Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
- In a large bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, baking powder, baking soda, salt, ground cinnamon, and ground nutmeg.
- In another bowl, combine pumpkin puree, sour cream, eggs, melted butter, and vanilla extract until smooth.
- Gently fold the wet mixture into the dry ingredients, being careful not to overmix.
- Pour the batter into the prepared pan and bake for 25–28 minutes, or until a toothpick comes out with moist crumbs.
- Let cool in the pan on a wire rack for about 30 minutes.
- Prepare the browned butter frosting by melting butter until golden brown and nutty.
- Mix in powdered sugar, milk, and vanilla extract until creamy and spreadable.
- Frost the cooled bars generously and let sit at room temperature for at least 10 minutes before cutting.

Notes
Use the spoon and level method for measuring flour, and watch the butter closely while browning.
