Anyone with tweens can probably relate to the bath bomb craze that is currently in full swing. If you’re not already on board, bath bombs are hard-packed mixtures of dry ingredients which effervesce (fizz and bubble!) when wet. They’re an extra special treat for bath time.
We’re most definitely fans at our house but, just like with anything, bath bombs can either be full of artificial fragrances and other unwanted ingredients or be au naturale. So, this holiday season, we set out to make our very own Homemade Lush Bath Bombs. And that’s because we thought they’d be a super fun DIY gift for friends and grandmas, and (the best part) – we’d know exactly what is in them!
Sponsor Shoutout: Plant Therapy
Just because we don’t want artificial fragrances (or colors) in our bath bombs doesn’t mean we don’t want any fun scents at all! So, we were excited to use some of the holiday essential oils from our lovely sponsor Plant Therapy for this project. Candy Cane bath bombs? Yes, please!
Essential oils have been around for centuries and are concentrated, volatile, aromatic liquids obtained from the fruits, seeds, flowers, bark, stems, roots, leaves or other parts of plants. Plant Therapy offers only 100% pure essential oils and is one of the few companies who offer USDA Certified Organic options. All of their oils go through multiple rounds of testing and are always free from additives, adulterants and dilutions to uphold the highest quality. While you can certainly find many essential oil options out there, know that they are not all made the same, and finding a quality product is essential. Which is why Plant Therapy has been a longtime partner of ours!
As a bonus, new customers can take 10% off of their first order with code 100DAYS10. A great reason to try Plant Therapy!

Homemade Natural Bath Bombs
Ingredients
- 1 cup baking soda
- 1/2 cup citric acid, anything acidic can damage some countertops (especially marble) so be careful!
- 1/2 cup Epsom salt, recommended to me by my chiropractor to help with sore muscles
- 1/2 cup cornstarch
- 2 teaspoons all natural food coloring, optional (natural powdered food coloring activates when wet in the tub and will not stain)
- 2 tablespoons coconut oil, melted/warm
- 1 teaspoon water, do not use more than this!
- 10 drops your favorite essential oil, we used Plant Therapy essential oils
- prizes to go inside - optional!, (we used "Magic Grow Capsules" that expand when wet)
Instructions
In a large bowl whisk together the baking soda, citric acid, Epsom salt, cornstarch and (only if using) powdered food coloring.
In a separate small bowl combine the melted coconut oil, water and essential oils. (We used peppermint, but I’m guessing that this would work great with lavender, sweet orange or chamomile.)
While continuously whisking, very slowly drizzle the liquid ingredients into the dry ingredients until well combined. The outcome (as pictured below) should be similar to a dry, crumbly sand and should not be a "wet" consistency. Warning: If mixture gets too wet it will activate the fizzy part of the bath bomb too soon!
TIGHTLY pack the mixture into each side of the mold then press the two sides together. Ideally let it stay in the mold overnight, then lightly tap around the mold with a spoon to very carefully open and remove bath bomb. Finished product will still be somewhat fragile, so be careful!
A Note about Molds and Gifting: I've read the stainless steel molds work best, so that's what we used with no problems. Bath Bombs (both homemade and store bought) can be fragile though, so we plan to transfer into same-size plastic molds for gifting. Alternatively, you can use a hair dryer on shrink wrap baggies made for the purpose of packaging bath bombs. I ordered a set that includes both options for our gifts this year. Either way, I would definitely make sure the DIY bath bombs are protected before handing them over!
Recipe Notes
The number of bath bombs this recipe will make is approximate. It will depend on the size of your molds.
Simple Balsamic White Bean Dip (+ our GF and DF Team Dinner!)
We have tried several times to make the bath bombs with the metal molds and we cannot get the bombs out of the molds. We have tried using coconut oil and mineral oil to coat the mold, but we still can’ t get them out. Any suggestions? When we do get 1/2 of one out it is very nice, but we want the whole thing.
put the mix very loosely inside the mold over filling both sides and then press them together tightly and wait for them to dry out :)
Place bath bombs in the molds into freezer for 20 mins. Take out and hold in your hand to warm the metal. The coconut oil will melt a bit and allow you to remove the bomb easily.
How big are your medium size molds in diameter? I am trying to figure out how many this recipe could make using my mold. Thank you.
Hi. These are the metal mold sizess: Bomb Mold Kit comes with 3 sizes – 1.8″(2 Set), 2.2″(2 Set), 2.6″(2 Set).
I’ve heard about putting prizes inside, especially if you make them look like pokemon balls. Saw a kid selling those at a school store. So fun to make bath bombs!
First batch didn’t dry together as a ball. Recipe seems good. We may just stick with silicone molds.
