Instructions

1. Stir the baking soda, citric acid, and coconut milk powder together in a large mixing bowl.
2. Use your fingers to squeeze out any clumps out of the dry mixture.
3. In a separate small bowl, mix the coconut oil with the essential oil. Drizzle the liquid mixture into the combined dry ingredients while stirring with a whisk.
4. Break up any remaining clumps with your hands and make sure the mixture is completely incorporated. The mixture will have a similar consistency of wet sand.
5. Squeeze a portion of the mixture into a ball shape with your hands. If it crumbles, spray 3-5 spritzes of witch hazel into the mixture while stirring, then check again. When the mixture holds together easily without crumbling, it’s ready.
6. Fill your silicone molds with the mixture, pressing firmly as you pack it in. Turn out the bath bomb from the measuring cup or molds onto a sheet of wax or parchment paper. If the bath bombs fall apart, pack them back into the mold and leave them in the mold for 3-5 minutes to set. Then turn them out onto the parchment paper.
7. Allow the bath bombs to air-dry for several hours, then wrap in airtight packaging. You can use plastic wrap or store them in an airtight container.
