01 - Line a mini muffin tin with paper liners or set out silicone candy molds for easy release after freezing.
02 - In a large mixing bowl, whisk together the Greek yogurt, peanut butter, honey (or maple syrup), and vanilla extract until the mixture is completely smooth and well 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 the tops with dark chocolate chips and/or crushed peanuts, gently pressing them into the surface so they adhere.
05 - Place the tray in the freezer for at least 2 hours, or until the bites are completely firm and frozen through.
06 - Remove from the freezer and let the bites sit at room temperature for 2–3 minutes before eating for the creamiest texture.
