Pumpkin Bars

"These Pumpkin Bars are moist and flavorful, with pumpkin puree and hints of cinnamon, ginger, allspice, and cloves, topped with a four-ingredient cream cheese frosting. Line the baking pan with parchment paper or spray with nonstick baking spray. Bake just until set. You can use the toothpick test. Insert a toothpick in the center of the bars. If it comes out clean or with a few moist crumbs, but no wet batter, they’re ready. Soften both the cream cheese and butter before you start to ensure a smooth, creamy, lump-free texture. Take the time to beat the cream cheese until it is lump-free. This can take a couple of minutes, or up to 5 minutes when you add the butter."
