Prepare the molds by putting coffee beans in a single layer on the bottom of the molds. You could also add a cinnamon stick or whole cloves or cardamom pods.

Melt together equal parts of the butter, coconut oil, and beeswax in a double boiler.

When all of the ingredients have melted completely, remove from heat. Add in the essential oils to your desired amount.

Pour a very thin layer that just barely covers the coffee beans into each mold. Return the double boiler to the pot of water to keep it warm and melted. Allow the thin layer to set.

Once the first layer has set, fill the mold until 2/3 full.

Allow the bars to cool and set completely before removing them from the mold.
