Preheat your oven to 375°F (190°C) and grease a muffin tin with melted butter.
In a bowl, whisk together flour, sugar, baking powder, and salt until combined.
In another bowl, whisk milk and eggs until frothy.
Gradually combine wet and dry ingredients, stirring gently to avoid overmixing.
Fill each muffin cup two-thirds full with batter.
Bake for 25-30 minutes until golden brown and puffed up.
Allow to cool slightly before dusting with powdered sugar and serving warm.
