Apple Nut Bars

Preheat the oven to 350 degrees. In a large bowl, mix together the flour, sugar, salt, and baking powder. Add the remaining ingredients and mix well. Place the batter in a greased 9" x 13" baking pan. Bake for 40 to 50 minutes or until the edges are golden. Remove from oven and cut into bars while still warm, not hot. Note: Before serving, you might want to roll the bars in confectioner's sugar or spread with a cream cheese frosting. Maybe serve them with whipped topping as a dip or serve plain as a great snack cooki
