Place the softened cream cheese in a large mixing bowl and beat until smooth and creamy.
Add the pumpkin puree, sweetened condensed milk, alcohol-free vanilla, and 1 teaspoon cinnamon.
Beat until the pumpkin cheesecake mixture is completely smooth and evenly combined.
In a separate mixing bowl, combine the instant vanilla pudding mix, maple syrup, whipped topping, and remaining 1/2 teaspoon cinnamon.
Gently mix until smooth and evenly incorporated.
Arrange 6 cinnamon graham crackers across the bottom of an 11-by-7-inch baking dish, breaking crackers as necessary to cover the bottom.
Spread half of the pumpkin cheesecake mixture evenly over the graham crackers.
Arrange the remaining graham crackers over the cheesecake layer.
Drizzle approximately 1/3 cup caramel sundae sauce evenly over the graham crackers.
Carefully spread the remaining pumpkin cheesecake mixture over the caramel layer.
Spread the whipped topping and pudding mixture evenly across the cheesecake layer.
Drizzle the remaining 1/3 cup caramel sauce over the top of the No Bake Pumpkin Cheesecake Lasagna.
Sprinkle evenly with 1/4 cup toffee bits.
Cover the baking dish and freeze for at least 4 hours, or until firm enough to slice.
Before serving, allow the dessert to soften slightly if it is completely frozen.
Cut into squares and garnish with whipped cream and additional toffee bits if desired.
