How to make a unicorn cake

First I followed the instructions on the box to create a complete batter, then split the batter into 3 even amounts. I then colored them in pastel or bright colors.

I then began to pour the batter into 2 9" cake pans. I took a spoon and spattered the batter everywhere to create a tie-dye affect.

I then stuck the 2 cake pans in the oven for the suggested time stated on the cake mix box.

I used the powdered sugar, milk, butter, and vanilla measurements to make the icing. I dyed it a total of 5 colors.

After the cakes were done cooking, I leveled them then stuck them in the freezer to cool.

After they were completely cool, I stacked them and put icing in between to attach. Then I stuck it into the fridge to solidify.

Then I did a crumb coat, to make sure no crumbs spread when the final coat was put on.

While the cakes were in the fridge, I cut out the ears with fondant and covered a waffle cone in white fondant to make the horn.

This is what the horn looked like.

Using this shimmer dust (missed the silver and gold) I coated the horn in it.

After adding a final coat of white icing, I added the horn and ears.

Then the eyes.

Randomly, I piped on the three pastel icing, each with a different piping tip.

This was the final product, I decided to add a mouth to make it more decorative and I sprinkled white shimmer dust everywhere to give everything sparkle. After this I made a few touch ups if needed.
