this recipe

1. Bake the Cupcakes:
   • Preheat your oven to 350°F (175°C) and line a cupcake pan with cupcake liners.
   • Prepare cake batter according to the instructions on the box.
   • Optional: Divide the batter into three bowls and tint each with gel food coloring. Swirl or layer the colored batters into each liner for a marbled effect.
   • Fill liners about 2/3 full and bake for 18–20 minutes or until a toothpick inserted in the center comes out clean.
   • Let cupcakes cool completely on a wire rack.
2. Make the Frosting:
   • In a large mixing bowl, beat the softened butter until fluffy.
   • Gradually add powdered sugar, one cup at a time, mixing well.
   • Add vanilla extract and enough cream or milk to achieve a smooth, pipeable consistency.
   • Divide the frosting into three bowls and tint each with teal, purple, and pink food coloring.
   • Lay out a piece of plastic wrap and spoon each colored frosting in rows next to each other. Roll into a log and insert into a piping bag fitted with a star or swirl tip.
3. Decorate the Cupcakes:
   • Pipe the tri-colored frosting onto each cooled cupcake in a swirl pattern.
   • Top each cupcake with a mermaid tail topper.
   • Add edible pearls, shimmer sprinkles, and glitter as desired to complete the undersea look.

FAQs

Can I use homemade cake batter instead of a mix?

Yes, a homemade white or vanilla cupcake recipe works perfectly. Just be sure it’s sturdy enough for decorating.

Where can I get mermaid tail toppers?

You can make them using silicone molds and candy melts or buy pre-made ones online or at craft stores.

How do I make multicolor frosting?

Tint frosting in three colors, line them side-by-side on plastic wrap, roll into a log, and insert into a piping bag for a swirled effect.

What’s the best food coloring to use?

Gel food coloring is best because it delivers vibrant colors without thinning the frosting.

Can I make these cupcakes ahead of time?

Yes, bake and freeze the cupcakes in advance. Decorate the day you plan to serve for the freshest look.

Are these cupcakes suitable for kids’ parties?

Absolutely! Kids love the bright colors and fun decorations. They’re also a great baking activity for older children.

Can I use whipped cream instead of buttercream?

You can, but whipped cream may not hold up well for detailed piping or warm weather.

Do I need to refrigerate these cupcakes?

Only if using perishable decorations or if stored longer than 2 days. Otherwise, they’re fine at room temp in a sealed container.

What if I don’t have a piping bag?

Use a zip-top bag with a corner snipped off. It won’t be as fancy, but it works!

How can I add shimmer?

Use edible glitter or shimmer spray for a magical touch. A little goes a long way!
