Melt all the ingredients except essential oils in a double boiler. You can make your own double boiler by placing a glass bowl over a medium-size saucepan.
Bring the water to a boil until all the ingredients are melted.
Remove the bowl from the heat and let cool slightly.
Stir in essential oils.
Pour the mixture into silicone molds or metal salve tins, whatever you prefer to use.
Let the mixture cool completely and then pop the bars out of the molds.
Store in an airtight container for up to one year.

Notes
This makes approximately 10-15 bars, depending on the size of the mold you use.Store out of direct sunlight and in a cool room. If your house is above 78 degrees, the bars can melt and should be stored in the refrigerator.If you don't have cocoa butter, you can substitute it with shea butter, but the lotion bars will be a touch softer.I have included step-by-step photos and a video tutorial above for visual reference!
