# Steps:
01 - Preheat oven to 350°F. Line a 12-cup muffin tin with cupcake liners.
02 - Whisk flour, baking powder, baking soda, and salt together in a medium bowl. Set aside.
03 - In a large bowl, mix softened butter and granulated sugar using an electric mixer on medium speed until light and fluffy, about 2 to 3 minutes.
04 - Add eggs one at a time, mixing well after each addition. Blend in pure vanilla extract until incorporated.
05 - Add dry ingredients in two batches, alternating with whole milk. Mix just until combined, avoiding over-mixing.
06 - Distribute the batter evenly among cupcake liners, filling each approximately two-thirds full.
07 - Bake for 18 to 20 minutes, or until a toothpick inserted in the center emerges clean. Cool cupcakes completely on a wire rack.
08 - Beat softened butter in a bowl on medium speed until creamy. Gradually add powdered sugar, mixing on low until combined.
09 - Pour in whole milk and vanilla extract, then beat on high for 2 to 3 minutes until light and fluffy.
10 - Divide buttercream evenly among 4 to 5 bowls. Tint each portion with a different pastel gel food coloring and blend thoroughly.
11 - Fit a piping bag with a large star tip. Arrange colored buttercream side by side in the bag for a swirled effect.
12 - Pipe buttercream onto cooled cupcakes in a generous swirl. Finish with butterfly decorations and sprinkles as desired.
