Peel 2 bananas, about 1 cup. Put them in a container broken into pieces and freeze.

If you want you may freeze the 1/2 to 1 cup of plain yogurt. The frozen bananas does make unfrozen yogurt turn into a soft freeze treat.

Put bananas and yogurt into food processor or blender. Add 1 teaspoon vanilla and blend just until blended.

You may eat now - soft cone, or freeze to hard cone. Also freeze leftovers. Remove from freezer for several minutes before eating. Serves 2.
