Preheat your oven to 350°F (175°C) and line a cupcake tin with liners.
In a bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract and mix until combined.
In another bowl, whisk together the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
Mix until just combined, being careful not to overmix.
Add the pink food coloring until the desired shade is achieved.
Divide the batter evenly among the cupcake liners.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Let the cupcakes cool completely before frosting.
