Method
Break 2 Weet-Bix into a 300-400 ml jar and crush them roughly with a fork, leaving a few bigger pieces for texture.
Pour 1/3 cup (80 ml) milk evenly over the crumbs, wait 30 seconds, then press down firmly into a flat, even base.
In a small bowl, stir 1/2 cup (130 g) Greek yoghurt with the honey and vanilla until smooth and creamy.
Spoon the yoghurt over the Weet-Bix base and spread it right to the edges of the jar so it seals the base.
Top with diced mango or berries. Add banana in the morning instead, as it turns brown overnight.
Cover and refrigerate for at least 4 hours or overnight (6-8 hours), until the base is soft and cake-like. Eat cold within 2 days.
