Halloween Unicorn Cupcakes

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

Combining mystical unicorns with Halloween is meant to be – what is a more magical creature than a unicorn? And Halloween is all about the magic and the mystery!

I mean, I know they’re not typically associated with this time of the year, but these green Halloween unicorn cupcakes are too pretty not to make for the spooky season!

They start as a box of cake mix which is colored purple (obviously!) and orange – two of the most Halloween-y colors on the planet – and then topped with green frosting, sprinkles, more frosting, and unicorn cupcake decorations.

You will not be disappointed with these amazing cupcakes, and if you’re serving them at a seasonal soiree, your guests will not be disappointed either!

Ingredients & Equipment Used In This Recipe

You may have some baking ingredients in your kitchen already – the full list with measurements is found in the recipe card.

For your convenience, any specialized or notable ingredients and equipment needed to make these cupcakes have been listed below and linked to Amazon if available online.

This recipe uses American cups. They’re a handy piece of kitchen equipment to have along with a kitchen food scale. Having both in your kitchen means you’ll be able to make all of the different recipes on my blog as I use both cups and weighted measures.

Halloween Unicorn Cupcakes Recipe Tips

Cupcake Making Tips

  • French Vanilla cake mix is essentially vanilla cupcakes with the vanilla flavored amped up. You can use just a regular vanilla cake mix if you can’t source the French Vanilla. I mean, you could make your own cupcakes from scratch if you like and not use a cake mix at all!
  • Use festive Halloween-themed cupcake liners to bake your cakes in.
  • The cupcake batter is divided into two and colored with food coloring – one orange, and one purple.
  • Food coloring is available in various forms. You’re most likely to find liquid coloring in your grocery store, and other types of coloring like gels, pastes, and powders in more specialised cake decorating shops. The cheapest option is liquids, but they can alter the consistency of your frosting and cake batter, so I prefer to use pastes or gels which doesn’t. A little goes a long way with food coloring gels and you can usually get a much deeper shade than you would with liquids.
  • Remember you can always add more food coloring if you need to, but not take it away! So add a little at a time to achieve the color you want.
  • Add alternating spoonfuls of each colored cupcake batter to the liners to get a marbled effect. Fill them about two-thirds full (or until you run out of the batter).
  • The cupcakes should be ready in about 20 minutes – test their doneness by inserting a toothpick into the cakes. It should come out clean when the cupcakes are cooked through. Bake for an extra 2 minutes and check again.
  • Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely before frosting.

Cupcake Frosting Tips

  • When making the frosting you want the end result to be creamy, smooth, and for it to hold a stiff peak. You may have to adjust the amount of powdered sugar and cream slightly to achieve the consistency you need.
  • The frosting is colored bright green with food coloring gel – remember my tips about food coloring from above!
  • Always make sure that cupcakes are completely cool before frosting them – melted frosting on cupcakes is not a good thing!
  • These cupcakes are double-frosting, the first layer is flattened and rounded off a bit to create the base for lots of sprinkles, and then there is a swirl of frosting on top of that.
  • Use a medium-sized ice cream scoop to add a dome of frosting to each cupcake and use a knife or angled spatula to level it off. This layer is then covered in sprinkles!
  • Use a piping bag fitted with a star tip for the frosting swirl.
  • If you feel like you are going to be making a lot of cakes and cupcakes in your future, I think it is worth investing in a set of piping tips so that you know you always have the right ones on hand for a recipe.
  • Do not overfill the piping bag with frosting, and make sure you squeeze the frosting down the bag to expel any air bubbles.
  • If you are not confident with your piping skills you can practice on some parchment paper first and scoop the frosting back into the bag to use on the cupcakes.

How To Make Unicorn Cupcake Decorations

If you can’t get the ready-made unicorn decorations you can make them yourself using fondant.

Fondant Tips

If you have never worked with fondant before, don’t panic – it is really easy to use, follow my tips and you’ll be just fine!

  • Line a cookie sheet(s) with parchment paper to place the fondant pieces on to dry.
  • Dust your work surface with powdered sugar so that the fondant doesn’t stick. Think of it like the way you use flour when rolling out dough.
  • Rub a little powdered sugar into your hands and knead a handful of the fondant to make it more pliable before rolling, rather than using straight from the package.
  • Dust your rolling pin too, and roll fondant to about ¼” thick. Some fondant rolling pins have guides you can use. You don’t want it too thick as it will take ages to dry, and you don’t want it too thin as it will become more tricky to work with.
  • If there is excess powdered sugar on the pieces, you can gently brush away with a pastry brush, or an unused, clean paintbrush.
  • Alternatively, you can use a vodka spray. Pour some vodka into a mini spray bottle and gently mist the fondant wings. Vodka dries quicker than water which is why it is usually used when handling fondant.
  • Always make extra pieces – that way if some break or you have another mishap, you have got backups that you can use.
  • Leave the cut fondant pieces to harden in a cool, dry place – do not place in the fridge.
  • The fondant pieces should be solid enough to handle and insert into the cupcakes after 3 – 6 hours. I personally leave fondant pieces to dry for around 24 hours. How long this takes, however, is based on the size and thickness of the fondant, and how humid your house is, so judge best if they will hold up as they need to in the cupcakes.
  • When making cakes or cupcakes that use fondant decorations I like to make them a few days ahead of time which allows for drying without the stress. Fondant that isn’t dry enough can mean disappointing end results.
  • After using fondant the surface will be super sticky (it always is in my experience!) so you will probably have to wipe away the sugar first, then give it a soapy hot wash over and then another clean over! You can always by a fondant rolling mat for easier cleanup!

Unicorn Ears

  • The ears are made with two small (different sized) circles of fondant
  • Each ear has one large white fondant circle and one small gold fondant circle.
  • The circles can be cut using the wide ends of two different size piping tips.
  • Alternatively use plunger cutters to cut the circles out.
  • Carefully pinch the bottoms together to form the ears
  • Make extra ears just in case any break!

Unicorn Horns

  • For the unicorn horns, use a silicone mold and press fondant into the cavity. Pop horn out and leave to dry.
  • When they are completely dry you can use gold edible spray to color the horns.
