Grind raspberries in a coffee grinder until you have a very fine powder.
Melt the coconut oil and beeswax (if using) together in a double boiler (I just put the oils inside a glass Pyrex measuring cup, then place whole thing inside a small saucepan. Fill the saucepan with 2 inches of water, and bring to a low boil.)
Add raspberry powder and stir to combine.
Transfer to container with lid and let sit to harden.
Use within 3–6 months. As always, toss it if you notice mold or a change in consistency.
