Instructions
Preparation Steps
Preheat oven to 350 F. Grease and line a 9 x 13 inch baking pan with parchment, leaving an overhang.
Whisk flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt in a large bowl.
In another bowl, whisk eggs, granulated sugar, brown sugar, oil, and vanilla until smooth. Whisk in pumpkin puree.
Add wet ingredients to dry and stir just until combined; do not overmix.
Spread batter evenly in the pan. Bake 22 to 28 minutes, until a toothpick comes out mostly clean from the center.
Cool completely in the pan on a rack, about 45 minutes, before frosting.
Make the frosting: Beat cream cheese and butter until creamy. Add powdered sugar, cinnamon, and vanilla; beat until fluffy. Add milk as needed for a smooth, spreadable consistency.
Spread frosting over cooled bars. Slice into 16 squares and serve. Store covered in the refrigerator for up to 5 days.
Notes
For extra warmth, dust the frosted bars lightly with cinnamon or pumpkin pie spice before slicing. Bars taste even better the next day.
