In a double boiler, combine the carrier oil, cocoa butter, shea butter, and coconut oil. Heat gently, stirring until fully melted.
Transfer the mixture to the fridge and chill for approximately 45 minutes until it solidifies to a firm consistency.
Once firm, add your desired essential oils and mix thoroughly.
Incorporate the oatmeal into the mixture, ensuring it’s evenly distributed. For smoother consistency, consider using a mixer. If you use a hand or stand mixer, whip the mixture on medium-high speed until it becomes light and fluffy. This may take a few minutes, so be patient.
Pour the prepared mixture into your chosen container for storage.
