Combine blueberries, yoghurt, honey and vanilla in a food processor or blender. Process until smooth, for about 2 minutes. Scrape down the sides and process again until smooth.
For a creamier frozen yoghurt serve immediately OR freeze for about 10 minutes in a tray/container until set. For an icier consistency, leave for up to 30 minutes, mixing through once to maintain creaminess.
Notes
Serve topped with fresh berries and nuts, in a waffle cone, or on its own! So many options.
