In a large bowl, combine the first seven ingredients. In another bowl, combine the eggs, pumpkin and oil; stir into dry ingredients. Spread into a greased 15x10x1-in. baking pan. Bake at 350° for 18-22 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack.
For frosting, in a large bowl, beat the butter, cream cheese and vanilla until smooth. Gradually add confectioners’ sugar; mix well. Spread over top. Cut into 30 bars; top each bar with a pumpkin candy.
