In a medium saucepan, combine the light brown sugar, creamy peanut butter, honey, and unsalted butter over medium heat. Stir until the mixture is melted and smooth.
Remove the saucepan from heat and whisk in the espresso powder and cocoa powder until fully incorporated.
In a large mixing bowl, combine the quick oats, crispy rice cereal, and sliced almonds. Pour the warm peanut butter mixture over the dry ingredients.
Using a spatula, mix everything together until the oats and cereal are completely coated.
Fold in the mini semisweet chocolate chips until they are evenly distributed throughout the mixture.
Line a 9x9-inch baking dish with parchment paper, leaving some overhang for easy removal. Press the granola mixture firmly into the bottom of the dish in an even layer.
Refrigerate the bars for at least 1 hour or until they are firm enough to cut.
Once set, lift the bars out of the pan using the parchment paper and cut them into squares or rectangles.
