Creating delicious Pumpkin Brownies is simple if you follow these easy steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease an 8×8-inch baking pan or line it with parchment paper for easy removal.
2. Mix Wet Ingredients: In a large bowl, combine the pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Mix until well combined.
3. Sift Dry Ingredients: In another bowl, sift together the all-purpose flour, cocoa powder, baking powder, baking soda, salt, and pumpkin pie spice, if using.
4. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.
5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips if desired for added richness.
6. Pour Batter: Pour the batter into the prepared baking pan, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
8. Cool the Brownies: Once baked, remove from the oven and place on a cooling rack. Allow them to cool in the pan for about 10-15 minutes before transferring them to the rack.
9. Cut into Squares: After cooling completely, cut into squares for serving.

These straightforward steps will guide you through the process of making Pumpkin Brownies that are bound to impress.
