Start by placing your dates in a 4 cup (1 litre) measuring cup. Cover with a bit of milk or water. Then microwave on high for 1 minute. Remove and mash with a fork. Make sure there aren't any pits that evaded removal. If it's not completely mashable, return to the microwave for another 30 seconds. The dates transform into the most delicious, caramelly goo ever. The smell at this point is intoxicating.

Transfer the goo to a blender.

Measure out 3 cups of milk into the measuring cup you just used. Again, microwave until hot... maybe 3 minutes or so, depending on your microwave. Pour into the blender. Add the cocoa, xanthan gum (if using), and vanilla extract. Blend for 1 minute. Pour into mugs and allow to sit for 2 minutes.
