01 - Line a mini muffin tin with paper liners or arrange silicone candy molds on a flat tray 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 free of any streaks.
03 - Using a small spoon or cookie scoop, fill each liner or mold with approximately 1 tablespoon of the yogurt-peanut butter mixture, smoothing the tops evenly.
04 - If desired, sprinkle dark chocolate chips and crushed peanuts over the top of each filled portion, gently pressing them into the surface so they adhere.
05 - Place the tray in the freezer on a level surface and freeze for at least 2 hours, or until each bite is completely firm and frozen through.
06 - Remove the bites from the freezer and allow them to rest at room temperature for 2 to 3 minutes before unmolding and serving for the best creamy texture.
