Step 1

Preheat oven to 350°F (177°C). Line a 9x13-inch pan with aluminum foil or parchment paper, leaving some overhang for easy removal, and set aside.

Step 2

Add the graham cracker crumbs and melted butter to a mixing bowl and stir until all of the crumbs are moistened. Scoop into the prepared pan and firmly press it down into one even layer.

Step 3

Spray the sides of the foil or parchment paper with nonstick cooking spray (so the topping doesn't stick to the edges). Sprinkle the chocolate chips, peanut butter chips, shredded coconut, and chopped pecans on top of the graham cracker layer one at a time. Pour the can of sweetened condensed milk over the top.

Step 4

Bake at 350°F (177°C) for 25-30 minutes or until the edges begin to brown and the top is lightly browned. Remove from the oven and cool completely on a wire rack.

Step 5

Once the bars have cooled completely in the pan, remove them using the overhang from the foil or parchment paper, slice into bars, and enjoy!
