Begin by placing a medium saucepan over low heat. Add the creamy peanut butter along with the honey (or maple syrup). Gently stir the mixture as it heats up, ensuring it melts completely and becomes smooth.
After the mixture has melted, remove the saucepan from the heat. Stir in the vanilla extract and a pinch of salt until well blended.
In a large mixing bowl, combine the rolled oats, chocolate chips, shredded coconut, and chia seeds, mixing them evenly to ensure distribution of all ingredients.
Slowly pour the warm peanut butter mixture over the dry ingredients in the bowl. Use a spatula or a sturdy spoon to carefully mix everything together until the dry ingredients are fully coated and the mixture is cohesive.
Prepare an 8x8-inch baking dish by lining it with parchment paper. Allow some excess parchment to hang over the edges for easy removal of the bars later.
Transfer the combined mixture into the prepared baking dish. With a spatula (or your hands if you prefer), press the mixture down firmly and evenly across the bottom of the dish to create a compact layer.
Place the baking dish into the refrigerator and let it chill for at least 2 hours. This will allow the bars to firm up sufficiently for cutting.
Once the mixture has set, carefully lift the bars out of the dish using the edges of the parchment paper. Place them on a cutting board and slice into squares or rectangles as preferred.
Store the bars in an airtight container, keeping them in the refrigerator where they will stay fresh for up to a week.
Notes
Present the bars beautifully on a rustic wooden board. For an appealing touch, dust them lightly with some shredded coconut on top and add a few chocolate chips as an elegant garnish.
