Only 3 ingredients!
Place 1 Tbsp coconut oil and 1.5 cups cocoa butter in a double boiler. Heat on low and stir until melty. Remove from heat, gently mix about 5 drops of essential oils in. Pour the mixture into your mold. You can use soap molds or a clean flexible container. If you use a larger container, slice to desired size. Wrap in pretty paper or plastic wrap closed with a cute sticker.
Your body heat (or the heat of the lucky recipient) will melt the oils when you use the bar.
