and cook for an additional 1-2 minutes until golden brown.

Stack the pancakes on a warm plate, top with accompaniments, and serve.
