In the bowl of a food processor combine all the ingredients. Pulse the ingredients until smooth. I recommend starting with a few small pulses to avoid any splashing of the milk. Once the ingredients are slightly combined, pulse at a continuous high speed for 40-60 seconds until the ingredients are well combined. Remove the lid. If any of the ingredients are clumpy and sitting on the food processor lid, scrap the pudding into the bowl and pulse again for 5-10 seconds.
Serve the pudding immediately, or chill until desired.
Note: This pudding is best served the day it's made. The avocado will cause the pudding to taste bitter if it's stored for multiple days in the fridge. For an extra special treat, serve the pudding with homemade whipped cream and berries.
