Place the frozen banana pieces and any optional add-ins into the Thermomix bowl.
Mix for 15 seconds, slowly working your way up to Speed 8.
Scrape down the sides of the bowl and mix for a 1 minute, Speed 4, or until smooth and creamy. Serve immediately or store in the freezer until ready to serve.
Notes
RECIPE NOTES & TIPS:
If you don't have a Thermomix, you can use a food processor or blender. Chop bananas into smaller (2cm) pieces if using a food processor or blender.
Chop peeled bananas before freezing - this makes blending easier.
Freeze bananas fully (at least 1–2 hours, ideally overnight) for best results.
Add optional flavours before mixing.
Scrape the sides of the bowl down to ensure an even, creamy texture.
Serve immediately for soft-serve style — this is when it’s at its best.
If freezing leftovers, allow to sit at room temp for a few minutes before eating.
Double or triple the recipe easily — just increase mixing time slightly.
Nutritional info is based on using frozen bananas only (and does not include optional add-ins).
