Mermaid Cake Recipe

How to make Mermaid Cake

A mermaid cake is a whimsical and enchanting cake that captures the essence of mythical underwater creatures. It is often adorned with vibrant colors, shimmering details, and mermaid-themed decorations.


  • 2 ½ cups all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 ¼ cups milk
  • Food coloring (blue, purple, and green)
  • Buttercream frosting
  • Edible mermaid decorations (optional)


  1. Preheat your oven to 350°F (175°C) and prepare three 8-inch round cake pans by greasing and lining them with parchment paper.
  2. In a mixing bowl, whisk together the flour, baking powder, and salt. Set aside.
  3. In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy.
  4. Beat in the eggs, one at a time, followed by the vanilla extract.
  5. Gradually add the dry ingredients to the wet mixture, alternating with the milk. Begin and end with the dry ingredients.
  6. Divide the batter evenly into three bowls. Add a few drops of food coloring to each bowl, creating different shades of blue, purple, and green for the layers.
  7. Pour each colored batter into a separate prepared cake pan. Smooth the tops with a spatula.
  8. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center of each cake comes out clean.
  9. Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely.
  10. Once the cakes have cooled, level the tops if necessary. Place one cake layer on a serving plate and spread a layer of buttercream frosting on top. Repeat with the remaining layers.
  11. Use the remaining buttercream frosting to frost the sides and top of the cake, creating a smooth surface.
  12. Decorate the cake with mermaid-themed decorations such as mermaid cake toppers, edible pearls, or seashell candies.
  13. Serve and enjoy!
