Ingredients

  • 1 cup unsalted butter
  • 2 ¼ cups all-purpose flour
  • 1 teaspoon baking soda
  • ¾ teaspoon kosher salt
  • 1 ½ teaspoons ground cinnamon
  • ½ teaspoon ground ginger
  • ¼ teaspoon ground nutmeg
  • ⅛ teaspoon ground cloves
  • ¾ cup packed light brown sugar
  • ¾ cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 cup pumpkin puree
  • 2 teaspoons pure vanilla extract
  • 1 ¾ cups semisweet chocolate chunks (about a 10 oz bag)
  • Sea salt flakes for sprinkling on top (optional)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan with nonstick spray and set aside.
  2. In a medium saucepan, melt the butter over medium heat. Increase heat to medium-high and stir until golden bits form and a nutty aroma develops, about 3–5 minutes. Pour into a heat-safe bowl and cool slightly.
  3. In a separate bowl, whisk together flour, baking soda, salt, cinnamon, ginger, nutmeg, and cloves.
  4. In a large mixing bowl, combine browned butter, brown sugar, and granulated sugar. Stir until smooth.
  5. Add the egg, egg yolk, pumpkin puree, and vanilla extract. Mix until fully combined.
  6. Gently stir in the dry ingredients until just combined—do not overmix.
  7. Fold in chocolate chunks evenly.
  8. Spread batter evenly in the prepared pan and sprinkle with sea salt flakes if desired.
  9. Bake for 28–35 minutes or until golden brown around the edges and the center is set.
  10. Let bars cool completely before cutting into squares.

Notes

  • Use a light-colored pan to avoid burning the butter while browning.
  • Do not overmix the batter to maintain soft, chewy texture.
  • Bars taste even better the next day as flavors develop.
  • Use chocolate chips if you don’t have chunks.
  • Top with cream cheese frosting for an extra indulgent treat.
