In this article, we will cover the best bath bomb recipe and tips to make the best bath bombs possible.

Ingredients for the Best bath bomb Recipe:

  • 1 cup baking soda
  • 1/2 cup citric acid
  • 1/2 cup Epsom salt
  • 1/2 cup cornstarch
  • 2 1/2 tablespoons almond oil
  • 3/4 tablespoon water
  • 1-2 drops of essential oil (optional)
  • Food coloring (optional)


  1. Combine the dry ingredients. In a mixing bowl, whisk together the baking soda, citric acid, Epsom salt, and cornstarch until they are evenly combined.

  2. Combine the wet ingredients. In a separate bowl, combine the almond oil, water, and essential oil (if using). Stir until they are fully mixed.

  3. Slowly add the wet ingredients to the dry ingredients, stirring constantly. Be careful not to add the wet ingredients too quickly or the mixture will start to fizz prematurely.

  4. If you are using food coloring, add a few drops at a time until you reach your desired color.

  5. Press the mixture into molds. You can use special bath bomb molds or just press the mixture into a silicone ice cube tray or muffin tin. Pack the mixture tightly into the mold to ensure it holds its shape.

  6. Let the bath bombs dry. Allow the bath bombs to dry in the mold for at least 24 hours. Gently tap the mold to release the bath bombs once they are fully dry.

Tips for Making the Best Bath Bombs:

  1. Use high-quality ingredients. The better the ingredients, the better the bath bomb. Choose a high-quality baking soda, citric acid, and Epsom salt.

  2. Mix the dry ingredients thoroughly. It's important to make sure the dry ingredients are evenly mixed before adding the wet ingredients.

  3. Use the right amount of wet ingredients. Too much moisture will cause the mixture to fizz and activate prematurely. Too little moisture will result in a crumbly mixture that won't hold its shape.

  4. Be patient. Allow the bath bombs to dry fully before attempting to remove them from the mold. This will ensure that they hold their shape and don't crumble.

  5. Experiment with scents and colors. The beauty of making your own bath bombs is that you can customize them to your liking. Try different essential oils and food coloring to create unique scents and colors.
