Preheat oven to 350°F. Line a 9x13 baking pan with parchment paper that is large enough to have an overhang that you can use to pull the bars out the pan once they’re baked.
In a large bowl, whisk the flour, cinnamon, ginger, nutmeg, cloves, and salt until evenly combined. In a separate large bowl, whisk together butter, sugar, egg, vanilla, and pumpkin until smooth and completely combined. Add the dry ingredients to the wet ones stirring until just combined. Fold in the chocolate chips.
Pour the batter into the pan and bake the bars for 35 minutes or until a toothpick comes out clean. Cool the bars completely in the pan before slicing and serving.
