This is one of my new favorite bedtime treats. It tastes like you're indulging in an ice cream shake, but except for the little bit of sugar, it's good for you. If you split it with someone, it's only 147 calories each.
2 frozen banana halves *
1 cup skim milk
1 Tablespoon sugar
1/4 teaspoon vanilla
Put all ingredients in blender and pulse until well-blended.
* I peel and freeze bananas in a ziplock freezer bag before they start to get overripe. I usually cut them in half first. Don't wait until they get soft to freeze them, or they'll only be good for banana bread.
