Cocoa Butter Oatmeal Bath Bombs

Cocoa Butter Oatmeal Bath Bomb


420g (51.5%) baking soda
210g (26%) citric acid
130g (16%) epsom salts
14g (1.7%) white kaolin clay
8g (1%) colloidal oatmeal

12g (1.5%) cocoa butter
12g (1.5%) polysorbate 80

8g | 1% essential oil blend (3g lavender, 3g ylang ylang, 2g patchouli)

Dried cornflower petals
Dried rose buds
Witch hazel in a mister, if needed

Tools & Equipment

Aluminium bath bomb mould


  1. Sieve the baking soda and citric acid
  2. Add the rest of the powders and mix well, making sure to get all the clumps out
  3. Melt the cocoa butter and add to the powders along with the other oils
  4. Mix well, getting all the liquids fully incorporated and clump free
  5. Check the consistency of the mixture. It should be like wet sand, so when you squeeze it together it stays in shape. If it’s too dry spritz a little witch hazel and mix.
  6. Add a pinch of dried flowers to one half of the mould and fill until heaped with mixture. Heap the other half of the mould and press the two halves together tightly.
  7. Tap the outside of the mould gently to release the bath bomb and carefully remove from the mould.
  8. Set aside to dry and repeat until you run out of mixture.
  9. Let the bath bombs dry for a few days in a warm, dry place (away from moisture or humidity) Because these bath bombs have a high oil content they can take a little longer to dry compared to basic bath bombs.
  10. This recipe makes about six bath bombs.
  • You can substitute the essential oil blend for any blend or fragrance you like
  • You can add colour if you like – because this recipe has polysorbate 80 you can use any mica colour, or our ZeBomb!
  • You can substitute the cocoa butter for another butter such as shea or mango.
