Scoop out the avocado flesh and add it to a blender along with the cocoa powder, vanilla extract, zero-calorie sweetener, coconut milk, and a pinch of salt. Blend until smooth, scraping down the sides as needed. Add a small drizzle of water if necessary to help the mixture blend. Continue blending until smooth and creamy.

Serve chilled.

Meal Prep Tip: Store leftovers in an airtight container in the refrigerator.
