Mini bath bombs!

They’re smaller, colorful, and you can customize the scent in each bath bomb, which makes them perfect for little (or big!) kids who love bath time.

I’ve been making a lot of different DIY bath bombs lately, and these mini ones are definitely the cutest! They take the same ingredients as other bath bombs, so if you’ve made any recently, odds are you already have what you need!

How to Make Mini Bath Bombs

Recipe makes approximately 12 mini bath bombs.

You’ll need to gather up your ingredients:

Baking Soda
Epsom Salt
Cornstarch
Citric Acid
Coloring Pigment (optional, but really fun)
Coconut Oil
Essential Oil (also optional, but makes a big difference)

You’ll also need your bath bomb mold. What makes these bath bombs mini is the size of the mold. I ordered this set off of Amazon and used the smallest (1.9″) molds.

To make the DIY mini bath bombs, add baking soda, Epsom salt, cornstarch, and citric acid to a large bowl and stir to combine.

At this point, if you’re only making one color of mini bath bombs, add the pigment to the large bowl.

IF you want to make multiple colors of bath bombs, separate the mixture into different bowls (or coffee cups, like I did) and add the pigment to each bowl.

Dividing out bath bomb mixture for different colors

Stir the pigment into the other ingredients, mixing well.

Add the essential oil to your mixture(s) and stir well. If you’re using 2 or 3 different types of essential oil, add 10 – 12 drops per mixture.

In a small bowl, combine melted coconut oil and water. SLOWLY add this mixture to the dry ingredients and stir gently until combined. It should be similar in consistency to wet sand.

Note about the coconut oil: you can use melted coconut oil (just warm it up in the microwave for 30 seconds) or you can use fractionated coconut oil. Either works great in this recipe.

Pack both halves of your bath bomb mold, over-filling each slightly, then press the halves together, pressing firmly to seal. Allow the mold to set for 15-20 minutes, then lightly tap the sides of the mold with a spoon, then gently remove your bath bomb.

Repeat for remaining bath bombs.

Let the bath bomb sit for 24 hours before storing in a glass container.
