In a large bowl, combine the rolled oats, almond flour, cocoa powder, and salt. Mix well until all the dry ingredients are fully combined.
In a separate bowl, stir together the maple syrup, peanut butter, and peppermint extract until smooth.
Pour the wet mixture into the dry ingredients and mix until everything is evenly coated and forms a sticky dough.
Line an 8x8-inch baking dish with parchment paper, leaving some overhang for easy removal.
Transfer the mixture into the lined dish and press it down firmly and evenly using a spatula or your hands.
In a microwave-safe bowl, combine the dark chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Pour the melted chocolate over the pressed mixture in the baking dish, spreading it evenly with a spatula.
Refrigerate the bars for at least 2 hours, or until set completely.
Once set, lift the bars out of the dish using the parchment paper and cut them into squares or bars.
For extra mint flavor, drizzle some melted dark chocolate on top or sprinkle some crushed mint leaves before serving.
