Preheat oven to 425° F. Grease an 8-inch square baking pan.

Sift together flour, baking powder and salt; stir in cornmeal. In a medium sized bowl, beat the egg with a fork just enough to blend the yolk and white. Stir the milk and cooking oil into the egg. Add dry ingredients to milk mixture and stir to blend thoroughly; beat just until smooth. Pour into greased pan and bake for 25 minutes or until top is golden brown. Yield: 16 (2-inch) squares.
