In a small saucepan, melt coconut oil, maple, and coconut milk  together over medium-low heat. Whisk in carob powder until combined. Remove from heat for a few minutes before transferring the still-warm mixture to a food processor.

Add avocado, collagen,  and salt to food processor and blend until you achieve a silky chocolate fudge. Add in the arrowroot and blend briefly until combined.

Spoon fudge mixture into desired silicone molds and place in refrigerator until set (2 to 3 hours). Remove from molds prior to serving. Store in fridge. You may also use the warm fudge as a topping for coconut milk ice cream or fruit.
