Step 1: Prepare the Cupcakes

1. Preheat your oven to 350°F (175°C). Line a cupcake pan with paper liners.
2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
3. In a large mixing bowl, beat butter and sugar until light and fluffy (about 2-3 minutes).
4. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
5. Gradually add dry ingredients, alternating with milk, starting and ending with the dry ingredients. Mix until just combined.
6. Divide the batter evenly into the cupcake liners, filling each about ¾ full.

Step 2: Bake the Cupcakes

7. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
8. Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting.

Step 3: Make the Frosting

9. In a large bowl, beat the softened butter until creamy.
10. Gradually add powdered sugar, one cup at a time, mixing on low speed.
11. Add milk and vanilla extract, then increase speed and beat until smooth and fluffy.
12. Divide the frosting into two bowls and color one portion pink, leaving the other white.

Step 4: Decorate the Cupcakes

13. Frost the cupcakes with white frosting, using a piping bag or a spatula.
14. Cut marshmallows in half diagonally. Dip the sticky side into pink sugar or sprinkles to create bunny ears.
15. Place two marshmallow ears on each cupcake.
16. Add mini chocolate chips or candy eyes for the bunny’s face.
17. Press a pink candy pearl or jelly bean in the center for the nose.
18. Sprinkle shredded coconut over the frosting for a fluffy effect (optional).
