Line an 8x8-inch pan with parchment paper and combine all dry ingredients in a large bowl so everything distributes evenly before mixing.
Warm the peanut butter, honey, and maple syrup over low heat until smooth and glossy, then stir in vanilla extract for extra flavor and aroma.
Pour the warm mixture over the dry ingredients and stir thoroughly until all oats and seeds are fully coated for proper binding.
Let the mixture cool slightly before adding chocolate chips so they keep their shape instead of melting completely into the mixture.
Press the mixture firmly into the prepared pan using the back of a measuring cup to create compact bars that slice neatly later.
Refrigerate for at least 1 hour until firm, then slice into bars or snack bites using a sharp knife for clean edges.
