This classic recipe produces a delightful two-layer banana cake, featuring a moist and tender crumb bursting with natural banana flavor. It is generously topped with a rich, smooth, and wonderfully fluffy cooked vanilla pudding-based icing, creating a timeless dessert perfect for any occasion.
For optimal flavor, use very ripe, spotty bananas; they provide more sweetness and a deeper banana aroma. Ensure all cold ingredients for the cake, especially eggs and buttermilk, are at room temperature for a smoother, better-emulsified batter. When folding in the beaten egg whites, do so gently to maintain their airiness, which contributes to the cake's light texture. For the icing, it is critical that the cooked vanilla pudding is completely cooled to room temperature before being added to the creamed butter mixture; otherwise, the icing will be runny and difficult to set. Mixing the icing with an electric mixer for the full 15 minutes is key to achieving a smooth, non-grainy, and fluffy consistency. For an enhanced flavor profile, consider adding a pinch of cinnamon or nutmeg to the cake batter.
