DIY Sprinkle Doughnut Bath Bombs

There is something about pink doughnuts with sprinkles that make me happy. They are just so darn cute! After making pink melt and pour soap with jojoba bead “sprinkles” a few years back, I revisited the idea and made these doughnut bath bombs. The Doughnut Half Mold gives them a cute doughnut shape, while a touch of coconut oil gives the bath water a touch of moisture. They are scented with the sweet Strawberry Fragrance Oil, but feel free to use any fragrance oil you like!

This bath bomb project uses two different types of colorant. The entire bath bomb mixture is colored with Rosy Pink La Bomb Colorant. The term “La Bomb” refers to a type of colorant that’s formulated specifically for bath fizzies; find them all here. They’re made of highly concentrated FD&C and D&C dyes mixed with glycerin. La Bombs are specially formulated to not leave any color on the tub, and won’t make your bath bombs fizz prematurely.

Once the doughnut bath bombs have hardened and are unmolded, the “sprinkles” are painted on using a mixture of micas and 99% isopropyl alcohol. The mica paint dries almost instantly. To help the micas (and coconut oil) disperse better in the water, I added a touch of Polysorbate 80 to the bath fizzy mixture. You don’t have to add it if you don’t like, but it helps prevent pools of oil, micas and glitter from forming in the water.

What You’ll Need:
Doughnut Half Mold
1 cup Baking Soda
½ cup Citric Acid
.5 oz. Coconut Oil
6 mL Strawberry Fragrance Oil
5-6 drops Rosy Pink La Bomb Colorant
Fine Iridescent Glitter

These bath bombs look just like pink doughnuts with sprinkles!
Author:
Recipe type: Bath Bombs
Serves: 6 bath bombs

Ingredients
  • Doughnut Half Mold
  • 1 cup Baking Soda
  • ½ cup Citric Acid
  • .5 oz. Coconut Oil
  • 6 mL Strawberry Fragrance Oil
  • 5-6 drops Rosy Pink La Bomb Colorant
  • Fine Iridescent Glitter
  • Witch Hazel in Spray Bottle
  • Droppers
  • Optional: 2 mL Polysorbate 80
  • Yellow Lip Safe Mica
  • Magenta Mica
  • Super Pearly White
  • Shamrock Green Mica
  • Blue Mica – Cellini Lip Safe Mica
  • 99% Isopropyl Alcohol

Instructions
  1. In a large bowl, mix together the baking soda and citric acid. If there are any clumps in the mixture, you can push the powder through a sifter or break up the clumps with your fingers. Citric acid has a tendency to take off nail polish, so wear gloves to protect your manicure.
  2. Add the melted coconut oil, Strawberry Fragrance Oil, Polysorbate 80 and Rosy Pink La Bomb Colorant. Mix all the ingredients together, until fully combined. I have found it's best to use your hands for this step!
  3. Once the ingredients are fully mixed and there are no clumps of colorant or oil, add the Fine Iridescent Glitter and mix in.
  4. Begin spritzing with witch hazel, while mixing with your hands or a spatula. Continue spritzing until the mixture is a texture that holds its shape when squeezed.
  5. Fill each container with the bath fizzy mixture, pressing the mixture down to make sure it's packed tight in the mold. Make sure to leave the middle of the mold clean so there is a hole in the doughnut shape!
  6. Allow the bath bombs to harden and dry for several hours, up to overnight.
  7. Once completely hard and dry, remove the bath fizzies from the mold.
  8. Time to paint on the sprinkles! In separate containers, add about ⅛ teaspoon of the Super Pearly White Mica, Yellow Lip Safe Mica, Magenta Mica, Shamrock Mica and Cellini Blue Mica with about ¼ 99% isopropyl alcohol. Stir together to create a "paint." The paint should be thin enough to spread, but also saturated enough to leave a strong color on the fizzy.
  9. Using a fine point paint brush, start painting the sprinkles on the fizzy, cleaning your brush between each color. If you find the "paint" is bleeding on your bath bomb, add a bit more mica to the mixture.
  10. Continue painting on sprinkles until you're happy with the look. Allow them to fully dry for several hours. To use, place in a hot bath and enjoy!

  4. Hi,
    Would it be ok to sub food coloring instead of mica? And Would it be ok to sub food coloring instead of La Bomb colorant?

    Thank you for the wonderful recipes!

  5. Hi again,,

    thx so much for checking that out kelsey good to know.have a great weekend !! 🙂

  6. Hi,,
    i made the donut bombs they turned out great.thank you.i do have a question tho is arrowroot powder & arrowroot starch the same? another recipe to add to my growing S/Q collection.lol

  8. Would you say this recipe is for beginners? I would like to get into making bath bombs and soap but not sure where to start.

