Ingredients

Scale

For the Pumpkin Bars

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1 cup canned pumpkin puree
  • 1/2 cup sour cream
  • 2 large eggs
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract

For the Brown-Butter Frosting

  • 1/2 cup unsalted butter
  • 2 cups powdered sugar
  • 2 tablespoons milk
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan to prevent sticking.
  2. Mix Dry Ingredients: In a large bowl, whisk together all-purpose flour, granulated sugar, baking powder, baking soda, salt, cinnamon, and nutmeg to evenly distribute the leavening agents and spices.
  3. Mix Wet Ingredients: In a separate bowl, combine the canned pumpkin puree, sour cream, eggs, melted butter, and vanilla extract. Whisk until the mixture is smooth and homogeneous.
  4. Combine Wet and Dry: Pour the wet ingredients into the dry ingredients bowl and gently stir just until blended to avoid overmixing which can toughen the bars.
  5. Bake the Bars: Pour the batter into the prepared pan. Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted in the center comes out clean.
  6. Prepare Brown Butter Frosting: While the bars bake, melt the butter in a saucepan over medium heat. Continue to cook until the butter turns a golden brown color and develops a nutty aroma. Remove from heat and allow it to cool slightly.
  7. Mix Frosting Ingredients: Whisk the browned butter with powdered sugar, milk, and vanilla extract until the frosting is smooth and creamy.
  8. Frost and Serve: Once the pumpkin bars have cooled completely, spread the brown-butter frosting evenly over the surface. Cut into squares and serve.

Notes

  • Be careful when browning butter—watch closely to avoid burning.
  • Allow pumpkin bars to cool fully before frosting to prevent melting or sliding.
  • You can substitute Greek yogurt for sour cream for a tangy alternative.
  • For extra flavor, add chopped nuts or chocolate chips to the batter.
  • Store bars in an airtight container at room temperature for up to 3 days or in the refrigerator up to a week.
