Ingredients

  • 8 tablespoons (1 stick) unsalted butter, melted and cooled
  • 1 1/4 cups sugar
  • 3 large eggs
  • 1 cup canned pumpkin puree
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder

  • 1 3/4 cups all-purpose flour
  • 1/3 cup milk
  • 1 cup miniature chocolate chips

Method

  • Preheat oven to 350°F. Mist an 8-inch square baking pan with cooking spray; line with parchment.
  • Whisk together butter, sugar, eggs, pumpkin puree and vanilla in a large mixing bowl. Stir in baking soda, baking powder, pumpkin pie spice and salt. Stir in 1/2 of flour, then milk, then remaining flour, stirring until just combined (do not overmix). Fold in chocolate chips and nuts.
  • Scrape batter into pan and smooth top with a rubber spatula. Bake until firm to the touch and a toothpick inserted in center comes out clean, 55 to 60 minutes.
