# Directions:
01 - Preheat oven to 350°F. Line a 12-cup muffin tin with liners.
02 - Whisk together flour, baking powder, baking soda, and salt in a medium bowl; set aside.
03 - In a large mixing bowl, beat softened butter and granulated sugar with an electric mixer until pale and fluffy, 2 to 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract until incorporated.
05 - On low speed, add dry ingredients in two additions, alternating with milk. Mix just until batter is smooth; do not overbeat.
06 - Divide batter evenly among liners, filling each about two-thirds full. Bake 18–20 minutes, until a toothpick inserted into the center emerges clean. Cool cupcakes completely on a wire rack.
07 - In a clean bowl, beat softened butter on medium speed until smooth. Gradually incorporate powdered sugar with the mixer on low speed.
08 - Blend in milk and vanilla extract. Beat on high speed for 2–3 minutes until light and aerated.
09 - Divide buttercream among 4 to 5 bowls. Tint each portion with pastel gel food coloring, ensuring colors are evenly blended.
10 - Spoon colored buttercream side by side into a piping bag fitted with a large star tip to create a multi-color swirl effect.
11 - Pipe generous swirls of pastel buttercream onto cooled cupcakes.
12 - Finish with edible butterfly decorations. Add sprinkles if desired.
