Creamy, tropical, and naturally sweet, this frozen treat is made entirely from fruit — no dairy, no eggs, no added salt, and none of the iodine-heavy ingredients that make so many desserts off-limits during a low-iodine protocol. Frozen bananas do all the heavy lifting here, blending into a silky, soft-serve-style base that's genuinely hard to believe is just fruit. Ripe mango brings a bright, sunny sweetness, while fresh ginger and a squeeze of lime juice cut through with just enough zing to keep things interesting. The whole thing comes together in a blender or food processor in just a few minutes, which means you can have a satisfying dessert without any complicated workarounds. If you prefer a firmer scoop, a short stint back in the freezer gets you there — no ice cream maker required. A few fresh mint leaves on top make it feel a little fancy, but honestly it's just as good eaten straight from the blender bowl.

At least 4 hours before serving, peel and slice the bananas into 1-inch rounds and spread them in a single layer on a parchment-lined plate or small sheet pan. Freeze until completely solid, at least 4 hours or overnight.
Remove the frozen banana slices and frozen mango chunks from the freezer and let them sit at room temperature for 3–5 minutes, until just slightly softened at the edges — they should still be frozen solid at the center.
