Heat oven to 425 degrees F. Lightly grease two 8-inch square baking pans. In large bowl, blend the dry ingredients.
In medium bowl, beat together milk, eggs, and oil. Make a well in dry ingredients, add liquid ingredients and stir together; blending well but not overstirring (mix may be slightly lumpy).
Divide batter equally between the two prepared baking pans. Bake for 20-25 minutes, until tops are nicely browned. Remove from oven and cool for at least 10 minutes before cutting into squares to serve.
