Preparation Steps

• Preheat oven to 350°F. Line a 9×9-inch baking dish with parchment paper. Set aside.
• Whisk melted butter and brown sugar in a large bowl until fully incorporated.
• Add the pumpkin and vanilla. Whisk to combine.
• In a separate, medium-sized bowl, whisk together the flour, cornstarch, pumpkin spice, baking powder, salt, and nutmeg.
• Gradually stir the flour mixture into the pumpkin mixture until completely combined.
• Spread the batter into the bottom of the lined baking dish. (The batter is thick.)
• In a small bowl, whisk together the granulated sugar and cinnamon.
• Evenly sprinkle the mixture over the batter.
• Bake for 35-38 minutes, or until the edges just begin to turn golden brown and the center is no longer jiggly. Check at 30 minutes and insert a toothpick to ensure it comes out with crumbs only.
• Allow the bars to cool slightly before cutting and serving.
