In a bain-marie, melt down your hard butters and oils until fully liquid
Set in the freezer to harden, about 20 minutes.
Once the mixture is solid again, but not too hard, whip it up using an electric whisk, a food processor with a whisk attachment, or your KitchenAid (lucky you!)If you need to, you can use a hand held whisk, and a lot of elbow grease! :)
Whip about 5 minutes, or until you have created fluffy white clouds. Spoon it into a clean jar or container. It will keep for 3 months.
Slather it on!
