Pumpkin Bars Brown Sugar Frosting

Featured in: Sweet Bakes

These pumpkin bars offer a moist texture infused with warm spices like cinnamon, nutmeg, and cloves. The batter combines pumpkin puree, oil, sugar, and eggs, with optional nuts folded in for added crunch. Baked in a 9x13 inch pan, the bars are cooled before applying a luscious brown sugar cream cheese frosting. The frosting blends butter, cream cheese, powdered sugar, and brown sugar, finished with vanilla extract and milk for spreadability. Perfect for fall gatherings, these bars balance spice, sweetness, and creaminess in every bite.
