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

In a mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, and salt. Whisk together until well-blended.

In another bowl, beat the softened butter until creamy. Add the eggs one at a time and mix in the vanilla extract.

Gradually mix the dry ingredients into the wet mixture alternately with the milk, starting and ending with the flour mixture. Mix until just combined.

Spoon the batter into the prepared cupcake liners, filling each about 2/3 full.

Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean.

Once baked, allow the cupcakes to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

Once cool, frost the cupcakes with your choice of frosting and add colorful sprinkles generously.
