Combine all of the ingredients except for the lavender essential oil in a small mason jar. Place the mason jar in a pot that has a strainer in the bottom. This protects the bottom of the jar from breaking.
Fill the pot with enough water to come halfway up the side of the mason jar, and gently simmer until all of the ingredients are melted.
Add the lavender oil, if using, and immediately pour into your container(s) of choice.
Coffee Infused Coconut Oil
Place the fresh, unused coffee and coconut oil into the top of a double boiler. You can also use a heat safe glass bowl perched on a pot.
Simmer the water under the mixture for about an hour to create an infusion.
Strain well with a nut milk bag or coffee filter and discard the coffee grounds.
Notes
You won't use all of the coffee oil for this recipe, but it can be added to other skincare recipes that call for coconut oil.
