So, you decided to make a mermaid cake. Good for you! There are a LOT of things you can do for a Mermaid party but having a decorated mermaid cake… takes the cake (?) Ok, that was a bad play on words but really, it adds to the atmosphere and gives a stunning centerpiece.  Let’s get started!


Cake Supplies

So mer-peeps, if you are like me (not so domestic) you will need some help from the very beginning.  Can we start from ground zero? If you are experienced making and stacking cakes, skip to down to decorating section.

Let’s talk cake supplies.

You will need some cake pans, parchment paper, a cake turntable, icing spatula, and some frosting supplies.

The classic mermaid cake is usually one solid tier cake with a topper and decorations. The possibilities are endless when it comes to making/decorating a cake so I will provide you with the basics and you can take it from there.


Bake the cake

The actual making and baking of the cake aren’t too hard. It’s the whole “stacking” thing that gets me.  I am NOT going to pretend to be an expert on this so I will let a professional tell you how.

Thanks, Bridget! You make it look so easy!


Mermaid cake Frosting

The best frosting to shape and decorate your cake is called Buttercream Frosting. It’s easy to spread and holds its shape well. Here is a simple recipe video that will help. This is where you can add any color to your frosting.


Time to Decorate!

This is where I come in! There is a WHOLE range of things you can do with these cakes. Hopefully, some of these ideas can help!

Decorating with Frosting

If you have confidence in your cake decorating abilities, try something more extravagant with the icing tips. There are other things you can do with the mermaid cake besides putting decorations on top. Check out these videos on how to make waves!


Fondant for mermaid cakes

Fondant is a different kind of icing that is much denser allowing more creative decorations out of actual frosting. If you are willing to venture then I give you mad props. These kinds of cakes are next level.

It can get expensive if you buy at the store but below is a video of how you can make fondant at home for under $3! Doesn’t seem to hard, does it?

You can totally cover your whole cake in fondant icing, or just make fun under the sea edible decorations with some mermaid soap molds using fondant.

I really like this last video with the fondant as waves. Maybe I will do this when I have a few fondant cakes on my resume.


Good luck with your mermaid cake! Let me know how it turns out!
