Soak pitted dates in warm/hot water for 10 minutes, to soften.
Combine all ingredients into a high-speed blender or food processor. Start with 1/2 cup of milk and add more as needed to thin it out. I used cashew because it’s what was on hand, but coconut, almond or regular milk would also be just fine.
Process for a while, until you get a creamy, caramel-like consistency. You may need to scrape it down with a spoon here and there.
Store in an air-tight container in the fridge for up to one month.
