Mix all the dry ingredients together in a medium-size bowl. Stir until well incorporated.
Add in the coconut oil, essential oils, vanilla, and food coloring if using. Whisk together until well combined.
With a spray bottle, spray the mixture with water until the ingredients hold together when squeezed in your hands. Only do one spray at a time so it doesn't get to wet.
Prepare your bath bomb molds by greasing them with coconut oil.
If using dried lavender buds or flower petals, put a small amount into one side of the bath bomb mold.
Press the mixture into both sides of the bath bomb molds and then put the two sides together. Rub the excess mixture off the sides and set aside.
Allow the molds to sit for 24-48 hours or until completely dry and then pop out of the molds.
Notes
This will make approximately 4 bath bombs depending on the size mold you use.
If you have trouble getting the molds to release, try tapping them with the blunt end of a butter knife. That will help break them free.
On nights you don't have time for a bath, you can get similar relaxing benefits in the shower with homemade shower bombs or shower melts!
Allow the bath bombs to dry fully before removing them from the molds. If you remove them too early, they may crumble and not hold their shape.
