Line a large loaf pan with parchment paper, allowing the paper to hang over the edges for easy removal later.

In a mixing bowl, combine peanut butter and honey. Stir together until smooth and creamy.

Add rolled oats to the peanut butter and honey mixture. Mix thoroughly until the oats are fully coated.

Transfer the oat mixture into the prepared loaf pan. Press the mixture evenly into the pan.

In a microwave-safe bowl, combine chocolate chips and coconut oil. Microwave in 30-second intervals until melted and smooth.

Pour the melted chocolate over the pressed oat mixture and spread into an even layer.

Sprinkle a pinch of flaky sea salt over the melted chocolate, if desired.

Refrigerate the assembled bars for 2-3 hours or until the chocolate has fully set.

Once set, lift the bars out of the pan using the overhanging parchment paper and slice into 12 equal bars.
