Preheat the oven to 350° Fahrenheit.
Liberally spray the 8x8” baking dish with cooking spray. Place parchment paper over the bottom and sides of the pan, leaving a little overhanging so that you can pull it out easily. Spray the parchment paper with cooking spray.
Melt the butter in a microwave safe bowl with the chocolate at 50% power for 1 minute. Stir then continue to microwave at 50% in 30 second increments until fully melted and smooth, about 5 minutes.
Stir in the vanilla, instant coffee and salt.
Mix in the granulated sugar. Add the eggs and stir until fully combined. Sir in flour and cocoa powder until it is just mixed.
Spoon the brownie batter into the bottom of the prepared pan and smooth it out so it is even. Set aside for now.
Beat the cream cheese in a large bowl on medium speed until smooth, about 1-2 minutes. Add the egg, pumpkin puree, sugar, flour, pumpkin pie spice, vanilla, and salt. Continue beating on medium speed until fully combined, about 1 minute.
Spoon the cheesecake batter over the brownie batter and smooth it out so it is even. Be careful, as you want the cheesecake batter to sit on top of the brownie batter. Don’t mix the two.
Bake for 35 to 40 minutes. You want the edges of the cheesecake to be browned slightly, and the cheesecake will appear dry. Remove from the oven and cool completely to room temperature before slicing and serving.
