The tutorial below is the most popular tutorial The Soap Queen blog has ever published. It seems like a perfect tutorial to enter the Birdie Know It All Tutorial contest with. If you haven’t seen this tutorial before, thanks for the visit. If you’ve seen the tutorial, used it and made goodies with it, post a comment below and tell me how they turned out. If you missed the week worth of painful testing to get to this point, here are the trial runs (1, 2, 3).
I used the Wilton Easy Decorating Frosting Kit. Having the extra tips were perfect and made the cupcakes look ultra professional. Two days later, the frosting has dried to a hard plaster-like cast and will easily make it through the mail with proper packing.
2 parts Baking Soda
Additives: SLS (for lots of Bubbles in the Bath) or Bentonite Clay (makes a harder bomb)
4 oz. Citric Acid
8 oz. Baking Soda
1 oz SLS
.25 oz. Caramel Sundae Fragrance Oil
5 drops La Bomb colorant
Witch Hazel in a Spray bottle
Mix Citric Acid and Baking Soda so there are no clumps. Add the SLS or Bentonite Clay. Mix in the fragrance and color. If consistency is not a dry pie dough consistency, spritz on witch hazel until dry powdered product easily sticks together.
For the frosting:
3 Tablespoons Meringue Powder/Powdered Egg Whites
1 lb. (By weight) Powdered Sugar
5 Tablespoons warm water
1/4 tsp Cream of Tartar
few drops Butter Cream Lip Flavor
few drops La Bomb Color

Mix Meringue into warm water first. Add cream of tartar and Powdered sugar. Whip on medium speed for 4 to 7 minutes. Frosting will form stiff peaks and harden within an hour (or so!). To make it smell better, use a dab of Butter cream flavor oil. We used Rosy Pink Lab colors to color our “frosting.”
A strange question: is there any alternative to baking soda in bath bombs?
Since moving, a friend and her husband have discovered that baking soda in bath products makes them itch and break out in a rash. Many bath bomb recipes and tutorials imply that baking soda is just the most convenient and readily available base, but I can find no suggestions for an alternate ingredient, or recipes addressing sensitivities.

The combination of baking soda and citric acid is what makes that fun fizz in the bath tub!
We do have a great Goatsmilk Bath Tea that doesn’t have baking soda in it and would be calming for the skin.

When I first started making bathbomb cupcakes I used this recipe for frosting but have changed to a whipped soap frosting the recipe is on the web under Nizzy’s whipped soap. It is a bit more work but my customers LOVE the use of a floating soap instead of the “throwaway” tops.
Great idea. I love that technique! I see an updated tutorial in my future … =)
Heiress The Diva says
Please add the “one click buy” option for this recipe. Thanks!
We would eventually like to do this for all of our tutorials. Definitely on our to do list. Thanks for the feedback!

Can i add some oils or butters also to the frosting? i would like to make those more moisturize…How much i can add then?
Definitely! Try this recipe that includes Jojoba Oil…but any liquid oil will work in the recipe.
Courtney from Bramble Berry
For this recipe i don’t have SLS. Should i then put some other powder instead of that?
Sindy Anderson says
Hi all, I just made these and it was the easiest thing I’ve ever done~! I guess first time was the charm~ Only 1 problem, My frosting is still a little tacky and it’s been almost 2 days~ Hmmm. Didn’t have any problems with it falling off,just not getting rock hard~ Maybe it’s to wet~?
SLS is Sodium Lauryl Sulfate. It's used in the frosting.
You can get all the ingredients in an easy kit to make the project here:
Or you can get a straight bath fizzy kit here:
so you can master how to make bath fizzies before you move on to adding the frosting =)
this probably sounds silly but ive never made a bath bomb before. what is SLS these look so adorable and i want to make them just need to know what to use lol. thanks
It sounds like mold to me – you could try a preservative (Germaben II and 1% by weight) or try running a fan over the frosting right after you make it so that the frosting dries out faster?
Hi Ann-Marie! I've been using this recipe for bath bombs and have been loving it! My problem is with the frosting… I can get it to pipe.. I can get it to attach to the bomb… but when it dries, it's getting these little dark spots on it. I'm not using SLS or fragrance in my frosting.. just the meringue powder, cream of tartar, water, powdered sugar, baking soda and a little bentonite clay (thinking that the latter may help dry the frosting out more and avoid the brown spots). HELP!! I don't know what to do! I've just made 5 batches of fall fragranced bath bombs, and now ALL of the tops are getting spots! I'm going to have to pop all of the tops off and do it all again… any ideas on how to keep from getting spots???
Elizabeth Clarke says
HELP please! did you ever find a solution for the dark spots in the frosting. I just made 60 of the cupcakes 2 days ago and now they have all dark spots. Please any help would be greatly appreciated
Dark spots on the bottom of the frosting right? We had a few people send us samples and it looked like the discoloring from the fragrance was getting into the frosting and causing spots of discoloration. Could that be what’s going on with yours?
Bathcake, Thanks for the tip. I am seriously frosting impaired (and wonder now about people who frost for a living – do they get really bad carpal tunnel syndrome? My wrists hurt after all the frosting)
RoseHall, I just peel the cupcake liner off before using it but keep it on the cupcakes while they’re in transit. It helps add to their structural stability.
What happens to the paper cupcake liner? Does it peel awar from the finished cupcake?
Here’s an added tip (no pun intended) … if you get the large coupler and the M1 Wilton tip, you’ll get the big fluffy frosting twists like you see in bakeries much easier (still takes a little practice). Also, the jojoba beads make excellent “sprinkles” on top of the cupcakes.
Cali Girl, Citric Acid is a specialty food additive. You’ll find it in stores that sell wine and beer making ingredients or some candy stores since CA is often used for the sour taste in some candies. I hope you can find some by Monday. It sounds like a great present.
Carol, The Meringue does dissolve in the bath but it takes longer than the actual fizzy.
I’m glad you liked the tutorial =)
Teresa R says
Oh my goodness…that’s more beautiful than any real cupcake I’ve ever made!
Does the meringue just dissolve in the bath? These sure look fun to make and I bet more fun to use!
I’m still fighting with humidity problems, which means that bath bombs are a no go. *sigh*
But the tutorial is bookmarked and I will do these… some day…
Oh, my. I just picked up some citric acid from my son to make some lotion. Now I wish I would have taken all he had so I could try this. I have never made bombs before so I didn’t have any ca on hand. He makes wine is why he had it.
I think I will have to call him and tell him to order some for me when he puts in his next order. That will give me time to find the Meringue Powder too.
I am new to your blog and I’m really enjoying it.
Thanks for all of your work you are sharing.
Cali Girl says
do you know where i can go get some citric acid? i would prefer to just go pick it up at a store. i found some recently but it comes in a small container. maybe like a cups worth… i tried to make my cupcakes and they didnt turn out and now i dont have any citric acid left? 🙁
or do you know something i could use in place of it?
i am having some friends over monday and thought it would be cute to give them all a cupcake but i cant even make them.. 🙁
In replace of citric acid, you can use 2 cups of baking powder and 1 cup baking soda and don’t use the other amounts the recipe calls for.
walmart sells citric acid, stores sell it in the baking area, canning area, etcetc health food stores…
