01 - Line a mini muffin tin with paper liners or arrange silicone candy molds on a flat, freezer-safe tray.
02 - In a large mixing bowl, whisk together the Greek yogurt, peanut butter, honey (or maple syrup), and vanilla extract until completely smooth and uniformly combined.
03 - Using a small spoon or cookie scoop, fill each liner or mold with approximately 1 tablespoon of the mixture, smoothing the tops evenly.
04 - If desired, sprinkle dark chocolate chips and/or crushed peanuts over the top of each filled cup, gently pressing to adhere.
05 - Transfer the tray to the freezer and chill for at least 2 hours, or until the bites are completely firm and frozen through.
06 - Remove from the freezer and let sit at room temperature for 2 to 3 minutes before serving to achieve the ideal creamy texture.
