• Preheat oven to 350 degrees.
• Line a large baking sheet pan with parchment paper. Make sure the paper goes slightly over the edges of the pan.
• In a large bowl, combine graham cracker crumbs, condensed milk, and chocolate chips. Mix together with a large spoon.
• Pour onto the parchment lined pan. With wet hands press mixture down into the pan.
• Bake for 20-25 minutes or until the edges are starting to turn golden brown. For chewier bars, cook for about 20-22 minutes. For crunchier bars, cook until the top turns golden brown, 23-25 minutes.
• Let cool for at least 15-20 minutes before cutting. To speed up the process, place the bars in the refrigerator.
• Use a sharp knife to cut the bars into neat squares or rectangles.
• Sprinkle powdered sugar on top.
• Serve and enjoy!
