1 cup fresh cranberries, quartered
8 tablespoons sugar, divided
1-3/4 cups all-purpose flour
2-1/2 teaspoons baking powder
1/4 teaspoon salt
1 large egg
3/4 cup milk
1/3 cup vegetable oil
1 teaspoon grated lemon zest, optional
Sprinkle cranberries with 2 tablespoons sugar; set aside. Sift remaining sugar, flour, baking powder and salt into large bowl.
In another bowl, beat egg, milk and oil. Make a hole in center of dry ingredients; pour in liquid ingredients. Stir just until moistened. Add berries and, if desired, lemon zest. Fill 12 greased standard or 6 greased jumbo muffin cups. Sprinkle with cinnamon sugar.
Bake at 400° for 18 minutes for standard-size muffins or for 22 minutes for jumbo muffins.
