Preheat your oven to 350°F (175°C) and line the muffin tin with cupcake liners.
In a mixing 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. Then mix in the vanilla extract.
In another bowl, sift the flour, baking powder, and salt together.
Gradually add the dry ingredients to the wet mixture, alternating with the milk, beginning and ending with the flour. Mix until just combined.
Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
Bake in the preheated oven for 15-20 minutes or until a toothpick inserted in the center comes out clean. Allow cooling for 10 minutes in the tin before transferring to a wire rack to cool completely.
Once cooled, use a piping bag to apply a generous amount of vanilla frosting on top of each cupcake.
For the bunny ears, cut mini marshmallows in half diagonally and place them on top of the frosting.
Add two chocolate chips as the bunny’s eyes and use a small amount of pink icing to create the nose.
If desired, sprinkle green coconut flakes around the base of the cupcakes to resemble grass.
