If you can't find any honey, you can use sugar, agave nectar, stevia, or even maple syrup instead. If you are using frozen bananas, then you can skip the ice cubes—unless you like really thick smoothies. There should be no lumps or clumps. From time to time, you may have to pause the blender, open it up, and push the ingredients down the sides with a rubber spatula. Depending on what type of blender you have, you may need to choose a setting, such as: "smoothie," "blend," or "puree." You can enjoy it as it is, or you can garnish it with a dollop of whipped cream, banana slices, or a drizzle of honey. 

Now, please write a short abstract for it in Vietnamese. Abstract:
Bóc và cắt lát một quả chuối, sau đó bỏ vào máy xay sinh tố. Cho thêm sữa và mật ong. Cho đá vào sau cùng nếu thích. Xay các nguyên liệu cho đến khi mọi thứ sánh mịn và quyện đều. Rót sinh tố vào cốc và dọn lên.
