Preheat your oven to 350°F (175°C). Grease a 13x9-inch baking pan with softened butter and line with aluminum foil.

In a medium mixing bowl, combine graham cracker crumbs, melted salted butter, and granulated sugar. Press firmly into the bottom of the prepared baking pan.

Bake the crust for 8 minutes until edges are lightly golden.

Sprinkle half the semi-sweet chocolate chips evenly over the crust, followed by pecans and coconut. Top with remaining chocolate chips.

Pour sweetened condensed milk over the toppings, ensuring even distribution.

Return to oven and bake for an additional 25–30 minutes until edges are bubbly and golden brown.

Cool in the pan for about 10 minutes, then lift out and cool completely on a wire rack before cutting into squares.
