In a large mixing bowl, combine the creamy peanut butter and honey (or maple syrup). Use a spatula or a whisk to blend them together until the mixture is smooth and well combined.
Next, incorporate the rolled oats, protein powder, chia seeds, vanilla extract, and a pinch of sea salt into the bowl. Stir the mixture thoroughly until all the ingredients are evenly distributed, resulting in a thick, dough-like consistency.
Prepare a square baking dish, approximately 8x8 inches. Line it with parchment paper, ensuring there is an overhang on the edges. This will help you lift the bars out easily later.
Transfer the peanut butter mixture into the prepared dish. Use a spatula to spread it evenly, pressing down firmly to create a smooth, level surface. This step is crucial for achieving the right texture.
Optional: To add a chocolatey finish, place the dark chocolate chips in a microwave-safe bowl. Heat them in 30-second intervals, stirring in between, until melted and smooth. Drizzle the melted chocolate over the pressed mixture or spread it evenly using a spatula for a delightful layer of chocolate.
Place the dish in the refrigerator and chill for at least 1 to 2 hours until the mixture hardens. After refrigeration, carefully lift the bars out of the dish using the parchment paper overhang and transfer them to a cutting board.
Cut the chilled mixture into squares or rectangles based on your desired serving size. Store any leftover bars in an airtight container in the refrigerator for up to a week or freeze them for future enjoyment.
Notes
Serve these bars individually wrapped in parchment or placed on a platter. You can also sprinkle some extra chia seeds or a dusting of cocoa powder on top for a decorative touch.
