Mermaid Cupcakes

I have to tell you that these mermaid cupcakes were a huge hit at Willow’s birthday party. The kids could not get enough of them, and about lost their minds overt the sprinkles hiding in the middle.

And, keeping it real. The adults loved them too! Some of the adults thought that the cupcakes were from a bakery. Blushes in the corner.

Well, if people are thinking that these cupcakes are professionally made, then I just have to share the recipe with YOU! Because, y’all they are SO easy to make! I mean like crazy easy to make.

Mermaid Cupcake Ingredients

One of the great things about this mermaid cupcake recipe is that you can use box cake mix. This is a mega time saver, and allows for less clean up too. But, you will be adding a ‘secret’ ingredient to the box mix that will set these cupcakes apart from the rest!

That ingredient is vanilla bean paste. I could go on and on about my love for vanilla bean paste. It is a one two punch of vanilla that truly adds that homemade taste to your cupcake. You can literally see the vanilla bean flecks in it. So, you know this stuff is legit.

The vanilla buttercream used for the cupcakes is another incredibly easy recipe too. Because we like to keep things flexible, you can use a stand mixer or hand mixer to make the frosting as well.

These cupcakes are topped with this super easy Mermaid Bark. Y’all we are talking make this in minutes kind of easiness. And, it turns out gorgeous. This is what sets the mermaid cupcakes apart from the rest!

Mermaid Cupcake Supplies

You will need a couple of supplies to make the mermaid cupcakes.

In order to have the 3 colors of frosting blended through the cupcakes I used the Wilton 3 Color Piping Bag Coupler. This thing is seriously amazing because it comes with two tips, and 6 piping bags! If you feel like you need more piping bags, because it never hurts to have extra. You can grab more piping bags HERE.

I also used this food coloring for the green, teal, and purple frosting. And, I love these cupcake liners for the cupcakes too! They are so vibrant, and the perfect compliment to these beautiful cupcakes.

How To Make Mermaid Frosting

This frosting recipe is ridiculously easy to make! In my opinion, if you can make frosting…then make frosting. Now, I am all about some shortcuts. However, I strongly feel that homemade frosting is one of the best things ever.

With that said, it needs to be easy! You simply do not have time for a bajillion steps or ingredients.

That is what makes this vanilla buttercream so amazing. It has very few ingredients, and can be made in under 5 minutes. And, it tastes like vanilla ice cream! It is creamy vanilla heaven in your mouth!

Once you make the frosting you will simply divide it into 3 separate bowls. Add food coloring to each bowl, and you are good to go!

How To Make Mermaid Cupcakes

Let’s get to decorating the mermaid cupcakes! This process is so easy, and it looks like a million bucks!

mermaid cupcakes with center cut out

First, you will take your round decorating tip or star tip, and gently press down in the center of the cupcake. Do not push all the way through the cupcake. This creates the hiding spot for the surprise candyfetti sprinkles.

Remove the center of the cupcake as gently as possible, and place to the side for later. Add the candyfetti sprinkles to the middle of the cupcake.

Place the cupcake filling that you previously removed on top of the center. If it did not hold completely together it is not that big of a deal. You basically just want to add some cake on top for when it comes time to add the frosting.

Now, you will simply take your assembled Wilton 3 Color Piping Bag Coupler with the included star tip. Start adding frosting in the center of the cupcake, and then work your way around in a circle.

Next, you will add the Mermaid Bark. Simply press a piece into the frosting in the center of the cupcake.
