Preheat oven to 400°F.

Grease an 8- or 9-inch square pan or a 12 cup muffin pan.

Combine dry ingredients.

Stir in egg, oil, and milk, mixing just until dry ingredients are moistened.

Pour batter into prepared pan. Bake 20 to 25 minutes or until light golden brown and wooden pick inserted in center comes out clean.

To make muffins, evenly distribute batter into twelve greased or paper-lined medium muffin cups, or six large muffin cups. Bake 15 to 20 minutes or until golden brown.
