1/2 cup nonfat dry milk
1/3 cup mashed ripe banana
1/4 cup vegetable oil
1 egg
1 beef bouillon cube, dissolved in 1/2 cup hot water

Mix all ingredients until well blended. Knead for 2 minutes on a floured surface. Roll to 1/4" thickness. Use a 2 1/2" bone-shaped cookie cutter (or any one you prefer). Bake for 30 minutes in a 300-degree F oven on ungreased cookie sheets.
