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
- 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.
 - 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.
 - 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.
 - Combine Wet and Dry: Gradually stir the dry ingredient mixture into the pumpkin mixture until fully blended, forming your base batter.
 - 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.
 - 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.
 - 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.
 - 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.
