DIY Bath Bomb Recipe

I'll be upfront and honest here. This is the third time I have attempted making Bath Bombs and the first time I have been successful. 

The first two times however were using a different recipe so clearly, my new recipe below holds the magic proportions for making perfect bath bombs that don't end up looking like the photos on - you know the ones I'm talking about.

So, the magic recipe:

1     Tbsp Epson Salt
1/4  Tspn Oil
3/4  Tspn Essence of your choice
1     Dash Food Colouring
2     Tbsp Baking Soda
1     Tbsp Citric Acid*
1     Tbsp Cornflour (or yes, cornstarch)

Mixing Bowl
Sturdy Mixing Spoon
Mould, Muffin Tray or Ice Cube Container

*Citric Acid
Now, citric acid is an ingredient that is super easy to find in any New Zealand supermarket however, it seems it can be really hard to come across in other parts of the world (funny, isn't it?). In place of 1 Tbsp Citric Acid, you can use 1/2 Tbsp of Tartaric Acid. Now, if you do this, please note that your bath bombs will not fizz (kind of the point of bath bombs in my mind but, anyway) They will still dissolve and soften and fragrance the water, they just won't be as fun to drop in the water!


  • To start, into your bowl add your epsom salts
  • To this, add 1/4 Tspn Oil. I've used a soya oil as it's unscented
  • Next, add the essence of your choice. You'll want 3/4 Tspn
  • And the last of our liquid, the tiniest dash of food colouring
  • This is all the liquid that will go into the entire recipe so mix it through well
  • Next in is all your other dry ingredients, 2 Tbsp of Baking Soda, 1 Tbsp Citric Acid and 1 Tbsp Cornflour (or cornstarch)
  • Mix well and what you should have in the consistency and feel of ever so slightly wet sand
  • Into your mould, spoon and firmly press in your powder mixture
  • This recipe will make around 2 large bath bombs or, 5-8 smaller ones depending on the mould being used
  • Once you've got the hang of the mixture, you can either make some more in different colours or up the proportions to make a larger batch
  • Once all set into your moulds, leave these to sit for at least a few hours or, overnight before attempting to remove them
  • The next day, gently pry the dried bath bombs away from the edge of the mould to pop them out
  • After being popped, they may require some further drying before wrapping, gifting or using next bath time
