Ruffles Krispie Treats

Line an 8"-x-8” baking dish with parchment paper and spray with nonstick cooking spray. In a medium saucepan over medium-low heat, melt butter. When butter has melted, turn off the heat and stir in mini marshmallows until completely melted. (If the marshmallows aren’t melting, turn heat to low.) Remove pot from heat and add crushed chips, then stir with a plastic spatula until well combined. Immediately transfer mixture to prepared pan. Press down on mixture to make the bars more compact, then drizzle with melted chocolate. Let treats cool to room temperature, about 30 minutes, before slicing.
