Ingredients

  • 3/4 cup margarine
  • 2 cups sugar
  • 1 (16 oz.) can pumpkin
  • 4 eggs
  • 2 cups flour
  • 2 teaspoons baking powder
  • 1 teaspoon cinnamon
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/4 teaspoon nutmeg
  • Vanilla frosting

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Cream margarine and sugar until light and fluffy.
  3. Blend in pumpkin and eggs.
  4. Combine dry ingredients: flour, baking powder, cinnamon, baking soda, salt, and nutmeg.
  5. Add dry ingredients to the pumpkin mixture and mix well.
  6. Spread the batter into a greased and floured 15 1/2 x 10 1/2-inch jelly roll pan.
  7. Bake for 30 to 35 minutes until a toothpick inserted in the center comes out clean.
  8. Allow the bars to cool completely, then frost with vanilla frosting.

Tips & Substitutions

For a richer flavor, consider substituting half of the margarine with unsalted butter. If you don't have nutmeg, you can use allspice as a substitute. Make sure to measure the flour accurately by spooning it into the measuring cup and leveling it off to avoid dense bars. If you prefer a healthier option, replace some of the sugar with applesauce.

Serving Suggestions

These Colonial Pumpkin Bars are delightful on their own but can be served with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent treat. They pair beautifully with a cup of spiced chai or coffee. For a festive touch, sprinkle chopped pecans or walnuts on top of the frosting, or enjoy them alongside a slice of Strawberry Chocolate Chip Cheesecake.

Storage & Reheating

Store leftover pumpkin bars in an airtight container in the refrigerator for up to one week. To reheat, place a bar in the microwave for 15-20 seconds or until warm. These bars can also be frozen for up to three months; just wrap them tightly in plastic wrap and then foil before freezing.
