Preheat the oven to 350°F. In a large mixing bowl, sift together the flour, baking powder, baking soda, and salt. In a separate bowl, cream the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined and the batter is smooth.

Line a cupcake tray with liners. Fill each liner two-thirds full with batter. Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean. Let cool completely on a wire rack before frosting.

In a large mixing bowl, beat the cream cheese and butter until smooth. Gradually add the powdered sugar and beat until creamy. Stir in the vanilla extract and green food coloring until the desired shade is achieved.

Use a piping bag fitted with a star tip to pipe the frosting onto the cooled cupcakes in a swirl, creating a tree shape. Decorate with sprinkles and candy stars as desired.

Arrange the cupcakes on a festive tray or dessert table. Serve with your favorite holiday beverages for a complete festive experience.

Store any leftover cupcakes in an airtight container in the refrigerator for up to 3 days. Allow them to reach room temperature before serving.
