Swirly Blue and Purple Mermaid Cupcakes

Pinterest Hidden ImagePinterest Hidden ImagePinterest Hidden ImagePinterest Hidden Image

If you’d like to add instant whimsy to any party, make some mermaid cupcakes. 

Whether you are hosting an underwater birthday party or having a fierce girls’ night in, these swirly ocean mermaid cupcakes are not as hard to make as you may think.

Let’s face it; we’re never too old for mermaids.

Important note: The Wilton mermaid tails you see pictured are not easy to deal with. The majority of them either broke while removing them from the paper or ended up breaking while handling.

Although they are super pretty, we recommend choosing another fin option.

Mermaid Cupcakes for Magical Treats

This recipe uses a box of cake mix to make these mermaid cupcakes a tad easier to create.

Since we are A Magical Mess, we like to throw in shortcuts most of the time.

We are likely to prepare baked goods at the very last minute that they are needed. Anything to shave some time off of the recipe is welcome.

If the swirled icing intimidates you, don’t let it. It’s a lot easier to create the frosting swirl when you break it down into steps.

Colors used here are Wilton teal, royal blue, and violet. The sprinkles are from Party City, and they are Tylina Sweet Shop Mermaid Sprinkle Mix.

However, if you’d rather order them, there’s a link to another option in the recipe card.

Again, we caution you against the mermaid tails we used. We will be on the hunt for a better option.

Personally, I think making mermaid tails with chocolate in a mold sounds a lot tastier than the hard sugary one.

If you want to add cookies to your underwater party, give these mini mermaid shortbread cookies a try.
