Heat oven to 350°F. Place cones upright in medium muffin cups, 2 1/2x1 1/4 inches, or rectangular pan, 13x9x2 inches. Mix flour, sugar, malted milk powder, cocoa, baking soda and salt in medium bowl. Beat oil, vinegar and vanilla with wire whisk. Stir oil mixture and water into flour mixture about 1 minute or until well mixed. Pour batter into cones, filling each to within about 1 inch of top.
