Bath Bomb Recipe

Bath Bomb Recipe

There is something so relaxing and comforting about taking a bath in lovely soft, scented water. Another plus for me living in Minnesota – where the temperatures have been below zero for more than a week! – is that it’s warm. Yay for warm!


  • Spray bottle for extra water or witch hazel
  • Large bowl – I use metal so the essential oils aren’t absorbed into the bowl
  • Small bowl – metal for the same reason
  • Molds – silicone molds, muffin tins, or metal bath bomb molds.

Bath bombs


  • 8 ounces Baking Soda (about 1 cup)
  • 4 ounces Citric Acid (1/2 cup)
  • 1/2 cup (4 ounces) Sea Salt or Epsom Salt
  • 4 ounces Cornstarch (about 3/4 cup)
  • 2 tablespoons oil of choice. I use Grapeseed Oil because it has virtually no scent and I always have it on hand. You can use another oil like olive oil, almond oil, coconut oil, argan oil or apricot oil.
  • 2 teaspoons witch hazel (or water) plus a little more if needed
  • 30-40 drops of Essential oils or powdered dried herbs like ginger, lavender, cinnamon, etc.
  • Coloring optional - use food grade colorants


  1. Combine dry ingredients (baking soda, salt, citric acid, and cornstarch and herbs if you are using them) in the large bowl and mix well until combined.
  2. In the small bowl, combine the oil and witch hazel and stir well. Add essential oils if using.
  3. Add the liquid ingredients to the dry ingredients a few drops at a time. Mix well with hands (wear gloves if you have sensitive skin).
  4. Mixture should hold together when squeezed without crumbling. You may need to add slightly more witch hazel if it hasn’t achieved this consistency yet. I recommend using a spray bottle with additional liquid to evenly add.
  5. Quickly push mixture into silicone molds, silicone muffin tins or any other silicone container. You can use other containers if you grease them. Press in firmly and leave at least 24 -48 hours until hardened. If it expands some you can push it down into the mold several times while it is drying to keep it from expanding too much. Using metal molds will create a stronger and more effective final bath bomb but you will need to grease them.
  6. When dry, remove and store in airtight container. I don't know how long they keep for because with two little girls in the house they get used fast.
