Mermaid Cake

Posted by

Make a splash this Memorial Day weekend with our Mermaid Cake! This adorable cake is perfect for any Memorial Day party to get ready for summer. This simple Vanilla Cake is decorated in blues, greens and purple using ColorKitchen Natural Food Dyes, that don't have any artificial colors. You can even make the Mermaids different colors if you choose, they would look awesome in hot pink and orange too! Oh, and if you're wondering where I got the adorable green pedestal, and pastel measuring spoons, they are both from World Market and I have linked the pedestal here and the measuring spoons here

  • ColorKitchen Blue Dye (find here)
  • ColorKithen Green Dye (find here)
  • ColorKitchen Pink Dye (find here)

Sand:

  • 4 organic graham crackers

Tools:

  • 6 – 6” cake pans
  • parchment paper
  • piping bags
  • decorating tips #864, 199, 21, 32, 15, 56, 4
  • cake spinner
  • cake round (optional)
  • cake spatula
  • bench scraper

Method: 

Preheat oven to 350 degrees.

In the bowl of your stand mixer fitted with paddle attachment, cream the butter, sugar and vanilla extract.

Add the eggs and mix on low until combined, scraping sides of bowl if necessary.

In a separate bowl, add the cake flour, baking powder and sea salt and whisk together.

Add the milk and cake flour mixture to the mixing bowl, and mix on low until you have a smooth cake batter.

Separate the cake batter into 3 different bowls, each should weigh about 450 g. each.

In the first bowl, add 2 tsp. Color Kitchen Foods Blue Dye. In the second bowl, add 1 tsp. Color Kitchen Foods Blue Dye. And, leave the last bowl without color. This will create an ombre cake once it is baked.

Next, line the six 6” cake pans with parchment paper.

Pour batter evenly into each cake pan about 227 g each, all colors should be poured into 2 cake pans, so you’ll have 2 cake layers of each color.

Bake for 17 minutes or until a wooden pick inserted in center comes out clean.

Once the cakes have cooled, start the frosting for the base layer. This the light blue frosting that the entire cake is frosted with. In your stand mixer fitted with paddle attachment, add the butter, powdered sugar, blue dye and water. Mix on low until all ingredients are combined, then speed mixer up to high for 1 minute or until light and fluffy.

Place the darkest cake lay on a cake spinner or stand. Place a generous amount of frosting and spread evenly. Top with the second cake layer that is the same color.

Repeat this process with the next shade of blue and then the white.

Crumb coat the cake, find a tutorial here. Then frost it so it is smooth. You don’t have to worry about getting the bottom part of the cake super smooth because you are going to cover it up with the waves anyways.

Now it’s time to make the waves frosting. In the bowl of you stand mixer fitted with paddle attachment, add the butter, powdered sugar, blue dye and water. Mix on low until all ingredients are combined, then speed mixer up to high for 1 minute or until light and fluffy.

Put in a piping bag with decorating tip #864. Pipe a wave motion, it should feel like you’re drawing a sideways “S”.

Next, it’s time to make the Mermaid frosting. In the bowl of your stand mixer fitted with paddle attachment, add the butter, powdered sugar and water. Mix on low until all ingredients are combined, then speed mixer up to high for 1 minute or until light and fluffy.

Once the Mermaid frosting is made, separate it into 3 bowls. They should weigh 113 g. each. In the first bowl, add ½ tsp. green dye and stir to combine completely. In the second bowl, add ½ tsp. blue dye and ½ tsp. pink dye and stir to combine completely. In the last bowl, add ½ tsp. blue dye and ½ tsp green dye, and stir to combine completely. You will end up with green, purple and teal.

Put the Mermaid frosting in piping bags with decorating tips. I used #56 for the teal, #4 for the purple and #15 for the green. Then I switched them out a couple times for #262 and #24. You can use any tips you like, I just found that the smaller ones that resembled star tips worked the best for filling in the scales.

Draw Mermaid fins around the cake. I got 4 Mermaid fins total, but you can do more or less. I piped scales on all the fins and then just filled in randomly with colors. This is your opportunity to have fun and do freestyle!

Once the Mermaid fins are complete, switch out the tips for #199, #21 and #32 and pipe dollops on the top all the way around the cake for the boarder.

If you want to add sand to the top, add the graham crackers to a food processor and grind until you have a sand like texture. Sprinkle the sand all on the top of the cake.

Eat cake!

Baker’s Note: To make this cake gluten free, just substitute the all natural cake flour for an organic gluten free flour mix. Also, make sure to either omit the sand or use gluten free graham crackers.
