Preheat your oven to 350°F. In a large bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in vanilla extract. In another bowl, combine flour, baking powder, and salt. Gradually add to the wet mixture, alternating with milk, until just combined. Add red food coloring to achieve the desired pink hue.

Line a muffin tin with heart-shaped liners. Fill each liner two-thirds full with the batter. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

In a bowl, beat the butter until creamy. Gradually add powdered sugar, vanilla extract, and heavy cream, beating until smooth. Add food coloring to achieve a romantic pink or red shade.

Fill a piping bag with the frosting and use your favorite tip to decorate the cooled cupcakes. Create swirls, roses, or other romantic designs. Add sprinkles or edible glitter for extra flair.

Arrange the decorated cupcakes on a platter or a tiered stand and serve at room temperature. They are ideal for Valentine's Day celebrations or any romantic occasion.

Store leftover cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for up to a week. Bring to room temperature before serving for best taste.
