In a microwave-safe bowl or using a double boiler, combine your chocolate and coconut oil. If using the microwave, melt it in 30-second intervals, stirring in between until you have a smooth mixture. When using a double boiler, set the bowl over simmering water. Stir constantly until fully melted. If you're feeling adventurous, add in that teaspoon of vanilla extract while melting for a rich flavor infusion.
