Filled with decadent layers of velvety cream pastry, known as crème pâtissière, and ripe banana slices filling up the crust, this succulent no-bake banana cream pie is a must for the holidays. This take on the classic banana cream pie is easy-to-prepare as you can forget about the oven and prepare the delicious crust from scratch with ground vanilla cookies, butter, pecans, nutmeg, and a pinch of salt.
