This is what I make when i have a sugar craving. We make these several times a week, usually late at night to enjoy while watching a good movie or an episode of star trek. :) Before you can make this you need to freeze ripe bananas. Because we use so much of these I try to buy over-ripe bananas in bulk from the produce manager. They will often give them to me at half off or some other deal. I peel and break the bananas in half (if your blender isn't very tough you'll need to break the bananas in bite size pieces) and stuff them in big zip-loc bags to freeze. The frozen bananas are what makes the shake so creamy. Don't substitute unfrozen bananas! In a few hours they'll be ready for your banana ice cream.
3 Frozen Bananas
1 cup vanilla Soy or Rice Milk
1/8 tsp Nutmeg
1/2 tsp Cinnamon
This isn't a science. I hardly ever measure anymore, I just grab a few frozen bananas, add enough milk to blend it and make the the consistency you like and add spices to taste. Blend until it's all smooth and enjoy.
