How to Make My Grandma's Pumpkin Bars

  1. Preheat oven to 350°F (175°C). Grease and flour a 15x10 inch jelly roll pan.
  2. In a large bowl, cream together the sugar and oil using an electric mixer until light and fluffy.
  3. Beat in the eggs one at a time, then stir in the pumpkin puree and vanilla extract.
  4. In a separate bowl, whisk together the flour, baking soda, baking powder, cinnamon, ginger, cloves, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
  6. Pour batter into the prepared pan and spread evenly.
  7. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs.
  8. Let the bars cool completely in the pan before frosting.
  9. While the bars are cooling, prepare the frosting. Beat together the butter, powdered sugar, and pumpkin pie spice until smooth and creamy. Add milk as needed to reach desired consistency.

  11. Cut into squares and enjoy! Optional: Decorate with candy corn for Halloween.
