This Avocado Pudding is really easy to adapt, and that goes for making it Keto-friendly, as well.  Simply substitute the sugar for a sweetener such as Stevia, Splenda, Monk Fruit, or Xylitol, and in place of milk use heavy cream. Honey is also an added sweetener and Organic Harmless Honey with 0 sugar can be used (or just add extra carb-safe sweeteners).
