The Art of Making The Cupcake Bath Bomb! An Easy To Follow Guide

Cupcake Bath Bomb:

It’s easier then you might think to make the cupcake bath bomb. With similar ingredients as many bath bomb recipes, most cupcake bath bombs only differ in having a few extra steps for the “frosting-like” topping.

The frosting topping can be done multiple ways, depending on whether your want extra fizz or more of a bubbling effect when placed in water.

As with other bath bombs, like the galaxy and donut bath bomb, there are tons of ways to customize your recipe for any desired effect. The sky is the limit, however, in this particular recipe we focused more on bubbles, then fizz.

DIY Cupcake Bath Bomb Recipe

Step 1:

Firstly, line your cupcake mold. We use a 6 cupcake mold tray for this recipe. Then, mix all of the dry ingredients for the bath bomb portion together in one bowl. For example, baking soda, citric acid, cream of tartar, kaolin clay and SLSA (which can become airborne quickly so wear a mask for this process, or it may cause you to cough). 

Use a sifter to get out any clumps which may cause issues to your bath bomb down the line, when molding or drying.

Step 2:

Secondly, add in your sweet almond oil, fragrance oil, polysorbate 80, and lake colorant.

Step 3:

Then, add sprays of your witch hazel to get it to the consistency you need. Furthermore, you can tell it’s the right consistency when your squeeze a handful of mix and it stays together in your hand, without crumbling.

Step 4:

Next, add your mixture to a silicone or metal cupcake mold with liners, packing them slightly. It’s okay if it overfills the molds slightly, due to the adding of frosting later.

Set aside.

Tip: Don’t add mixture without liners or your may never get the bath bomb out in one piece.

Frosting Mixture:

Step 5:

Now, using a stand mixer, add your water and meringue powder. Start on slow and begin to blend. Once you’ve got a nice blended consistency going, speed up your mixer to medium for about 60 seconds.

Step 6:

Add the rest of your “frosting” ingredients to the bowl, except colorant. For example, the kaolin clay, SLSA, sweet almond oil, fragrance, and powdered sugar.

Step 7:

Then, begin to mix very slowly, stopping periodically and using a spatula to get the mixture off the sides of the bowl and incorporated into the rest of the mix.

Mix 60 seconds on medium speed.

Step 8:

Add your colorant at this time, and blend until evenly incorporated, about 30-60 seconds should do it.

Tip: There is no exact science to how stiff or thin you want your frosting, it is up to you. Add more water for a thinner consistency of frosting.

Step 9:

Now, configure your frosting tip inside your frosting bag by cutting the end of your bag. Then slide the tip through the hole, to fit snug.

Step 10:

Time to add the frosting. Load up your bag with frosting mixture and place a zip-tie at the other end of where the tip is, so when squeezing the bag, your frosting doesn’t come out the top.

Simply start in the middle of your cupcake bath bomb and pipe in a slow circle outward motion, and then back into the middle to get the frosting to peak.

Additionally, you can use different styles of frosting tips for a unique look.

Step 11:

Finally, allow to dry 48 hours (minimum) prior to use.

Relax & Enjoy!
