Homemade Bath Bomb Recipe

Bath Bomb Recipe - makes 4-5 small/medium bath bombs

1 cup of baking soda

1/3 cup citric acid

3 tbsp cornstarch

1/4 cup coconut oil

Essential oils - I recommend 10 drops of lavender

Spray bottle with water

The first step before you start any bath bomb creations would be to purchase a mold of some sort. You can use any shaped molds but I wanted to get the classic round bath bomb shape, so I purchased a set off of Amazon after looking for some locally without any luck. I have read that you can use silicone molds but I’ve only used my metal molds, so I can’t speak from experience about using silicone. I have made several rounds of bath bombs using the molds I linked to above and love how they turn out.

Making bath bombs is incredibly simple. You mix the dry ingredients (baking soda, citric acid, and cornstarch) together. Then mix the wet ingredients together (coconut oil and essential oils). Lastly, you combine the wet and dry ingredients. I found that using the spray bottle with water works best to wet the ingredients enough to get the bath bombs to stick together without setting off the fizzing reaction. Spray the mixture a few times with water and mix until you can load a test mold with the mixture, press it together and when you pull the two molds apart the bath bomb maintains its shape. I recommend testing your mixture every fews sprays because you want to use as little water as possible.

Pack, press, and remove until you run out of mixture. My recipe makes about 4-5 bath bombs. I like to make about 3-4 batches of bath bombs at a time and mix up the scent with each batch. Set the bath bombs on a baking sheet to dry for 24 hours. These bath bombs are gentle enough for kids to use, but potent enough to use in an adult bath as well. The coconut oil leaves your skin silky and smelling fresh. I was an avid bath bomb tester before making my own and I have to admit that I like my homemade bath bombs far more than anything I bought from a store. Not to mention how cost effective they are to make. My recommendation is to buy the baking soda and citric acid from a bulk store. Someday I’ll get around to pricing the bath bombs out because once I started making them myself I vowed never to buy them again. Stores must make a crazy profit off of bath bombs.

If you’re a mom of a toddler you might like to know that Adler (age 3) loves “helping” me make bath bombs, which mainly results in him being covered in baking soda and putting all the molds in the ingredient bowl. He also loves smelling and choosing which essential oils he’d like in his bath bombs. A really nice mixture he came up with was lavender (5 drops), orange (3 drops) and ylang ylang (2 drops).

Good luck on your bath bomb adventure. Leave a comment if you have any questions.
