Dry Ingredients

Wet Ingredients



  • If making your own dried lime or orange peel, grate the rind of two limes or two oranges with a zest grater. You can also use one of each. Cover a cookie sheet with unbleached parchment paper. Evenly spread the rind on the parchment paper. Bake at 200 degrees for 30 minutes and allow to cool. Set aside.
  • In a large bowl, place all the dry ingredients. Mix well with a whisk or large spoon, making sure to remove any lumps.
  • Melt the coconut oil in a small saucepan on low heat. Slowly add the oil to the dry ingredients. If you notice a bit too much fizzing of the dry ingredients, add the oil even slower. Whisk gently.
  • Add the water and your essential oils. Again, whisk as you go, always adding the wet ingredients slowly. NOTE: if using vanilla extract instead of vanilla oleoresin, use 2 tsp of water instead of 3 tsp.
  • Once the mixture is ready for your molds, scoop approximately 1 tablespoon of the dried orange or lime rind into one half of your bath bomb mold. Make sure the dried lime is on the bottom so the bath bomb will have the dried fruit as a pretty garnish. This step is optional however. Tip: greasing the molds slightly with coconut oil will make the bath bombs easier to remove later.
  • Then, add the bath bomb mixture to your mold. Firmly pat the mixture to conform to your mold, slightly overfilling it. Do the same with the other half of the mold, omitting the dried fruit on the bottom. Put the two sides together and press firmly, allowing the excess mixture to fall back back into your mixing bowl.
  • Place your molds on a cookie sheet or cutting board covered in parchment paper to set. Don’t leave the bombs in the mold too long or they will be difficult to remove. If you remove them too soon and they crumble, simply place them back in the mold and give them more time to set. We determined that 1 - 1 1/2 hours of curing time is the magic time frame for this recipe.


Caution: please use only steam-distilled lime essential oil in this recipe. Regular lime essential oil has photosensitizing properties that can lead to burns, skin damage, and irritation.
We use stainless steel bath bomb molds instead of aluminum molds for all of our bath bomb making. Not only are stainless steel molds far more durable, but we prefer to avoid aluminum where possible due to its link to Alzheimer's and other health issues. We also don’t recommend using plastic molds, which are easily cracked and not very eco-friendly.
