Easy Homemade Bath Bomb Recipe

Updated on July 16, 2015

Cost of a Homemade Bath Bomb?

Using this recipe and purchasing the needed items from Amazon will result in your bath bombs (medium-sized) costing about .40 each!

This will slightly vary depending on the oils you use (some essential oils are more expensive than others), and cost of your molds. Either way, it's far less expensive than purchasing from the store and they're so fun to make!

Cook Time

Prep time: 10 min
Cook time: 4 hours
Ready in: 4 hours 10 min
Yields: 10 medium-sized bath bombs


  • 1 cup Baking Soda
  • 1/4 cup Corn Starch
  • 3/4 cup Citric Acid
  • 1 teaspoon Essential Oil
  • 1/2 teaspoon Coconut, Almond, OR Olive Oil
  • 5 drops Food Coloring
  • 1 teaspoon Water
  • 1 tablespoon Herb leaves, glitter, sprinkles or other, (optional)


  1. Prepare your molds or "resting surface" prior to mixing your ingredients. Just lightly grease whatever you are using (molds, a muffin tin, etc.) with the same oil you are using for your bath bombs. You can choose to line your molds with herbs, flower petals, or other decoration.
  2. Mix together dry ingredients (baking soda, corn starch, citric acid) very well in a bowl. A sitter works best.
  3. In a separate small bowl or cup mix together your wet ingredients (coconut or other oil, essential oil, food coloring, and water).
  4. If you would like to create multiple scents and/or shapes, you can separate your dry ingredients into separate bowls once they have been mixed. As well, mix your wet ingredients in separate containers so that the colors and scents do not mix.
  5. Very slowly, drip your wet ingredient mixture into your dry ingredients while mixing at the same time. Some people choose to use a spray bottle and spritz their wet ingredients onto the dry ingredients. You want to avoid the mixture fizzing as much as possible so pour slowly and mix it together quickly until it forms a slightly moist dough.
  6. Using your molds (muffin pans etc.), take your mixture and fill to your desired amount. You cam make your bath bombs any size you like. If you do not have an enclosed mold or a lid to your muffin pan (or other surface) your bath bombs make expand as they dry and not keep the shape you would like. You can look at the picture provided to see what they may look like if you use a muffin pan with a cover/lid.


  • Depending on the size of your bath bombs and the temperature/humidity of the room, the drying time may vary and can take up to 24 hours. Some bath bombs may be ready in as little as 2 hours.
  • You can add more color, water, or essential oils to reach your desired strength but you do not want your mixture to become too wet. It is good to practice with a small batch to test the intensity of the color and scent.
  • The scent of your oils may smell quite strong when first creating your bath bombs. The scent will likely fade over time and may not smell as strongly once it's put into a bath. You can keep them wrapped in cellophane bags or wax paper to retain the scent for longer.
  • Coconut oil is a very good choice to use but you may also use other oils such as almond or olive. Just keep in mind that some oils have scents that may interfere with your desired scent for your bath bombs.
  • Use a pure essential oil and not a fragrant oil or other scented oil. The label will state whether or not it is a pure essential oil. Although they may be expensive, you need very little for this recipe.
  • If you are unable to locate citric acid in your local store, it can be purchased online at Amazon or other stores. This is also true for essential oils. You will likely find the best deals on Amazon and can likely find the scent or scents you are looking for.

Decoration and Topping Ideas

You can get quite creative when making your bath bombs. Everyone loves their lovely smells and watching them fizz away in the bath. They make really nice gifts and they're fun to make and decorate.

You can even put small items inside of your bath bombs that can be discovered once they're fizzing away!

Some ideas for toppers and decorations could be:

  • tea leaves
  • flower petals
  • herb stems or leaves (such as mint leaves)
  • glitter (remember you will have to clean this up, so just a small amount is good)
  • sprinkles (they will also dissolve in the water so no clean up is needed)
  • small candies (such as peppermints or Skittles)
