Place the cottage cheese and peanut butter into a blender or food processor.
Blend until smooth and creamy, scraping down the sides if necessary.
(Optional) Add 2–3 tablespoons sweetener if you prefer a sweeter filling. Pulse to combine.
Scoop out the mixture and roll it into 5–8 evenly sized balls.
Place the balls on a parchment-lined plate or tray and freeze them for about 1 hour.
Melt the chocolate chips in a microwave-safe bowl in 30-second increments, stirring between bursts, until smooth.
Carefully dip or roll each frozen ball in the melted chocolate, then return it to the parchment-lined tray.
Chill again until the chocolate sets (about 10 minutes in the freezer or 20 minutes in the fridge).
Enjoy immediately or store in the fridge or freezer for future snacking.
