Mermaid Cake

Mermaid Cake is a layered vanilla cake flavored with yogurt, milk, and buttercream frosting incorporating melted white chocolate. The cake batter uses all-purpose flour, sugar, baking agents, and egg whites to create moist, tender layers. The frosting blends salted butter, powdered sugar, vanilla, melted white chocolate, and cream, with optional blue and green food coloring to create a decorative ombré or mermaid-inspired effect. This celebration cake combines soft crumb layers with rich, sweet frosting suitable for special occasions.

Description

The cake layers are made by sifting together dry ingredients including flour, baking soda, and powder, then mixing wet ingredients—yogurt, milk, sugar, butter, egg whites, and vanilla—before folding them together just until combined. The batter is portioned into three six-inch pans and baked until the centers spring back to a light touch, yielding soft, moist layers.

The buttercream frosting is prepared by melting white chocolate into cream, then whipping salted butter with powdered sugar and vanilla before incorporating the cooled chocolate mixture. The frosting achieves a smooth, creamy texture suitable for piping. Colored portions of frosting can be prepared with blue and green hues to pipe scale-like rings between cake layers and for decorative outer frosting to achieve a mermaid theme.

Assembled cake layers are stacked with alternating colored buttercream rings and a crumb coat of frosting applied to seal crumbs. The cake is then finished with a final thin frosting layer and decorative piping. This cake can be scaled up using larger pans by doubling or tripling the recipe.

Measuring flour correctly and avoiding overmixing help ensure tender cake layers. Cake strips can help achieve flat, even layers by preventing doming during baking. Substituting plain Greek yogurt for sour cream in the batter is an acceptable variation.

  • 3 egg room temperature, white
  • 1 tbsp vanilla extract 15ml
  • 1/2 cup yogurt 120mL, plain, Greek
  • 1/2 cup milk 120mL, whole

For the Buttercream:

  • 3 butter room temp, 339g, salted, sticks form
  • 1.5 pounds powdered sugar 680g
  • 1 tbsp vanilla extract 15mL
  • 12 ounces white chocolate 340g
  • 1/4 cup cream 60mL
  • Food Coloring if desired

Instructions

For the buttercream

  1. Melt the white chocolate and cream together at very low heat, set aside.
  2. Beat the butter until light and fluffy, add the sugar a cup at a time and beat well. Drizzle in the white chocolate and beat until combined.
  3. Separate the buttercream into 2 equal batches and color two of the batches with blue and green food coloring in different shades of the scales.

For the Cake

  1. Butter and flour 3 six-inch cake pans. Preheat oven to 350F
  2. Sift the dry ingredients together in a large bowl.
  3. Mix the wet ingredients (including the sugar) together in a medium bowl.
  4. Add the wet to the dry and mix until just combined.
  5. Divide the mixture into 3 6″ cake pans that have been buttered and floured.
  6. Bake at 350 for about 25-30 minutes or until the centers are springy to the touch.

For the Assembly

  1. Pipe rings of the green and blue buttercream onto the first layer then cover with the second layer. Repeat step.
  2. Cover cake in a thin layer of buttercream and give a rough smooth.
  3. Place green and blue buttercream in a piping bag fitted with a large round tip. Pipe the petals by swiping up with the tip.

Notes

  • Use a kitchen scale to measure flour accurately for best texture; spoon and level if you don't have a scale.
  • Fluffy mix with little clumps of butter in wet ingredients is normal; batter evens out once dry ingredients are incorporated.
  • When changing pan size, double the recipe for 8-inch pans and triple for 9-inch pans to maintain layer thickness.
  • Use cake strips or make your own to encourage flat cake layers and even baking.
  • Plain Greek yogurt can substitute sour cream without noticeable difference in flavor or texture.
