Place the avocado (or shea or mango butter) in a mixing bowl that's on the taller and narrow side. I like using a 4-cup pyrex measuring pitcher.
Butters can vary pretty widely as far as how soft or hard they are - you want a butter that's on the softer side for this recipe.
Begin mixing the butter, gradually increasing speed until it's light and fluffy.
Add the oils and mix them in briefly, then add the rose clay, tapioca starch (if using), and essential oils.
The rose clay adds a pale pink tint to the body butter. It's fine to leave it out if you don't have any; your body butter will just be white instead of pink.
For scent, you can use all rose absolute, or all geranium rose essential oil, or combine the two. Geranium gives a nice rosy scent at less cost than rose essential oils.
Resume mixing, starting on low then gradually increasing speed.
Beat until the body butter is light and fluffy. If needed, add a little more oil at a time for a softer body butter.
The texture of the finished body butter reminds me a bit of buttercream frosting when it's ready. (But, don't eat it!)
Spoon into containers and cap tightly.
This recipe makes plenty to share! It will fill 3 to 5 four-ounce jars, depending on your mixer strength and type of butter used.
Shelf life is at least 6 to 9 months, or as long as it smells good. Body butter deflates over time, but you can whip it back up with your mixer at any time.
Use wherever you have dry skin - knees, elbows, feet, hands, or smooth all over. For best results, apply at night after a bath or shower to help seal in moisture.
