Prepare Filling:
Place cream cheese and brown sugar in stand/hand mixer bowl (no need to clean out after preparing topping) and mix until smooth.
Add pumpkin and spices to cream cheese and mix well.
Slowly mix heavy cream into pumpkin mixture. Increase speed and mix for a couple minutes or until mixture has some body. (You don't want it to be runny.) Set aside.
Assemble Pies:
Melt chocolate in microwave.
Transfer melted chocolate to a small ziplock or pastry bag. Set aside.
Place 1 teaspoon toffee bits in the bottom of each graham cracker crust.
Top toffee with pumpkin filling.
Snip a small corner off the ziplock bag. Drizzle chocolate over the pumpkin filling.
