Preheat the oven to 350 degrees F. Grease a 9 x 9 for thick brownies.
In a medium mixing bowl whisk together the flour, baking powder, salt, and cocoa until well combined, set aside.
In a large mixing bowl whisk together the sugar, butter, eggs, and vanilla until well combined.
Stir together the dry ingredients and the wet ingredients together and set aside.
In a medium mixing bowl stir together the pumpkin, eggs, vanilla, and pumpkin pie spice.
Spread half of the brownie mix to 3/4 of the brownie batter evenly into your greased baking dish.
Top the brownie batter with the pumpkin mixture.
Layer the last of the brownie batter on the top and lightly swirl a butter knife through the layers so you can see the pumpkin pie mix in the brownie batter.
Bake for 25 – 28 minutes or until a tooth pick comes out clean from the middle of the brownies.
