In a saucepan (or in a double boiler that you rig up, such as mine pictured above with a glass jar sitting in a saucepan with about an inch of water), heat the coconut oil and cocoa butter until melted.

Pour the melted mixture into a container and stick it in the fridge for a while until it firms up and hardens.

With a hand mixer, whip the mixture until light and fluffy. Make sure to store it in a cool area. If it gets too warm and melts, simply place the homemade cocoa butter lotion back in the fridge and re-whip once it has cooled.
