This is probably the girliest DIY I ever made.
And I LOVE IT.
Ever since I saw the first Unicorn Macaroons pop up on Pinterest I knew I wanted to make my own bath bomb version.
As it turned out these cute little magical creatures proofed to be quite the challenge to turn into bath fizzies.
Challenge #1: finding the right mold
I looked at lots of different options, from making my own to using cupcake liners. But I ended up using the next best thing to a macaroon mat, a whoopie pie mold. And it worked great!
Challenge #2: making the ‘filling’
Lots of bath bombs tutorials that use ‘frosting’ have meringue powder in their recipe.
For some reason that idea just didn’t sound very appealing to me. So I decided to go with a bath melt mixture instead. Once it hardens it holds on to both sides creating a beautiful faux bath macaroon.
What I used:
For the bath bomb macaroons:
1/2 cup baking soda – Get it here
1/4 cup citric acid – Get it here
1/4 cup corn starch – Get it here
1/2 to 1 tbsp. rubbing alcohol– Get it here
Whoopie pie mold – Get it here
essential oil (optional)
For the bath melt filling + horns and ears:
1 tsp. rubbing alcohol
Black or dark food or soap coloring – I used a combination of red, blue en green
Gold mica or edible glitter dust (lustre) – Get it here
This recipe makes about 2 to 3 Unicorn Macaroon Bath Bomb Melts, depending on the size of your mold.
If you like this DIY then don’t forget to put a pin on it!
Step 1: make the macaroons halves
Add the baking soda, citric acid and corn starch to a bowl. Mix well to combine all of the ingredients.
Carefully add 1/2 to 1 tablespoon of rubbing alcohol. The amount you need depends on the humidity in the air. I found 1/2 tablespoon too little and 1 tablespoon too much so I added something in the middle.
Fill up your mold with the bath bomb mixture. I used a whoopie pie mold for this. I could make about 6 ‘macaroon’ halves with this recipe. Make sure the macaroons are thick and sturdy enough.
Set them aside to dry. This might take a while and I only recommend starting step 2 until these are completely dry and succesfully out of their molds.
Step 2: make the ‘filling’
To make the bath melt middle part, melt 2 tablespoons of cocoa butter and 2 tablespoons of coconut oil in a double boiler or microwave. Set aside.
In a seperate bowl mix 1/4 cup of baking soda and 1/4 cup of citric acid. Slowly add the melted oil and butter to the dry ingredients. Stir well with a spoon.
For a pop of color I also added a drop of soap coloring to the mixture.
Step 3: create a unicorn macaroon
Scoop out a teaspoon of the bath melt mixture to mold a horn and another one to form the ears.
If the mixture is too liquid you can scoop a few teaspoons in a seperate bowl an set it in the fridge. As soon as you have something that looks like a horn and ears, put them in the freezer to harden. Make enough for all of your bath bombs.
Divide the rest of the mixture over your macaroon halves. Put 1 side on top of the other. Carefully push down. Gently apply even pressure to make sure the macaroon doesn’t break. (Wondering why there’s no third unicorn macaroon in my pictures? Well …)
Get your horns and ears out of the freezer. They should solidify very quickly.
Stick a horn and a set of ears in the soft bath melt filling. Set the entire bath bomb melt macaroon in the fridge to solidify.
I also added some sprinkles to 1 of the macaroons. I really liked the effect but about half fell out so I scratched this plan for the other bath bomb.
As a finishing touch I painted on a face and added some gold edible glitter.
For the face I made my ‘paint’ by mixing a drop of rubbing alcohol with a drop of red, blue and green soap coloring. The idea was to get a dark color and it ended up a dark green. I guess somehow I added more of the green.
For the gold I added a pinch of gold edible glitter to a drop of rubbing alcohol and mixed well. With this mixture I painted the horn and the top of each ear. And that’s it!
Now your Unicorn Macaroon Bath Bomb Melts are ready to use!
