In a medium mixing bowl, combine the rolled oats, ground flaxseed, chopped nuts, chia seeds, and salt. Mix well until combined.
In a separate bowl, mix the peanut butter, honey (or maple syrup), and vanilla extract until smooth and creamy.
Pour the peanut butter mixture into the dry ingredients and stir until everything is well combined.
Gently fold in the dark chocolate chips, ensuring they are evenly distributed throughout the mixture.
Line a 9x9 inch baking pan with parchment paper, allowing some overhang for easy removal. Transfer the energy bar mixture into the pan and press down firmly with a spatula or your hands to create an even layer.
Refrigerate the pan for at least 1-2 hours, or until the mixture is set.
Once firm, lift the mixture out of the pan using the parchment paper and cut it into bars or squares of your desired size.
Store the bars in an airtight container in the refrigerator for up to two weeks.
Notes
Arrange the energy bars on a platter and garnish with a sprinkle of sea salt or a drizzle of melted chocolate for an extra touch of flair.
