Building on the mermaid cake trend, I wanted to make some mermaid cupcakes!
They’re the first cupcake of a cupcakes series I’m starting on YouTube, and I wanted to kick things off with something colorful!
To make these mermaid tail cupcakes, I used my favorite vanilla cupcake recipe. It’s a slightly modified version of Life Love and Sugar’s Vanilla Cupcake Recipe.
I swapped out the regular milk and used buttermilk (my personal preference!), because I simply love the moisture and tang that buttermilk adds to baked goods.
Another alteration that makes them incredibly easy to make??
The batter for there mermaid cupcakes comes together in one bowl! I hate making extra dishes, and always try to simplify recipes if possible.
To ensure your mermaid cupcakes turn out moist and tender, be sure that you don’t overmix the batter!
Mix it just until the ingredients are incorporated.
It’s also important to make sure that your ingredients are all at room temperature, so that your batter will bake and rise evenly.
I like to frost my cupcakes with a half batch of my American buttercream, and usually use a Wilton 1m tip (open star).
Vanilla Mermaid Cupcake Batter:
- 1 1/4 cup all purpose flour (150g)

Yield: 12-14 cupcakes
Prep time: 10 minutes
Bake time: 18 minutes
Start with the Mermaid Cupcakes
Preheat oven to 350°F (175°C) and place cupcake liners in baking pans.
Add the flour, sugar, baking powder and salt to a large mixer bowl and gently mix.
Pour in the buttermilk, and gently stir until just combined.
Next, add in the water, vanilla, and vegetable oil, and mix until the batter comes together.
Mix in the egg until well combined.
Divide the batter evenly between 3 bowls, and color one a light purple, one a light blue, and one green.
Alternate spooning the different colored batters into the cupcake liners, to create a layered look.
Fill the cupcake liners about 1/2 way full, and bake for 18-20 minutes, or until a toothpick comes out clean.
Allow the cupcakes to cool for 5 minutes before moving them to a cooling rack to finish cooling.
Create the Mermaid Tails
While the mermaid cupcakes bake and cool, make the mermaid tails.
Color 1/2 cup white fondant light purple, 1/2 cup light blue, and 1/2 cup light green using gel food coloring.
Knead the color into the fondant, twisting and pulling until the color is evenly spread throughout the fondant.
Add 1/2 tsp of tylose powder to each color, to accelerate the firming process.
If the fondant gets sticky, let is rest for a few minutes, then resume kneading.
Combine the three colors into one long log, and twist the colors together.
Roll this out, the fold one more time repeat to blend the colors together.
Cut out a 2 inch mermaid tail from cardboard, and use this a template to cut out 12 mermaid tails.
Use the wide end of a round frosting tip to make a webbed pattern at the end of the tail.
Flip the frosting tip over, and use the smaller opening to make the scales on the tail.
Use a fondant tool of knife to score the tail.
Place on parchment paper and set aside for at least 2 hours to harden.
Make the Vanilla Buttercream Frosting
Next, prepare the vanilla frosting.
Beat the butter on medium speed for 30 seconds with a paddle attachment, until smooth.
Slowly add in the powdered sugar, 1 cup at a time.
Add the heavy cream half way through.
Once fully mixed, add in the vanilla and salt, and beat on medium low until the ingredients are fully incorporated, and the desired consistency is reached.
If the frosting is too thick, add in cream (1 Tbsp at a time). Or if the frosting is too thin, add in more powdered sugar (quarter of a cup at a time).
Divide the frosting between 2 bowls, and color one light purple, and the other light blue using a drip of gel food coloring.
Place the light purple into a frosting bag with a round opening (I cut my piping bag to have a 2 cm opening).
Put the light blue frosting a separate bag with an open star tip (Wilton 1M).
Decorate These Mermaid Tail Cupcakes
Once the cupcakes are fully cooled, add a swirl of purple buttercream.
Pour mermaid sprinkles into a small bowl, and dunk the cupcake into the sprinkles to cover the frosting entirely.
Pipe a swirl on top of each cupcake, and then gently insert the fondant mermaid tail into the center of the swirl.
