For the bath bomb base:

1/2 cup Epsom salt
1/2 cup cornstarch
Water
Optional add-ins:
Add these ingredients to your bath bomb to boost its aromatherapy and skincare benefits.
2 tsp of an essential oil (or a blend): Lavender, geranium, neroli, peppermint, and sandalwood are all popular essential oils for a super relaxing bath routine. Wanna know which essential oils are best for your skin? We got you—just read our blog post.
2 tsp of your favorite body oil: Nourishing carrier oils like sweet almond oil, coconut oil, and jojoba oil all work great with your homemade bath bomb.
A colorant: To add color to your bath bomb, add in a few drops of food coloring or dry pigment. There are even plenty of options if you’re looking to keep your bath bomb as natural as possible— just use natural, vegetable-based pigments instead.
Visual accessories: Adding in dried flowers, compostable glitter, and edible sprinkles are all fun ways to add that “wow” factor to your bath bomb. Totally Instagram-worthy, if you ask us.
Tools:
2 mixing bowls
A whisk
A spoon
A bath bomb mold: There are molds made specifically for bath bombs that you can purchase. You can also use a muffin tin, a candy tray, easter eggs, or any type of silicone mold. Feel free to get creative here!
How to make your own bath bombs, step by step:
1. In a large bowl, begin whisking the foundational dry ingredients: baking soda, citric acid, Epsom salt, and cornstarch. If you're using a powdered pigment, you'll want to add that in now. If you're using a liquid colorant, wait until the next step.
2. In the second large mixing bowl, combine most of the liquid ingredients: your preferred body oil, the essential oils, and liquid colorant (if that's what you're using). Don't add any water just yet.
3. Now, very slowly add the wet mixture to the dry mixture. The baking soda and citric acid are what cause bath bombs' fizzy effect and that effect is activated by water—so making sure the mixture is not too wet is key to not "setting it off" prematurely. If you see a little bit of fizzing, though, that's OK.
After all of the liquid is well combined with the dry mixture, the texture should resemble damp sand. If you pick some up and squish it together, the mixture should clump up. If it doesn't, add a 1/2 teaspoon of water at a time until it gets to the right texture. Make sure to combine each 1/2 teaspoon thoroughly into the mixture before adding more.
If you have fun additions to your recipe like dried flowers, sprinkles, or compostable glitter, add those in now.
4. Very tightly pack the crumbly mixture into whatever bath bomb mold you're using, making sure there are no air pockets, as this will cause them to fall apart more easily. If you're using a mold made specifically for bath bombs, overpack the two sides slightly and then squish them both together. Allow the mixture to stay in the mold for about one minute. Then, very gently remove the bath bomb from the mold and set it aside on a clean surface (wax paper, a paper towel, or parchment paper all work).
5. Once all of your mixture has been molded, allow your homemade bath bombs to dry out for at least 24 hours. Then store in an airtight container before adding them to your next bath!
