Place all ingredients except rolling garnishes into the Thermomix bowl and blend 10 sec/speed 6. Scrape down sides of bowl and repeat. Scrape this mixture into a flat container and freeze for at least 4 hours.
Place all the rolling ingredients into different bowls as needed.
Remove the mixture from the freezer and if it will not ball up easily using a tablespoon, leave in the freezer until it will. Use slightly damp hands to roll a tablespoon of the mixture at a time, then toss gently in toppings of choice. Store in the freezer.
