The Best Bath Bomb Recipe

Here is the best bath bomb recipe for you to enjoy. And the best part is that it only takes five easy steps.

Step One: Gather Your Ingredients

You’re going to get your hands dirty. There is nothing more frustrating than getting into a recipe only to realize you forgot one ingredient (brings back cooking Thanksgiving meal memories, yikes).

Step Two: Add the Dry Ingredients to a Glass or Metal Bowl

It’s time to mix. Place 1 cup of baking soda, ¼ cup of cream of tartar, ½ cup of cornstarch and ½ cup of salt into a glass or metal bowl. Don’t use a plastic bowl or aluminum bowl as oils can often react to the mixture and not be effective. Whisk the dry ingredients together.

Step Three: Add Oils and Food Coloring

In a separate bowl, mix 6 to 8 drops of essential oil (optional for a soothing scent) and one tablespoon of vegetable oil (sweet almond oil, coconut oil, or olive oil). Add one to two drops of food coloring (optional) and stir everything together. Next, add that to your dry mixture from step two. Add slowly while mixing in the oils with the dry ingredients.

Step Four: Fill Mold with Mixture

Grab a mold to place your mixture in. If you don’t have bath bomb molds like these, find an empty ice cube tray or any other shaped mold around your home. Using a spray bottle, spritz the mixture with water as you add it to the mold to help compact it into shape. Once this is done, let the mold sit for a few hours. Ideally, this works best if left overnight to allow the ingredients to settle and harden together.

Step Five: Remove DIY Bath Bomb and Enjoy

After letting your mold settle, it is ready to use. Whether you use this yourself or utilize these DIY bath bombs for kids, you’re sure to enjoy all the fun and relaxation of a bath bomb without the box store price tag.

Now Use Those Bath Bombs!

We all deserve some relaxing tub time. Let’s face it, the pressures of life are often washed away as we bubble in our bathtubs and forget the problems of the world.
