A clear glass canister filled with homemade lavender bath bombs.

My kids love using bath bombs for their nightly baths. I had been buying lavender-scented bath bombs to help the girls relax before bed, but noticed the cost was really adding up. Bath bombs at stores like Lush and natural grocery stores run around $4.00 to $8.00 each. So I set out to make my own bath bombs that are natural, therapeutic, calming, and more affordable.

These fizzies took about 5 minutes to mix up and now we have a big jar of about 30 beautiful homemade bath bombs by the tub. That would have cost around $100 to buy! These make great gifts too. If you’re into wellness and self-care, you’ll definitely want to add some lunar-charged Moon Water to your bath.

After researching many recipes, I found that bath bombs are usually made with corn starch. I did not have any, and it turns out it’s not necessary. My bombs turned out very fizzy and held together without it. The essential ingredients for bath bombs are citric acid and baking soda. Body oil binds the mixture together and softens skin in the bath. Essential oils make the bath wonderfully fragrant and have many health benefits. Citric acid can be found at some stores in the canning aisle, but it was easier for me to find on Amazon here. I used this almond oil and also use it as a natural moisturizer. We added some lavender flowers since they grow in our backyard. You could also add some food coloring or dried orange zest to fancy up the bombs.

You can use any essential oils you like for your bombs. I used a mixture of lavender and Frankincense for a calming, cleansing, protective bedtime mixture. You can email me about the oils I have and lavender essential oil is also available on Amazon.

Mix the ingredients together with your hands or a rubber spatula until it just holds together like a damp sand when squeezed.

Really pack the mixture down as firmly as possible into silicone molds. I used silicone ice cube trays like this one and it worked perfectly and the bombs are just the right size.

How to make bath bombs without cornstarch.


  • 1 cup citric acid
  • 1 ½ cups baking soda
  • ½ cup almond oil or coconut oil
  • 8-10 drops essential oils
  • silicon mold or ice cube tray


  1. In a medium bowl, whisk together the citric acid and baking soda. With a spoon or spatula, mix in almond oil and essential oils. Mixture should just hold together when pressed between fingers.
  2. Press mixture into your molds so that it’s firmly packed. Let dry for 24 hours. To speed up the process, you can put the silicone molds into the oven. Bring the oven to 200 degrees F and then turn it off and let the bombs sit in the oven, with it off, for an hour, then cool completely before carefully removing. If bombs don’t yet hold together, let dry longer.
