Add rolled oats and vanilla protein powder to a large mixing bowl and stir to combine evenly
Add almond butter and honey, mixing until the ingredients begin forming a thick, cohesive mixture
Stir in peppermint extract and a pinch of salt, blending thoroughly to distribute flavor
Fold in mini dark chocolate chips gently so they remain evenly scattered throughout
If the mixture feels too dry, add milk one tablespoon at a time until it holds together when pressed
Scoop small portions using a tablespoon or cookie scoop
Roll each portion between your palms to form smooth, compact balls
Place the protein balls on a parchment-lined plate or tray
Refrigerate for at least 30 minutes until firm and set
Serve chilled for best texture and flavor
