In a bowl, mix graham cracker crumbs, melted butter, and granulated sugar until combined.
Press into a greased 8x8-inch pan to form the crust. Chill in the refrigerator for 15 minutes.
In another bowl, beat softened cream cheese until smooth. Mix in caramel sauce, powdered sugar, and vanilla extract until creamy.
Gently fold whipped cream into the cream cheese mixture until smooth and fluffy.
Spread the cheesecake filling evenly over the crust. Sprinkle with crushed Butterfinger and drizzle with caramel sauce.
Refrigerate for at least 4 hours (or overnight) until set.
Slice into bars and top with whipped cream before serving, if desired.
