In a bowl, beat the eggs, oil, sugar and pumpkin until well blended. In a separate bowl, sift the flour, baking powder, baking soda, salt, cinnamon, ginger, cloves and nutmeg; gradually add to pumpkin mixture and mix well. Pour into a greased and floured 9x13-in. baking pan. Bake at 350° for 25-30 minutes or until set and when a toothpick is inserted near the center of the pan comes out clean. Cool completely.
