Fudgy, gooey, and flour-less vegan pumpkin brownies marbled with a pumpkin spice filling. A healthy and decadent autumn treat that's simple (prep time is just 10 minutes!), and requires no special equipment.
Preheat oven to 350 degrees F. Coat a 8″x8″ baking dish with non-stick cooking spray and line with parchment paper.
In a large bowl, whisk together the cocoa powder, brown sugar, baking soda, salt, and pumpkin pie spice.
