Remove the parbaked brownies from the oven. Evenly top the brownie layer with the pumpkin cream cheese layer.Add 1 tablespoon of hot water to the reserved ½ cup brownie batter. Mix well to combine. The batter should be thinned out enough to swirl easily, but not too thin that it becomes too runny. Drop 12 - 14 dollops of reserved and thinned out brownie batter onto the pumpkin cheesecake layer. Swirl the dollops of brownie batter into the cheesecake layer. Be careful not to overswirl. 1 - 2 tablespoons (15 - 30 ml) hot water
Return the pumpkin cheesecake topped brownies to the oven to finish baking. Bake the pumpkin brownies for another 30 - 35 minutes. Signs these pumpkin brownies are finished baking are a set, puffed up edges that have slightly pulled away from the edge of the pan and are lightly golden. A toothpick inserted into the center of the brownies should come away with a few moist crumbs. Remove the pumpkin cream cheese brownies to cool at room temperature for 1 hour. Cover and transfer the brownies to the fridge to chill and fully set for 2 -3 hours in the fridge. When it’s time to serve, use the parchment overhang to remove the brownies from the pan, slice and enjoy.
