Oatmeal Bath Bomb Projecthttps://www.brambleberry.com/in-the-studio/projects/bath-bombs/oatmeal-bath-bomb-project/PS000154.html
Oatmeal Milk and Honey Fragrance Oil gives these bath bombs a creamy, comforting scent. Cocoa butter adds structure and a chocolatey scent. A touch of oatmeal on top gives the bath bombs a finishing touch.
If you’ve never made bath bombs before, we recommend getting a batch under your belt that does not require a two-part mold. It can be a little tricky to get the perfect molding texture that will stick together and not crumble. A great recipe option for beginners is the Rose Gold Bath Bomb.

Oatmeal Bath Bomb Project
This project is made with oat extract and colloidal oatmeal to create a soothing bath experience.
Stainless Steel Bath Bomb Mold
4 cups Baking Soda (Sodium Bicarbonate)
2 cups Citric Acid
1 oz. Colloidal Oatmeal
4 oz. Cocoa Butter
1 oz. Oat Extract
0.7 oz. Oatmeal Milk and Honey Fragrance Oil
0.6 oz. Polysorbate 80
Witch Hazel in a Spray Bottle
OPTIONAL MOLD PREP: Cylomethicone helps the bath bomb release more easily. Pour a small amount on a cotton ball and coat both halves of the molds. This step is optional, but if you have never used the Stainless Steel Bath Bomb Mold before, it’s recommended.
In a large bowl, add 4 cups of baking soda, 2 cups of citric acid, and 1 ounce of colloidal oatmeal. To get rid of clumps in the mixture, you can push the powders through a sifter or break them up with your fingers. Citric acid has a tendency to take off nail polish, so wear gloves to protect your manicure. Stir everything together.
Add 4 ounces of cocoa butter to a small heat-safe container and melt in the microwave using 30-60 second bursts. Be careful when removing from the microwave as the container may be hot. Add 0.7 ounces of Oatmeal Milk and Honey Fragrance Oil, 0.6 ounces of polysorbate 80, and 1 ounce of oat extract to the melted butter. Use a spoon to fully mix.
Add the oil to the powder and use your hands to mix everything together.
Test the consistency of the bath bomb mixture. The perfect consistency for molding is a texture similar to wet sand and holds its shape when squeezed. If it’s too dry, use one hand to spritz the mixture with witch hazel and one to mix. Below, you can see that the mixture forms a ball when squeezed. This means that the mixture will hold its shape in the mold as well.
Add a pinch of oatmeal to the bottom of one half of the mold. Cover it with bath bomb mixture and press lightly into the mold. Then, scoop more of the mixture on top until it’s mounded in the center. Fill up the second half of the bath bomb, mounding the mixture in the center again. Having loose bath bomb mixture on both sides of the mold and a mound in the center acts as the glue when they are pressed together.
Press the halves of the mold together firmly until they touch. Then, begin to twist and pull the top half off carefully. Once the top half is removed, allow the bath bomb to sit in the bottom half for several hours up to overnight. If they don’t stick together the first time, keep trying. It can be a little tricky to get the bath bombs to stick together, but practice makes perfect!
Repeat the process with the other bath bombs. When they’re unmolded, allow them to sit for 24 hours before using or wrapping in plastic wrap to protect them from excess moisture. Enjoy!
