Preheat oven to 375 degrees. In a large bowl, mix all ingredients together (except for the topping), then press into a 13 by 9-inch lightly greased, preferably glass baking dish. In a small bowl, mix together topping ingredients and set aside. Place baking dish in oven and bake for 35 minutes. Remove and cover with topping mixture. Return to oven for another 20-25 minutes.
Remove from oven and let stand for about 15 minutes. Cut into squares to serve. 12-16 servings.
