What You’ll Need:

1/2 cup Citric Acid

1/4 cup Extra Fine Epsom Salt

ONE: Add baking soda, citric acid and epsom salt in large bowl and mix to combine.

Note: The baking soda, citric acid and epsom salts may form clumps. Sift them through a strainer to break them up.

TWO: Add the Jojoba Oil and essential oil. You may want to put gloves on and work the liquids into the powders with your hands.

THREE: Now split the batch in half. It’s okay to eye ball it!

FOUR: To one container, add the Pink Brazilian Clay. Again, it may be easier to mix in with your hands. Leave the other container uncolored.

FIVE: Depending on the moisture level of the current mixture, spritz the bath bombs with witch hazel. It should take between 8 – 10 spritzes, and the mixture should be wet enough so when you squeeze the powder in your palm, it will stick together. If you don’t have witch hazel, adding a few extra drops of jojoba oil will also help the powders stick.

You want to spray enough so that the powders stick together and aren’t crumbly. Be careful though because spraying too much can cause the mixture to fizz prematurely and ruin your bath bombs!

SIX: Press the mixture into all six of the Tiny Hearts molds and pack it as tight as you can. You want these bath bombs to stick together!

SEVEN: Unmold the hearts after about a half an hour by forcefully hitting the mold on the table. Don’t be afraid about hitting it too hard! Without enough force the hearts won’t pop out. After they’re out of the mold, let them sit overnight to fully harden up.

EIGHT: Once one color of bath bomb is unmolded, repeat steps 5 – 7 with the second color.

NINE: We filled our jars with alternating layers of pink and white hearts, but you can package them however you’d like. Enjoy!

    Those are so cute!

  2. Yay! I have this mold! I’m making these tomorrow!

    • Amanda says:

      Hi there!

      Yay, I’m so glad you’re going to give this a try! If you get photos, we would love to see them on our Facebook page!

  3. Nika J. says:

    Can you use something other than the clay as a colorant? I so want to make these for an event that I have this week.

    • Veronika says:

      You can use any botanical powder, Cocoa powder, Alkanet root powder or fine Pink Himalayan salt for bluish-pinkish color.

    • Amanda says:

      Hi Nika!

      You could certainly use a different colorant, in particular I would recommend the LaBomb Colorants, which are specially formulated for bath bombs and won’t stain the tub or result in colored water!

      Bath Bomb Dyes/ La Bomb Colorants:

      You can also use micas, or like Veronika mentioned, various natural colorants work well too :)

      • Katie says:

        Hi Amanda,
        Do you think the fizzy lemonade colorant would stain the tub? I have some of that on hand from a CP soap recipe.

  4. Shelly says:

    I do not have the clay. Can I use a mica blended with glycerin to add color? Or even add it to my jojoba oil?

  5. Mimi says:

    Can another oil be substituted instead of jojoba. I have everything else….I do have sweet almond oil or grapeseed.

  6. […] Soap – There are lots of specialty soaps that smell great, feel wonderful, and feature aroma therapy. If you want to be really create you can try making your own soap. […]

  7. Terri says:

    This is a fantastic kit! I just made my first batch of heart fizzies and they turned out perfect. I was delighted by the quality of the molds. I am happy to report my hearts turned out just like the ones pictured. The key for me was using a very fine mist spray of Witch Hazel to get the right consistency before molding them.

    • Amanda says:

      Hi Terri!

      I’m so happy you enjoyed making these bath bombs. I made some as well, and love using them in the tub :). I found that a little witch hazel worked well for me as well. If you get photos of your project, we would love to see them on our Facebook page!

  8. Nicole says:

    Hi, I live in the Uk and I am struggling with what oils
    And fragrances to use that will make the bath bombs smell
    Great and give them colour. Also oils and smells that are safe for the
    Skin. Please please could you help!! Lol

  9. Cindi says:

    Can I use a silicone mold for this or are the hard plastic molds needed?

  10. Miranda says:

    Hi! I’m making these as I type this, they are currently drying in the molds. :)
    I have a question though- I have leftover mixture, can this be kept in an airtight container until I make my next bath of molds or does it need to be used right away/thrown out?

