This recipe is so simple! There are tons of variations online that use things like powdered milk and cream of tartar…and they’re all good as well, but this is my favorite. It's not only a great treat to make for yourself, but an easy and affordable gift to make for friends and family!
To make your own fizzing green brain bath bomb you will need:
- 1/4 Cup Baking Soda
- 1/4 Cup Citric Acid
- 2 Tablespoons cornstarch
- 2 Tablespoons coconut oil, melted
- 8-10 Drops essential oils in the scent of your choosing (I like lime and coconut)
- Food coloring
You will also need a brain mold.

Step 1: Mixing It All Together
Start by first mixing together your baking soda, citric acid, and cornstarch. If you’re adding in coloring, now is the time to do it. Squeeze in a few drops at a time and mix to blend. You can do this either in a food processor or by hand. I do it by hand and it’s faster and easier than trying to use a spoon.
Once you have the color you like, slowly drizzle in your essential oils and again mix.
Add your melted coconut oil last and again, drizzle it in slowly, mixing constantly. The idea is to get your mixture just damp enough that it clumps together when you squeeze it but still crumbles with a little pressure. Do NOT add too much liquid as your bombs will not stick together well and you run the risk of starting the chemical reaction early. Your ideal texture should be somewhat like damp sand.
Once you bombs are completely mixed, fill your molds and press it in tightly. You want to pack the molds as tightly as possible. I use the back of a spoon to really smash it down into each nook and cranny.
Set the bombs aside to dry in their molds for at least 24 hours. Once 24 hours has passed, gently remove the bombs from their mold and allow them to continue to air dry for at least one more day.
Step 2: Let's Get Fizzy, Child!
Once they’re fully dry, either share them with your friends (ha ha, right…) or hoard them all for yourself and enjoy your next luxurious bath surrounded by the fizzing citrus decadence that is our homemade bath bombs.
P.S. For a truly twisted treat…I like to stuff a plastic spider into the center of each brain as I’m molding them when I make these for ‘friends.’ As the brains fizz and dissolve…the spider is released and floats to the surface of the water.
