This is a genuinely simple no-churn dessert that lives up to its 15-minute claim if you use frozen fruit, which both bananas and mangoes are readily available year-round at every Charlotte chain. The cost per serving runs about $1.25–$1.50 depending on whether you buy premium fruit, making it one of the cheapest desserts in the rotation. The real limitation is that it demands same-night eating; the texture breaks down badly by day two, and reheating is impossible, so plan this only when you know everyone will be home to eat it fresh.
