In a bowl, mix graham cracker crumbs and melted butter until evenly combined.
Divide the mixture into serving cups and press firmly to form the crust layer.
In another bowl, beat softened cream cheese until smooth and lump-free.
Add powdered sugar and vanilla extract, then mix until creamy and fully combined.
In a separate bowl, whip cold heavy cream until soft peaks form.
Gently fold the whipped cream into the cream cheese mixture until light and smooth.
Stir in half of the toffee bits evenly into the filling.
Spoon or pipe the cheesecake filling over the crust in each cup.
Smooth the tops and drizzle caramel sauce over each cup.
Sprinkle remaining toffee bits on top for garnish.
Refrigerate for at least 2 hours until fully set before serving.
