Preheat your oven to 375°F (190°C) and grease a mini muffin pan.

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

In a separate bowl, combine the milk, egg, melted butter, and vanilla extract and whisk until blended.

Gently pour the wet ingredients into the dry ingredients and fold together, being careful not to overmix.

Fill each muffin cup about two-thirds full with the batter.

Bake in the preheated oven for 10-12 minutes until golden brown and a toothpick comes out clean.

Let cool for about 5 minutes before serving warm with maple syrup or fresh fruit.
