Ripe mashed bananas bring natural sweetness and moisture to this snackable sheet cake, spiked with a touch of cinnamon and vanilla for warmth in every bite. The batter comes together with a simple flax "egg" for structure and a quick curdled-milk trick that keeps the crumb soft and tender without any fuss. Once baked, the cake cools into a springy, golden layer that's just waiting for a generous swipe of frosting whipped to a light, spreadable finish. Sliced into neat squares, it's the kind of easygoing dessert that travels well to potlucks, lunchboxes, or an afternoon coffee break. This one's a solid pick for a lactose free kitchen, letting you enjoy classic banana cake flavor and that rich, frosted top without a second thought.
