Ingredients:

For the bars:
1 cup butter; room temperature
1/2 cup brown sugar
1 1/2 cup granulated sugar
4 eggs
2 tsp vanilla
1 cup pumpkin
6 cups flour
1 tsp salt
1/2 tsp baking soda
4 teaspoons pumpkin pie spice
1/4 teaspoon cardamom

For the Buttercream:
3/4 cup butter; room temperature
3/4 cup shortening
1 1/2 tsp vanilla
pinch of salt
3/4 teaspoon ground cinnamon
6 cups powdered sugar
7 - 8 Tbsp milk
food coloring (if desired)

Directions:
For the bars:
Cream butter and sugar until fluffy. Add the eggs, one at a time, mixing after each egg. Add vanilla and mix well. In a separate bowl combine flour, salt, baking soda, pumpkin pie spice, cardamom, and cloves. Stir the flour mixture with a whisk to combine. Add half of the flour mixture to the wet mixture and mix just until combined. Then add the pumpkin puree, followed by the remaining flour mixture. Stir until just combined. Spread on a greased 13x18 inch baking pan.

Bake at 375 degrees for 10-20 min, until light golden brown or until a toothpick comes out clean. Cool completely and frost.

For the frosting:
Combine butter and shortening until smooth and creamy. Add vanilla and salt. Add powdered sugar in 1-2 cup increments until combined, then add milk & mix until smooth and spreading consistency. Spread over cooled cookie.

Tip: To make your own Pumpkin Pie Spice, combine 1 teaspoon cinnamon, 1/2 teaspoon ginger, 1/4 teaspoon allspice, and 1/8 teaspoon nutmeg. Makes 2 teaspoons.
