Banana Mille Feuille is a classic French dessert made with layers of crispy puff pastry, creamy vanilla pastry cream, and fresh bananas. The puff pastry is baked until golden and flaky, then layered with the smooth and luscious pastry cream. Sliced bananas are added between the layers, adding a natural sweetness and a hint of freshness. This elegant dessert is perfect for special occasions or as a sweet treat to impress your guests.
