Preheat your oven to 350°F (175°C) and line a cupcake tray with paper liners.

In a large mixing bowl, beat the sugar and butter together until the mixture is light and fluffy.

Add the eggs to the bowl one at a time, making sure to mix well after each addition.

Stir in the vanilla extract and milk until fully combined.

In a separate bowl, whisk together the flour, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to over-mix!

Pour the batter into the lined cupcake tray, filling each liner about two-thirds full.

Bake in the preheated oven for 15-20 minutes, or until a toothpick inserted in the center comes out clean.

Once baked, allow the cupcakes to cool in the tray for a few minutes before carefully transferring them to a wire rack to cool completely.