    • We haven’t tried that emulsifier, so I’m not entirely sure. I would recommend making a small test batch to see if it helps mix the oil into the bath water nicely. 🙂

  10. Hi. My name is amy and I’m completely new at this bath bomb stuff but I got tired of paying almost 10 dollars for each at lush. I follow the instructions on here (even went and bought the glycerin based food coloring), but I just had a couple of questions:

    1. I live in California and the humidity in my house is very high sometimes so it gets really difficult to dry my bombs. I live a mile from the beach and the humidity reaches 97% at times. What can I do chemically to help them dry? (I’ve tried the oven, and unfortunately, it only melted my stuff.)

    2. If I use kaolin clay, how should I add it to the mixture? As in, proportions for baking soda and citric acid are 2 to 1, so is there one for kaolin clay? Would it be a good idea to use kaolin clay?

    I’m also having trouble with texture after mixing, but I’m hoping that after the humidity problem is fixed, so will everything else. I read the bath bomb q&a section but im still confused. Thank you so much! I really enjoy the site. So glad I found it. You are awesome!

    • There are a few tricks to help your bath bombs dry in humid climates! The first is to add less witch hazel when you’re making them. The humidity itself will help the bath bombs hold together. After you’ve mixed the powders, squeeze the mixture in your hand. If it holds it shape, you don’t need any witch hazel that day! If not, spray 1-2 times, mix and test again. Repeat that process until the mixture holds its shape.

      Then, while the bath bombs are drying, it really helps to keep them in a cool, dry place. If you have a dehumidifer that would be ideal. If not, you can place rice or silica packets nearby to absorb the excess moisture. Once they’re dry, wrap them tightly with plastic wrap to protect them from humidity.

      You can use kaolin clay if you like! It helps add structure to the bath bomb. We use about 1 tablespoon per cup of fizzy mixture. 🙂

      Bath Bomb Questions and Answers: https://www.soapqueen.com/bath-and-body-tutorials/bath-bomb-questions-answers/

  13. Hi there! I have a question. When I first started making bath bombs they started expanding/breaking apart and always had weird wet warts on them but fizzed fine in the bath. I later realized whenever I spritzed the Witch Hazel it started fizzing and (I think) activating my bath bombs too soon. So I started using 99% alcohol and different types of oils and they turned out beautiful but a tiny bit sandy and powdery. So my question is could the Witch Hazel be activating them too soon? And is there any way to fix that…?

    • Do you know what the witch hazel was mixed with? If it was mixed with water, that may have been what was setting the reaction off. Water causes the bath bombs to fizz too early. Alcohol, on the other hand, can be a bit drying. We like to use witch hazel mixed with alcohol. That wets the bath bombs without making them fizz or crumble. 🙂

      • I don’t add any other liquid besides Witch Hazel and FO or EO to the citric acid and baking soda if that’s what you mean.

        • I didn’t phrase my question very well, sorry about that. Did you get your witch hazel from us? If not, do the ingredients on the back say witch hazel and alcohol, or witch hazel and water?

          -Kelsey with Bramble Berry

          • Yes, I ordered it from brambleberry. I also ordered more a little bit ago (again from brambleberry) to see if maybe it would be different but it still fizzed the same.

          • Hmm, typically the witch hazel doesn’t cause a reaction. It can sometimes happen if a large amount is used. How much did you use in your recipe? Thanks for answering my questions. 🙂

            -Kelsey with Bramble Berry

          • I think I may have an idea! If the witch hazel is dropped in or sprayed in one area, it can start fizzing in that one area while the rest of the mixture remains dry. That may be what’s causing the warts and crumbling. I would recommend spritzing the witch hazel with one hand and mixing with the other. That distributes the liquid so it coats all the powder. It also prevents one area from fizzing while the rest stays dry. 🙂

  14. Hi there!
    What a lovely tutorial, thank you!
    I’d like to use powdered citric acid rather than granular, would the ratio of CA to Bicarbonate still remain the same? And if I were to use essential oil instead FO would I use the same amount or slightly less?
    Thanks so much!!

    • Thanks Bronwyn, glad you like the tutorial! The powdered citric acid should be the same usage rate as the granular kind. Because it’s lighter, you may want to wear a dust mask to prevent nasal irritation! Also, how much essential oil you add depends on how strong it is. I would recommend starting with 3 mL, then adding from there. 🙂

  15. Another winner! I’ve been waiting for the video–thank you! Am planning on trying it this weekend.
