Traditional Banana Pudding

Why This Traditional Banana Pudding Works

As the sugar, flour, salt, and milk heat on the stove, the flour swells and thickens the milk. After a few minutes, the thin liquid slowly changes into a smooth, thick custard that can sit on top of bananas and wafers without running all over the place. When the warm custard is mixed into the egg yolks and then cooked a bit more, the yolks set the custard so it stays creamy but firm instead of soupy.

Once the custard is ready, it sinks down around the banana slices and vanilla wafers. Over time, the warm custard soaks into the wafers, softening them so they taste almost like cake. In the oven, the egg whites and sugar puff up into a light meringue that sets on top and seals the pudding underneath. That meringue lid keeps the inside warm and lets the layers finish softening together, so the pudding slices nicely and has that classic soft, spoonable texture.

Mistakes To Avoid

Letting the milk, sugar, and flour mixture boil hard or sit without stirring makes it scorch on the bottom and turn lumpy. Once that happens, the custard gets grainy and thick in some spots and runny in others, so the pudding never sets into a smooth layer.

Adding the hot milk mixture to the egg yolks too fast causes the yolks to cook in little bits instead of blending in. This leaves tiny scrambled egg pieces in the custard, so the texture turns curdled instead of silky.

Layering warm custard over very thin or overripe banana slices makes the bananas break down quickly. The slices turn mushy and start to leak liquid into the dish, so the layers get watery and the wafers lose all structure.

Whisking the egg whites in a bowl that has any grease or yolk left in it keeps them from whipping up fully. The meringue then stays soft and foamy, so it doesn’t hold stiff peaks and can collapse or weep liquid over the pudding in the oven.
