# Instructions:
01 - Preheat oven to 350°F. Line a 12-cup muffin tin with cupcake liners.
02 - Whisk together flour, baking powder, baking soda, and salt in a mixing bowl; set aside.
03 - Use an electric mixer to cream softened butter and granulated sugar until light and fluffy, about 2–3 minutes.
04 - Add eggs one at a time, beating after each addition. Mix in vanilla extract until combined.
05 - Add dry ingredients in two batches, alternating with milk, mixing until just combined.
06 - Divide batter evenly among cupcake liners, filling each about two-thirds full. Bake 18–20 minutes until a toothpick inserted in center comes out clean. Cool completely on wire rack.
07 - Beat softened butter on medium speed until creamy. Gradually add powdered sugar, mixing on low. Add milk and vanilla; beat on high 2–3 minutes until light and fluffy.
08 - Divide buttercream evenly into 4–5 bowls. Tint each with a different pastel gel color and mix thoroughly.
09 - Fit a piping bag with a large star tip. Spoon alternate colored buttercreams side by side for swirled effect.
10 - Pipe buttercream onto cooled cupcakes in generous swirls, then top each with butterfly decorations and sprinkles as desired.
