Line your 8x8 inch baking dish with parchment paper, leaving some overhang for easy removal.
In a large mixing bowl, combine the peanut butter and honey, stirring until smooth and fragrant—this mixture should feel sticky but manageable.
Add the rolled oats to the bowl and fold them into the peanut butter mixture until evenly coated and sticky.
Use a spatula or the back of a spoon to press the oat mixture firmly into the prepared dish, spreading it out evenly and pressing down to create a compact layer.
In a microwave-safe bowl, melt the chocolate chips and coconut oil in 30-second bursts, stirring well each time until the mixture is smooth, glossy, and completely melted.
Pour the melted chocolate over the pressed oat layer, using a spatula to spread it into an even, shiny top.
Place the dish in the refrigerator and chill for at least 2 hours, or until the chocolate is set and the bars are firm to the touch.
Once chilled, lift the bars out using the parchment overhang and place on a cutting board. Use a sharp knife to cut into 12 even squares, wiping the blade clean between cuts for neat edges.
Serve the bars immediately for a firm, crunchy bite, or store them in an airtight container in the fridge for up to a week. Enjoy these simple, no-bake treats anytime!
