1. Blend the base: In a food processor, combine the dates, nuts, collagen powder, oats, cocoa powder, peppermint extract, and sea salt. Process until the mixture becomes thick and sticky, holding together when pressed.
2. Add chocolate chips: Transfer the mixture to a bowl and fold in the mini chocolate chips until evenly distributed.
3. Form the bites: Roll about one tablespoon of dough into balls and place them on a parchment-lined baking sheet.
4. Chill and enjoy: Refrigerate the bites for at least 30 minutes to firm up. Enjoy them straight from the fridge or let them soften slightly at room temperature for a fudgier texture.
