How to Make a Leprechaun Hat Rainbow Cake
Spray the cake pans with baking spray and then preheat the oven to 350 degrees.
In a mixing bowl, beat together the cake mix, milk, eggs and butter until combined.
Split the cake batter between 6 mixing bowls.
Split the batter evenly between the 6 mixing bowls.
Add in a few drops of food color into each bowl to make the colored layers of the cake.
Mix the batter and colors together until the colors are combined.
Pour the red batter into one cake pan, the orange into a pan, etc.
Bake the cakes in the preheated oven for 21-25 minutes or until a toothpick comes out clean.
Allow cakes to cool completely before removing the cake from the pans.
Once the cakes are cooled, remove the cakes from the pans and using the cake leveler, cut the domes off of the cakes to create even slices.
Make the Frosting and Assembling the Cake.
Using a mixer, beat together all of the frosting ingredients until smooth and the icing starts to form stiff peaks. This takes about 5-7 minutes.
Using a standing mixer, beat together all ingredients until smooth and stiff peaks form, about 5-7 minutes.

Place the blue cake layer on top of the frosting and scoop another 1 cup of frosting onto the cake layer. Spread the frosting out evenly.
Repeat with the green, yellow, orange and red layers.
Spoon 2 cups of the frosting into a medium bowl and mix in several drops of black food coloring.
Add the black frosting into the piping bag fitted with a medium star tip.
Scoop 1 cup of the frosting into another small bowl and mix until combined several drops of gold gel food coloring until it is well combined.
Spoon the gold frosting into a piping bag that is fitted with a small star tip
Using the remaining frosting in the mixing bowl, mix in a few drops of the kelly green food coloring.
Scoop the green frosting into the large piping bag fitted with the large star tip.
Now Decorate a Leprechaun Hat Cake
Place the cake onto the serving board and using the green frosting, pipe an edging around the bottom of the cake board to create the bottom part of the hat
Black frosting – pipe the belt buckle all around the hat.
Green frosting again – pipe dollops of green frosting all over the cake until completely covered.
Gold frosting – pipe the buckle in the front and center of the black belt on the cake.
Place the cake back into the fridge overnight so that you will get a clean cut when you are cutting the cake.
Enjoy!
How to Store This Rainbow Cake
This cake can be stored at room temperature or in the refrigerator. Once the cake has been frosted, store it in the refrigerator overnight so that the frosting hardens. This gives a prettier presentation because it gives a cleaner cut.
Tips for Icing Layered Cakes
When you are icing a cake there are a few things to do that make it a litter easier.
- Always use a cake leveler in order to cut the domes off the cakes. This helps the cakes to sit more evenly.
- Using an ice cream scooper, scoop about 1 cup of frosting onto each layer. This is enough frosting to cover the cake layer and have a little extra to go over the edges. This frosting is used to create the crumb coat on the cake.
- Use an angled spatula for frosting the cake. The angle makes it easier to frost the cake on the sides and the top.
