I'm suddenly wishing I had gotten the raw cashews instead of the roasted while at the store today.  From Anthropologie's blog...

WHAT YOU’LL NEED

1 cup raw cashews (soaked for 4 to 8 hours)
1/3 cup cocoa powder
1 tsp. vanilla extract1 tsp. cinnamon
2 tbs. agave nectar
1/2 tsp. sea salt
3 cups water

HOW TO MAKE IT…

Drain the cashews and rinse with cold water. Combine cashews and remaining ingredients in a blender (we used a Vitamix, but any high-speed model should do the trick). Start at a low speed, then crank up to high. Let the mixture blend for about five minutes, or until it reaches the desired toasty temperature and creamy consistency. Serve immediately in a mug or tumbler.

Makes three servings.
