These bath bombs with frosting smell like chocolate and vanilla heaven.
But that’s not even the best part about this DIY.
This recipe is made with common bath bomb (and kitchen) ingredients. Even the frosting contains NO MERINGUE powder, NO POWDERED SUGAR and NO SOAP base.
I use a different secret ingredient that I KNOW you have in your kitchen right now!

How to make bath bombs with frosting
What I use:
For the bath bombs:
5 – 10 drops vanilla fragrance oil
Witch hazel or rubbing alcohol
Plastic or paper cups
For the frosting:
How To make this recipe:
Combine the baking soda, citric acid and cacao powder in a bowl. Stir well to make sure all of the ingredients are mixed together.
To transform these dry ingredients into a bath bomb mixture, I added about 2 teaspoons of vanilla extract. Instead of using witch hazel or rubbing alcohol like you would normally use as your wet ingredient, the vanilla extract has the same effect AND adds a very nice scent to your hot chocolate bath bombs!
Carefully add the vanilla oil to the dry mixture and stir well to combine. Depending on the humidity where you live, you might need to add more or less liquid to form the right consistency.
Slowly add witch hazel or rubbing alcohol to the mixture. Check the mixture regularly to see if it holds together. Add more until the mixture has the right consistency (similar to slightly damp sand).
Fill up 2 to the 3 plastic or paper cups with the bath bomb mixture (depending on the size of your molds). Press the mixture down with your finger tips as you fill your cups. Set the cups aside for at least 4 to 6 hours to let the bath bombs harden.
Once the bath bombs are dry, take them out of their cups/molds.
How to make the special ingredient frosting
Now it’s time to make the frosting.
In a seperate mixing bowl combine 1/4 cup of baking soda and 1/4 cup of citric acid. Add 1/2 cup of room temperature coconut oil. Mix well with a spoon to form a smooth paste.
Scoop the frosting mixture into a piping bag. Pipe the frosting on top of each bath bomb base using the same technique as you would when you are frosting cupcakes. Don’t worry if you have no experience, I have zero piping skills and I still think they turned out pretty 🙂
The frosting will melt a little slower than the “chocolate” base of the bath bomb, because of the oil. The frosting on its own works more like a bath melt.
For fun I decorated my hot cocoa bath bombs with frosting by adding half a cinnamon stick as a “straw” and some cake sprinkles on top.
Set the bath fizzies in the fridge to let the frosting harden. This recipe will only work if your coconut oil is solid at room temperature. If that’s not the case where you live, you can try substituting some of the coconut oil with Shea butter, but I haven’t tried this myself.
Break off a chunk when you are ready to take a bath or drop one entire hot cocoa bath bomb in your bath water to soak into your very own chocolate and vanilla heaven …
