01 - Line a mini muffin tin or a baking sheet with parchment paper and set aside.
02 - In a large mixing bowl, toss together the puffed quinoa, rolled oats, and shredded coconut until evenly distributed. Fold in any optional chopped nuts or dried fruit at this stage if using.
03 - Place the dark chocolate chips, peanut butter, coconut oil, and maple syrup in a medium heatproof bowl. Melt using a microwave in 30-second intervals, stirring between each, or set over a double boiler and stir until completely smooth and glossy.
04 - Pour the melted chocolate mixture over the dry ingredients. Stir thoroughly with a spatula until every piece is evenly coated and no dry pockets remain.
05 - Using a tablespoon or cookie scoop, portion rounded spoonfuls of the mixture into the prepared mini muffin tin cups or onto the lined baking sheet. Press each portion down gently but firmly to form compact, uniform bites. Sprinkle with flaky sea salt if desired.
06 - Refrigerate the bites for at least 1 hour, or until they are completely firm and hold their shape when handled.
07 - Carefully remove the bites from the muffin tin or peel them off the parchment paper. Transfer to an airtight container and store in the refrigerator for up to one week.
