Pumpkin Spice Bars

FOR BARS: In a large mixing bowl stir together the flour, brown sugar, granulated sugar, baking powder, baking soda, crystallized or ground ginger, cinnamon, and salt. In another mixing bowl beat the eggs slightly. Stir in the pumpkin, raisins, and oil. Stir pumpkin mixture into flour mixture.

Spread batter into an ungreased 15x10x1-inch baking pan. Bake in a preheated 350-degree oven for 15 to 20 minutes, or till a wooden toothpick inserted near the center comes out clean. Cool in pan on a rack.

FOR TOPPING: In a small, heavy-duty plastic bag combine baking bar and shortening. Close bag just above ingredients, then set sealed bag in a bowl of warm water till contents are melted. Snip 1/4 inch from one corner of bag. Squeeze topping from bag over bars in a crisscross design. Cut bars before topping is completely set.
