In an ice cream machine or a large airtight container, combine the first five ingredients: yogurt, vanilla extract, sweetener, cherries, and optional chocolate. If using an ice cream machine, churn according to the manufacturer's instructions for a creamier texture.
Mix until well combined, observing the mixture's consistency. It should be smooth and creamy. If you're using a container, stir vigorously to ensure all ingredients are blended thoroughly.
If you're using an ice cream machine, transfer the churned mixture to an airtight container once it's done, ensuring to smooth the top with a spatula.
Seal the lid tightly and place the container in the freezer. If you’re not using an ice cream machine, let the mixture sit in the container while you prepare to freeze it.
If not using an ice cream machine, stir the contents every hour for up to three hours. This will help achieve a smoother texture without ice crystals forming.
Once ready, you can eat immediately for a soft-serve texture, or freeze for an hour for a firmer consistency.
Store any leftovers in the airtight container. It can keep for up to a month, but remember to thaw for 15 to 30 minutes before serving to allow it to soften.
If you want to get creative, consider adding toppings like additional cherries, nuts, or granola just before serving.
