How to Make Cupcake Bath Bombs + Foaming Bath Whip Frosting Recipe
This post may contain affiliate links.

Learn how to make cupcake bath bombs and get a foaming bath whip frosting recipe that's made without meringue powder.  I made rose gold bath bomb cupcakes with a fun jelly bean essential oil blend.  

I'll be the first to admit that bath bombs aren't my favorite things to make.  I've had a few failed batches, mainly due to crazy high humidity in my house.  

Now that I've made several batches with no failures, I wanted to get into some fun recipes that move a little further from the basic round bath bombs.  

To be honest, I still don't like making round bath bombs.  I'd rather use a single mold or even a silicone mold.  



Learn how to make cupcake bath bombs with a mini cupcake tin—no special equipment needed!—and make a foaming bath whip frosting to top them.

You can make large cupcakes if you want.  You'll probably want to double or triple the recipe because this only makes 8 mini cupcakes.

How to Make Cupcake Bath Bombs + Foaming Bath Whip Frosting Recipe


My daughter loves rose gold and glitter, so we made rose gold and glitter bath bombs.  She wanted a fun scent, so we made a master blend of essential oils that smell like jelly beans.  That recipe will be below.



Cupcake Bath Bombs


For the bath bombs, I used a fairly basic recipe.  It has a 2:1 ratio of baking soda and citric acid to create the fun fizzing and bubbles that bath bombs are famous for.

I also added kaolin clay to harden the bath bombs.  Since I used a mini muffin tin, I didn't want them to crumble when I unmolded them.  

I added pink Himalayan salt to harden the bath bombs and coconut oil to help support the dry ingredients.

Polysorbate 80 is an emulsifer.  If you don't use it, the mica and oils will sit on top of the water.  Your cupcake bath bombs won't fizz as much and the colors won't disperse in the water.  It can also cause a ring around the tub.

Glitter


It's important to use a body safe gold and pink glitter for this recipe.  Other glitters can be irritating, especially in your eyes.  You can always omit the glitter if you want.

I really like using a biodegradable glitter in my DIY beauty recipes.  I have a septic system, so I want to be careful about what I use.



Foaming Bath Whip Frosting 


I usually make whipped soap from melt and pour soap.  This is a great technique that makes a light and fluffy soap.  

However, for this foaming bath whip frosting recipe, I need something that will harden on the bath bomb.  

I picked up some whipped soap base to try using that for a frosting.  After some experimenting, I found that the whipped soap base along with a melt and pour soap, glycerin, and arrowroot powder was the perfect combination for making a bath bomb frosting that hardened when it dried.

I'm going to keep experimenting with using just melt and pour soap, but for now this is what I'm using for cupcake bath bombs.

I got my whipped soap base on Etsy.  It's vegan and available in quantities from 4 ounces to 2 pounds.



Essential Oils


My daughter wanted a fun essential oil blend, so we looked at my fun essential oil blends that smell like candy.  She liked jelly bean, so we made that.

To make a jelly bean essential oil blend combine the following:

I combined them in an empty dropper bottle to make a master blend.  Then I added the necessary drops to my recipe.

You can use 10 to 20 drops for the bath bombs and 5 for the foaming bath whip frosting.  I use potent high quality oils from Crafty Bubbles and Simply Earth, so I used 10 drops for the bath bombs.
