  • Total Time: 50 minutes
  • Yield: 9 brownies

Ingredients

Dry Ingredients

  • 1 cup all-purpose flour
  • 2 teaspoons pumpkin pie spice
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Wet Ingredients

  • 1/4 cup canola oil
  • 1 cup granulated sugar
  • 2 eggs
  • 1 (15 ounce) can pure pumpkin
  • 1 teaspoon vanilla extract

Additional Ingredients

  • 1/4 cup unsweetened cocoa powder
  • 1/2 cup semi-sweet chocolate chips

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Spray an 8×8-inch baking dish with cooking spray to prevent sticking and set it aside.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, pumpkin pie spice, baking powder, baking soda, and salt to ensure they are evenly combined.
  3. Mix Wet Ingredients: In a separate bowl, whisk together the canola oil, granulated sugar, eggs, pure pumpkin, and vanilla extract until smooth and well incorporated.
  4. Combine Wet and Dry: Gradually stir the dry ingredient mixture into the pumpkin mixture until fully blended, forming your base batter.
  5. Separate and Make Chocolate Batter: Remove half of the batter into a separate bowl. Into this portion, stir the unsweetened cocoa powder thoroughly, then fold in the semi-sweet chocolate chips to create the chocolate swirl batter.
  6. Layer and Swirl: Alternate dolloping spoonfuls of the pumpkin batter and the chocolate batter into the prepared baking dish in a checkered pattern. Using a knife or the end of a wooden spoon, gently swirl the batters to create a marbled effect without fully mixing.
  7. Bake: Place the pan in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
  8. Cool and Serve: Allow the brownies to cool completely in the pan before cutting into 9 squares for serving.

Notes

  • Make sure not to over-swirl the batters to keep distinct chocolate and pumpkin swirls visible.
  • Use a sharp knife to cut when cooled for cleaner edges.
  • Store leftover brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
  • For a dairy-free option, use dairy-free chocolate chips.
  • These brownies freeze well; wrap tightly and freeze up to 3 months.
