Add peanut butter, starting with lower end of range (2 Tbsp as original recipe is written) and adding from there to desired taste.
*You can sub 1/2 can coconut cream in place of the cream from 1 can coconut milk.
*NOTE: Not all coconut milk is equal. The brands I know and recommend are Thai Kitchen, Trader Joe's (coconut cream, canned), and Whole Foods 365. Other brands source coconut milk from other regions of the world where the coconuts mysteriously have different fat make-ups, which can (and often do) affect the consistency of this mousse.
*Nutrition information is a rough estimate.
*Prep time does not include chilling coconut milk overnight.
