Step-by-Step Instructions

Step 1: Prepare the Cake Batter

Preheat the oven to 350°F (175°C) and grease three 6-inch cake pans.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a separate large bowl, beat the butter and sugar until light and fluffy (about 3 minutes).
Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Alternate adding the dry ingredients and milk, beginning and ending with the dry mixture. Mix until fully combined.

Step 2: Bake the Cake Layers

Divide the batter evenly among the three cake pans.
Bake for 25-28 minutes or until a toothpick inserted in the center comes out clean.
Let cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 3: Make the Buttercream

Beat the butter until creamy, then gradually add the powdered sugar, mixing well.
Add vanilla extract and heavy cream, then beat until the buttercream is smooth and fluffy.
Divide the buttercream into three bowls and tint each with pastel blue, pink, and lavender food coloring.

Step 4: Assemble and Frost the Cake

Place the first cake layer on a cake stand and spread a thin layer of pink buttercream.
Repeat with the second and third layers, using blue and lavender buttercream.
Apply a crumb coat (a thin buttercream layer) and chill for 30 minutes.

Step 5: Create the Ombré Effect

Using an offset spatula, apply blue buttercream to the bottom third of the cake, pink to the middle, and lavender to the top.
Smooth the frosting with a bench scraper, blending the colors slightly for a gradient effect.

Step 6: Decorate

Place the mermaid tail topper at the top of the cake.
Add seashell decorations and sprinkle with edible pearls.
Lightly dust with shimmer dust for an enchanting ocean-like glow.

Best Practices

Use gel food coloring for vibrant hues without altering the buttercream’s texture.
