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!

Watch this easy step by step video tutorial to see how they’re made (video can be watched without sound, just in case you don’t want to share the Holiday spirit with everybody around you 🙂 ).

How to make bath bombs with frosting

What I use:

For the bath bombs:

1 cup baking soda
1/2 cup citric acid
1/2 cup cacao powder

5 – 10 drops vanilla fragrance oil

Witch hazel or rubbing alcohol

Plastic or paper cups

For the frosting:

1/2 cup coconut oil
1/4 cup citric acid
1/4 cup baking soda

Piping tool
Cake sprinkles

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 …

    Thank you! I made these in a leftover mini cupcake containers for my great granddaughters and they turned out very cute! I did add SLSA to the frosting though because they do love their bubbles. The frosting g did not like the shrink wrap though. Lol! But it’s all good! Merry Christmas!

    Does your frosting recipe dry hard??

    1. The Makeup Dummy 1 October 2018 at 17:36

      It does at room temperature – cold temperatures. If it’s very hot where you live I recommend storing them in the fridge.

      I haven’t tried this myself, but substituting half of the coconut oil for melted Shea butter or cocoa butter might help! I don’t think cream of tartar will make much of a difference. I don’t recommend adding beeswax, as the wax would be very hard to remove from your bath tub. I hope this helps!

    Was curious about the cocoa powder in the tub. Does it leave a ring? Or does it just float on top of the bath water? Thanks much for any info on this.

    1. The Makeup Dummy 28 April 2019 at 13:05

      Hi Ernestine, the cocoa powder can leave a bit of a ring in the bath tub, but it rinses off easily.

    I was wondering for the coconut oil are you meaning to use the solid state melted down or to use the liquid form?
