Recipe For Perfect Bath Bombs From Scratch

If you don’t want to formulate your own bath bomb recipe, the following formula is an excellent one to use. This recipe makes 9-10 large 3” bath bombs that are hard enough to ship cross country. If you want to use less fragrance oil, add an equal amount of carrier oil to make up the difference. You may use any mold of your choice. Smaller molds will yield more bath bombs.

Melt the cocoa butter and shea butter or mango butter in a microwaveable bowl or 4-cup Pyrex measuring cup for about 3 minutes on high power, or until melted, stirring midway through. Alternatively, melt the butter mixture in a double boiler on the stove top. Set aside to cool briefly.

Bath Bomb Recipe Using Bath Bomb And Fizzy Base

If you want to make bath bomb making even easier, try using our Bath Bomb and Fizzy Base. To assist with unmolding, its best to add a little extra butter to these bath bombs. Cocoa butter will give you the hardest bath bombs, but shea butter and mango butter make nice bombs, too. This recipe makes 7 x 2.6” bath bombs. Using a larger mold will yield fewer bath bombs. A smaller mold will make more bath bombs.

How To Mold Bath Bombs Using Any Recipe

The technique you use to mold your bath bombs depends on which mold you choose. We sell three types of round Bath Bomb Molds. The Perfector is good for making tiny bath bombs quickly. Our Plastic Bath Bomb Molds are a great choice if you want protective displayable packaging for your bath bombs. The rigid plastic also holds the shape of the bath bombs while they dry. Our stainless steel molds are the fastest way to make bath bombs that are perfectly round.

No matter what mold you choose, take a moment to check the consistency of your mixture. It should hold together when clumped.

Bath Bomb Recipe and Molding Guide Section 3a

All bath bombs take a little practice to make. Make a couple of practice bombs to familiarize yourself with the technique. Gently toss the bath bomb between your hands to see if it holds together. If it cracks apart, add a dash of isopropyl alcohol to your mixture. If it deforms or seems mushy, add a little baking soda. Once your mixture is the right consistency, you are ready to mold your bath bombs.


Molding Bath Bombs Using the Bath Bomb Perfector

To make scooping easier, transfer your mixture to a narrow bowl. To mold the last couple of bath bombs in your batch, you may want to transfer the remainder to a small cup. Scoop up a generous amount of mixture with the Perfector.

Squeeze it tight.

Bath Bomb Recipe and Molding Guide Section 3bb

Clean the edges of the mold with your thumb. Tap on the mold using a metal spoon or butter knife. This loosens the bath bomb in the mold. 

Bath Bomb Recipe and Molding Guide Section 3bc

Release the bath bomb into your hand. Set it aside to dry.

Molding Bath Bombs Using Stainless Steel Molds

Heap each half of the mold with your bath bomb mixture. Do not press the mixture or pack it down. 

Bath Bomb Recipe and Molding Guide Section 3ca

Cram the two halves of the mold together. Do not twist. Clean the edges of the mold with your thumb. Hold the mold in one hand and use your opposite hand to give the mold a little squeeze.

Bath Bomb Recipe and Molding Guide Section 3cb

Remove one half of the mold and set aside. Invert the bath bomb into your palm and remove the other half of the mold.

Bath Bomb Recipe and Molding Guide Section 3cc

Set the bath bomb aside to dry.


Molding Bath Bombs with Plastic Molds

Gently press some of the mixture in one half of the plastic bath bomb mold.

Bath Bomb Recipe and Molding Guide Section 3da

Mound a little more mixture in the center of the bath bomb. Clean off the edges of the mold using your finger.

Bath Bomb Recipe and Molding Guide Section 3db

Repeat with the second half. (Note: make sure you are using the corresponding half of the mold!) Press the two halves together.  Line up the eyelets and snap the mold shut. 

Bath Bomb Recipe and Molding Guide Section 3dc

Repeat with the remaining molds. Allow the bath bombs to sit on the counter top for two hours. Unsnap the covers and clean the edges with a paper towel, if desired. This step is not necessary, but it does make a smoother presentation. 

Bath Bomb Recipe and Molding Guide Section 3dd

Allow the bath bombs to dry with one half of the molds removed for two more hours or overnight. Replace the covers, or remove the bath bombs from the molds.




Drying, Storing and Shipping your Bath Bombs

Bath bombs are vulnerable to deforming on the bottom during the first hour after molding. If you don’t mind your bath bombs having flat bottoms, you can set them on a baking tray to dry. If you want your bath bombs to be perfectly round, you will need to provide them with some form of support. If you use the plastic molds, you don’t need to worry about your bath bombs deforming; the mold will support them. For bombs made with the Perfector or Stainless Steel Molds, you have a couple of options. You can pour a layer of baking soda on a tray and create a small divot for each bath bomb to rest in. This method works well, but is very messy. Egg crate foam is another option, but you will still experience some deforming. Most recently, I have had the greatest success using a muffin pan lined with plastic wrap. Don’t pull the plastic too tight - you want to create a little hammock for the bath bombs to rest in while they dry. For small bath bombs, try using mini muffin pans. 

Bath Bomb Recipe and Molding Guide Section 4a

Dry your bath bombs overnight. To store your bath bombs, place them in a plastic sweater box lined with egg crate foam. To keep your bath bombs safe, pack them in shoulder to shoulder. If there is space left in the box, stuff it with crumpled paper, a sheet or tissue paper. Store your bath bombs away from direct sunlight in a dry place. Well-made bath bombs should last about 6 months. You may choose to shrink wrap your bath bombs to protect them. 

Bath Bomb Recipe and Molding Guide Section 4b

If you have made your bath bombs well, they should be sturdy enough to ship. Wrap each bath bomb in two large pieces of tissue paper and pack them tightly into a box filled with packing peanuts or other packing material. Stuff the box as tightly as possible. If you suspect the box might get wet, enclose your tissue wrapped bombs in a plastic bag. You may want to test ship a few of your bath bombs to a friend before you sell them to customers in faraway places. Bath bombs are not as shippable during the humid summer months.

We hope that this guide helps you with making the bath bombs of your dreams. Once you have mastered the techniques and recipes above, you will find it easy to creatively make all sorts of bath bombs you will love!
