Preheat the oven to 350°F (175°C) and line a cupcake tin with cupcake liners.

In a bowl, whisk together the all-purpose flour and baking powder.

In a separate bowl, beat together the softened butter and sugar until light and fluffy.

Mix in the eggs, one at a time, followed by the vanilla extract. Beat until well combined.

Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the flour mixture; mix until just combined.

Divide the batter into separate bowls and add different food coloring to achieve your desired pastel shades.

Using a spoon or a scooper, fill each cupcake liner about halfway with batter.

Place the tray in the oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cupcakes to cool in the tin for about 5 minutes, then transfer them to wire racks to cool completely.

Once cooled, pipe your favorite frosting on top of each cupcake and add sprinkles for decoration.
