In a food processor, combine soaked cashews, shredded coconut, maple syrup, protein powder, chia seeds, vanilla extract, and sea salt. Pulse until well blended.
Stir in the nut butter by hand or with a spatula until the mixture is thick and sticky enough to hold shape.
Using a small cookie scoop or spoon, roll the mixture into 24 bite-sized balls.
Place the bites on a parchment-lined tray and chill in the freezer for 1 hour to set.
Store in an airtight container in the refrigerator or freezer for up to 2 weeks.
