How to make a simple mermaid tail cupcake recipe. This is easy to make even if you're not a cake decorator.

I used a box cake mix to make my cupcakes, but you can use your favorite white cake recipe. However, I do recommend making the buttercream icing from scratch. It tastes better and will pipe better.

I also added a mermaid tail that i made by melting candy wafers and pouring into a mermaid tail mold. Then I topped the cupcakes with mermaid sprinkles.

These mermaid cupcakes are simple to make and would be perfect for a birthday party! You can make them a few days ahead of time or even freeze the cupcakes to frost the day before the party to save time.

For the Cupcakes
  • 1 15.25 ounce white cake mix
  • 1 1/4 cups water
  • 1/3 cup vegetable oil
  • 4 egg whites
For the Frosting
  • 2 sticks of salted butter, softened
  • 1 teaspoon vanilla extract (make your own vanilla extract from vanilla beans or make Instant Pot vanilla extract)
  • 3-4 cups powdered sugar
  • 3 tablespoons half and half
  • Green, blue, and purple gel food coloring
  • Edible pearl luster dust
  • White candy melts or white chocolate chips
  • Mermaid sprinkles
For the Cupcakes
Preheat oven to 350 degrees Fahrenheit. Line a muffin tin with paper liners or spray with cooking spray.
In a large mixing bowl, combine the cake mix, water, oil, and egg whites. Use a hand mixer to beat on medium until fully mixed.
Fill cupcake liners 2/3 full. Bake for 18 to 20 minutes. The mermaid cupcakes are done when a toothpick inserted into the center comes out clean. Remove from the oven and place on a cooling rack and let cool completely.
For the Frosting
In a large mixing bowl, cream the butter for 2 minutes or until light and fluffy. Stir in the vanilla extract.
While mixing, slowly add the powdered sugar 1 cup at a time. Alternate with 1 tablespoon of the half and half. Mix until creamy and stiff peaks form. Add the luster dust until it's as shimmery as you you want.
Divide the frosting into three containers. Add food coloring to each bowl to make purple, green, and blue. Stir well.
Add each color to its own small piping bag and then place the three smaller bags into a large piping bag. You can also use a tricolor icing bag.
Squeeze a small amount of frosting on a plate to get the three colors combined. Then frost your easy mermaid cupcakes.
Melt the white chocolate or candy wafers. Add candy melt coloring if needed and pour into a silicone mold. Let set up until hardened. Remove from the mold and place a tail on the mermaid tail cupcakes. Sprinkle with mermaid sprinkles.
