Preheat oven to 350°F (175°C).

In a bowl, combine graham cracker crumbs, melted butter, and sugar.

Press the mixture firmly into the bottom of a 9×13-inch baking dish.

Bake for 8–10 minutes, then let cool slightly.

Pour sweetened condensed milk evenly over the crust.

Drizzle caramel sauce over the condensed milk.

Sprinkle chopped Butterfinger candy bars evenly on top.

Melt the chocolate chips and drizzle over the top, or simply sprinkle chocolate chips on top for a layered effect.

Refrigerate for 2–3 hours to set.

Cut into bars and enjoy that gooey, crunchy, caramel-chocolate goodness!
