Shirley’s super moisturizing bath bombs

This recipe comes from our in-house DIY bath and beauty expert, Shirley. She’s tested dozens of recipes and this is, by far, her absolute favorite (we love it, too). These bath bombs contain extra coconut oil to make your skin silky smooth, plus, the wetter mixture is much easier to work with.

  • 1/2 cup baking soda

  • 1/2 cup citric acid

  • 1/4 cup cornstarch

  • 1/4-1/2 cup coconut oil, softened in the microwave (20-40 seconds; keep an eye on it so it doesn’t boil over)

  • 20-ish drops essential/fragrance oil; you’ll want to test the strength of the scent as you add the fragrance. Start with 10 drops, then add more as needed. The scent should be strong, since it diffuses in the water.

    • Scents we love: lavender & peppermint, grapefruit & cedar wood, orange & vanilla

  • Colorant (optional). We use cosmetic grade mica powders for a deep, shiny hue.

Combine dry ingredients. If you are adding colorant and want to do a swirl, separate your ingredients into two containers and add the color to one.

Add the softened coconut oil while mixing; you may use the entire 1/2 cup, or you may use less. You’ll stop when the mixture feels like damp sand and begins to clump.


Add fragrance and colorant and mix well.


If you’re creating swirls or adding color to the outside only, press the dyed mixture to the insides of the mold and fill in the remainder with your uncolored mixture. Additionally, you can rub a little coconut oil around the inside of the mold and sprinkle salt, flowers, coffee grounds or any other additive over it until fairly well covered.

Fill molds generously and press together firmly. Allow the bath bombs to set to set for 8–12 hours, or if you just can’t wait, place the mold in the freezer for 30 minutes. Store in a cool, dry place.

Drop your bath bomb into the tub and watch it fizz!
