Worlds Simplest Fizzy Bath Bombs Using Kitchen Ingredients

My kids love bath bombs but I can't continue to pay $6.00 per bath so I decided to try this recipe on Easter Monday. Due to the occasion, I used those plastic Easter Eggs that were left over as molds along with my muffin tins as molds. I hear that bath bombs are equally good just dried as a loose powder and separated into little bags.

Ingredients Nutrition

  • 1 cup citric acid (can be found in wine making shops or where you buy canning supplies)
  • 1 cup baking soda
  • 12 cup light oil (canola, olive, sunflower, whatever is handy)
  • 12 cup cornstarch
  • food coloring (optional)
  • scented oil (optional)


  1. Mix all the dry ingredients together in a bowl by hand.
  2. Mix oil and scent together. You can choose to add the food color to oil now OR wait and add it to the mixture after everything else is combined in the next step. (If you add the food color to the oil now you will achieve a more uniform color. If you add to the food color after you have mixed the oil into the dry ingredients in the next step you will get a more speckled effect).
  3. Mix the oil mixture into the dry ingredients and mix very well with a fork. If you did not add the food color in the last step, do so now and mix.
  4. Now for the fun part! You can mix in some dried flowers if you like, I don't because I hate the mess in my tub. Press the bath bomb mixture into molds. In the middle of the bomb you can push in a little bath pearl or small toy or plastic flower (kids LOVE this). I have also tried sprinkling a little bath salt into the mold before you press in the bath bomb for decoration. Dry over night.
  5. Separate from molds and they are ready to drop into your bath! Simple huh!

This is a very easy recipe. I am able to have my 3 1/2 year old assist me in making Christmas and birthday presents for her cousins. Which she really enjoys and the bath bombs are well received. I have found that it makes enough to make 12 in our muffin pan. We have split the recipe in 1/2 to make two different colors and end up with 6 of each.
