In a mixing bowl, combine Greek yogurt and peanut butter. Add honey or maple syrup and vanilla extract if using. Stir until smooth.

Taste and adjust sweetness if needed. Mix in optional ingredients like chocolate chips or dried fruits.

Portion out small dollops of the mixture onto a parchment-lined tray, leaving space for freezing.

Shape each portion into a smooth ball or flatten slightly, ensuring even distribution of mix-ins.

Place tray in the freezer for at least 2 hours or until firm.

Transfer frozen bites to an airtight container or resealable bag. Label and return to freezer for up to 2 weeks.
