Start by lining a 9x9-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal.
In a medium mixing bowl, combine the light brown sugar, creamy peanut butter, honey, and unsalted butter. Microwave this mixture in 30-second intervals, stirring until melted and smooth (1-2 minutes).
In a separate large bowl, mix together the quick oats, crispy rice cereal, and Monster trail mix until evenly distributed.
Pour the melted mixture over the dry ingredients and fold until well-coated. The mixture should be sticky.
Gently fold in the semisweet chocolate chips, being careful not to overmix.
Transfer the mixture into the prepared pan and press firmly into an even layer.
Chill in the refrigerator for at least 1-2 hours to allow the bars to firm up.
Once set, lift the granola mixture out using the parchment overhang, place on a cutting board, and slice into bars.
