1 2/3 cups granulated sugar
1 cup vegetable oil (can substitute 1/2 cup applesauce for 1/2 cup oil)
15-ounce can pumpkin
2 cups sifted all-purpose flour
2 teaspoons baking powder
2 teaspoons ground cinnamon
1 teaspoon salt
1 teaspoon baking soda
8-ounce package cream cheese, softened
1/2 cup butter or margarine, softened
2 cups sifted confectioners' sugar
1 teaspoon vanilla extract
Preheat the oven to 350 degrees F.
Mix the eggs, sugar, oil and pumpkin together until light and fluffy. Stir together the flour, baking powder, cinnamon, salt and baking soda. Add the dry ingredients to the pumpkin mixture and mix at low speed until thoroughly combined and the batter is smooth. Spread the batter into a greased 13x9 baking pan. Bake for 30 minutes. Let cool completely before frosting.
To make the icing, combine the cream cheese and butter in a medium bowl with an electric mixer until smooth. Add the sugar and mix at low speed until combined. Stir in the vanilla and mix again. Spread on cooled pumpkin bars.