    • Kevin says:

      Hi Miranda,
      With the left over mixture, I would use it as soon as possible as it will not stay. I will harden up. I wouldn’t throw it away but try to improvise if you don’t have another mold by just making small round min bath bombs.
      Thanks for your comment. :)

  11. Julie says:

    If you were to sell these heart bombs, how much would you sell them for?

  12. Katie says:

    Do you think the fizzy lemonade colorant from Brambleberry would stain the tub? I have some of that on hand from a CP soap recipe.

  13. Amanda says:

    Hi Katie!

    Most likely yes, it would stain the tub unless you used a very small amount. I would recommend using La Bomb Colorants for your bath fizzies, they are liquid colorants especially made to not stain your tub :) You can also use a small amount of mica in your bath bombs, but if you use too much, it’s possible that it may stain your tub.

  14. Raquel says:

    Hello! I am having major problems trying to make some bath bombs right now. I just bought 10 lbs of Citric Acid and a bunch of fragrance oils from Bramble Berry. I mix the dry ingredients as directed (1 part citric acid, 2 parts baking soda – Arm & Hammer in this case – plus the fragrance oils). When I spray the mixture to bind with Witch Hazel, I hear a fizz (I am going as light as I can with the witch hazel). Should this be happening? Then I mold my bath fizzies and release. All looks good, but I come back to check on them a few hours later and they have bulged and expanded significantly. Is this just a problem with my witch hazel? It says on the label “Witch Hazel USP 86% witch hazel, 14% alcohol by volume” it also says “Hamamelis Water Astringent” (just noticed that part). Maybe I answered my own question, and there is water in my witch hazel. What kind should I buy that will work? And can I use 91% Rubbing Alcohol instead of witch hazel (it did not fizz on my small test sample). Sorry for the long entry, I’m just
    So frustrated right now and would love some input.

    • Raquel says:

      I’m sorry, one more question. Should the mixture feel sticky? Mine does (even with no added oils, colorants or fragrance – just citric acid, baking soda and sprayed witch hazel).

  15. Kristie says:

    I made these the first time and they came out perfectly! I ordered more ingredients, and made a second batch, and am having a terrible time getting them to solidify. I’ve molded them time and time again and they have the consistency of sand. I’ve added almost 4T of jojoba, and still nothing. Ideas?? I don’t want to have to throw away everything if I don’t have to.

    • Amanda says:

      Hi Kirstie!

      I’m sorry to hear this recipe is giving you some trouble! Did you do anything different the second time? Also, did you use witch hazel in your recipe to help it combine? Let me know, I’d love to help you troubleshoot :)

  16. Anna says:

    Hi! I recently made mini bath bombs in a small ice cube tray and used green tea powder and tea tree oil as well as the basic recipe. I used witch hazel to spray the mix together but when I packed it into the mould they rose and almost inflated and I pushed them aback down several times before they rose again. Is there a reason for this or how can I try to avoid it? Thanks x

  17. Amanda says:

    Hi Anna!

    Usually this can happen when too much witch hazel is used. I would try using less next time :). Sometimes this can also occur if you live in an area with high humidity. I hope this helps!

    -Amanda with Bramble Berry

  18. Kristi says:

    When you leave them overnight to harden do you store them in a Tupperware or just leave them out? I left mine on the counter and after about an hour they seemed to be hardening nicely but in the morning they turned into squishy blobs. It looks like they started reacting. We do live at the coast though. Thank you.

    • Amanda says:

      Hi Kristi!

      I have done both methods in the past, and the majority of the time, leaving them out in the air has been fine. Only once have my bath bombs begun reacting, but I live on the coast as well :). To be safe, storing them in a closed container would be a good way to go!

      -Amanda with Bramble Berry

  19. Jodi Chen says:

    Can you tell me how many fit in each 8 oz jar? The recipe says it yields two jars’ worth, but I must be missing the actual quantity of tiny bath bombs this recipe makes…. :) Thanks so much!

  20. Sara Magdy says:

    Can I neglect the epsom salt from the recipe?

    • Kelsey says:

      Hi Sara!

      You can leave the salt out of this recipe. It will change the texture slightly, so you may want to make a small test batch to see if you like the final product. :)

  21. Yanique says:


    Can I use any other clay other than the Pink Brazilian clay listed above? Like sea clay or rose clay…. Thanks for your help.


  22. Kelsey says:

    Hi Yanique!

    Absolutely! Either of those clays would work great in this recipe. :)
