Blend the cottage cheese, powdered peanut butter, oat flour, cocoa powder, maple syrup, vanilla, and salt until thick and completely smooth.
Refrigerate the mixture for 30 minutes so it firms enough to shape.
Scoop the mixture into 12 portions and roll each portion into a smooth ball with lightly damp hands.
Melt the chocolate chips and coconut oil together in a heatproof bowl, stirring every 20 seconds until glossy.
Dip each truffle into the melted chocolate and place it on a parchment-lined plate.
Sprinkle the truffles with chopped peanuts before the coating sets.
Refrigerate for 20 minutes, then store chilled until ready to serve.
