In a medium saucepan, combine the creamy peanut butter and honey (or maple syrup) over low heat. Stir until melted and smooth.
Remove from heat and add the vanilla extract and salt, mixing thoroughly.
In a large bowl, combine the rolled oats and almond flour. Pour the peanut butter mixture over the dry ingredients and stir until everything is well combined.
If using, fold in the dark chocolate chips and chopped nuts for added texture.
Line a square baking dish (8x8 inches) with parchment paper, leaving some overhang for easy removal.
Pour the mixture into the lined dish and press it down firmly with a spatula or your hands, ensuring it’s evenly distributed and compacted.
Refrigerate for at least 1 hour to set. Once firm, remove from the dish using the parchment overhang and cut into bars.
Store any leftover bars in an airtight container in the refrigerator for up to a week.
