Mermaid Cupcake Bath Bombs

  • Author: Jocelyn Brown


Make your next bath smell wonderful, fizzy and more relaxing with DIY bath bombs! Try my recipe for Mermaid Cupcake Bath Bombs DIY!




2 cups baking soda

1 cup Citric acid

1 cup cornstarch

½ cup Epsom or sea salt

5 tbsp. coconut oil, melted

13 tbsp. Witch hazel

1520 drops essential oil of your choice 

Mica powder colors in blue, green and yellow


  1. Place the baking soda, citric acid, cornstarch and salt into a large mixing bowl, and stir to combine well.
  2. Add the oil and essential oils to the bowl with the dry ingredients, and mix to combine well.
  3. Stir in the witch hazel a few drops at a time, or use a spray bottle to add it in slowly. Adding the liquid too quickly will cause the mixture to fizz, and will eliminate the fizzing action when it is placed into the bathtub. You want to add enough liquid just until the mixture resembles loose sand that stays together when clumped in your hand.
  4. Separate the mixture into 3 bowls, and add the mica powder coloring to each one. Stir until you have a bowl each of blue, green and yellow mixture.
  5. Place some of the sprinkles into the top of the cupcake mold.
  6. Layer different colors of the bath bomb powder into the mold, and firmly press down to secure it and pack it in as you go.
  7. Continue until you have filled both the bottom and the top half of the cupcake mold, and then press them together firmly.
  8. Let the mold sit for 24 hours, and then remove the bath bombs carefully.
  9. Repeat steps 5-8 to make additional cupcake bath bombs.
