DIY Unicorn cake

What a challenge! Let me tell you, it was definitely not easy but I’m so glad I did it.

In order to understand where to start I watched several Youtube videos on how to DIY a unicorn cake, my mom insisted I won’t be able to make it happen and this has just boosted up my motivation to bake this cake. Bakeries in our town charge over 100$ for this kind of cake and in continuous to the ‘low budget 1st birthday’ target, I was focused to succeed with the mission.

I started a night before with the basic chocolate cakes (only because I needed the next morning other birthday preparations, you can check out my post about 1st birthday on a low budget), baked 2 of them in a rounded 20cm diameter mold.

Chocolate cake Ingredients

  • 200 g self-raising flour
  • 40 g cocoa powder
  • 230 g caster sugar
  • 4 large eggs
  • 230 g soft margarine you can also use softened unsalted butter too
  • ¼ tsp vanilla extract
  • 100 g milk chocolate for baking
  • 2 tsp milk

Chocolate cake Instructions

  1. Pre-heat your oven to 160ºC.
  2. Grate the milk chocolate (100g).
  3. Put all of the ingredients into a large bowl.
  4. Divide the mixture evenly and pour half to the mold and spread it out so it’s pretty even (it doesn’t have to be perfect as it’ll even out in the oven, but roughly flat is good).
  5. Put the tins in the oven and cook for 30 minutes. After 30 minutes put a skewer in the middle and check if it comes out clean. If it does it’s done, if not pop it back in for a couple more minutes and check again.
  6. Once cooked, remove the cakes from the oven and leave them to cool in the tins for 10 minutes.
  7. After 10 minutes, remove the cakes from their tins and pop them onto a wire rack to cool completely. Leave in the fridge over night or continue with the decorations.

After the base is done and cool off, straighten the top of both cakes and apply a cream coat between the two so that they will stick together. I recommend using designated baking tools to make it look more clean and professional.

A white fondant would be the perfect coat for the cake. I’m personally not a fan of fondant so I used a simple white cream to cover the cake. If you plan to use fondant you will need 1 Kg of white fondant.

** When working with fondant it is much easier to spread a bit powdered sugar on your work surface.



  • 50 gr white fondant, 10 gr nude fondant, 1 bottle of edible gold paint and a brush.
  • Cut 2 large ear shape of the white fondant and 2 small ear shapes of the nude fondant, color the nude ears with gold paint. Finally use a little bit of water and stick the white and gold ears together.

Gold horn

  • 15 gr nude fondant (depends on how thick/long you want it to be), wood stick
  • Make a ball shape from the nude fondant. Start rolling the ball with your fingers back and forth until you get a long ‘snake’ shape.
  • Roll the snake on a wood stick and color with edible gold paint


  • 15 gr black fondant
  • Make 2 little snakes with the same technique we used to form the horn. You can also create 2 lashes for each eye.
  • Again, to stick all parts together use a little bit of water.

For the unicorn hair I used marshmallows and french meringue ‘kisses’ in several shapes and colors. You can also prepare cream, put it in a bakery bag and make your own kisses with different Piping tips.

Combine it all together!


And this is the final result



Couldn’t be more happy!
