Raisin Pumpkin Bars Recipe

In a large bowl, beat sugar and oil. Add eggs, one at a time, beating well after each addition. Add pumpkin; mix well. Combine the flour, baking powder, baking soda and spices; gradually add to the pumpkin mixture. Stir in walnuts and chocolate-covered raisins. Pour into a greased 15-in. x 10-in. x 1-in. baking pan. Bake at 350° for 25-30 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack. For frosting, in a large bowl, cream the butter, cream cheese and confectioners' sugar. Add milk and orange extract; beat until smooth. Frost bars. Decorate with sprinkles if desired. Cut into bars. Store in the refrigerator. Yield: 4 dozen.
