In a medium mixing bowl, combine the Greek yogurt, natural peanut butter, vanilla whey protein powder, and honey until the mixture is smooth and homogeneous.
Line a baking sheet or flat tray with parchment paper to prevent sticking.
Using a tablespoon or small cookie scoop, portion the mixture into 12 equal dollops on the prepared parchment paper.
Transfer the tray to the freezer and chill for approximately 90 minutes or until the bites are firm and frozen through.
In a small microwave-safe bowl, combine the dark chocolate chips and coconut oil; heat in 30-second intervals, stirring between each, until the chocolate is completely melted and smooth.
Remove the bites from the freezer and quickly dip each one into the melted chocolate or drizzle the chocolate over the top using a spoon.
Place the bites back onto the parchment paper and return to the freezer for an additional 30 minutes to allow the chocolate shell to set completely.
