Peel your bananas and slice them into half-inch rounds. Rinse your apple under cool water, then cut it in half, core out the seeds, and chop it into rough one-inch chunks (leaving the skin on adds fiber and nutrients).

Pour your milk into the blender base before adding solids, which helps the blades engage more smoothly and prevents stalling.

Spoon your Greek yogurt directly into the blender on top of the milk.

Add your sliced banana and chopped apple pieces to the blender.

Sprinkle in your vanilla extract, cinnamon, and honey if you're using them.

Toss in four to six ice cubes if you want a thicker, colder smoothie with a more milkshake-like consistency. Skip the ice if you're using frozen bananas or if you prefer a thinner, more drinkable texture.

Secure your blender lid and blend on high speed for 45 to 60 seconds, until no chunks of fruit remain and the smoothie looks uniform in color and texture. If your blender is struggling, pause, stir with a spoon, and blend again briefly.

Carefully pour the smoothie into two serving glasses right away, as it will separate if left sitting. A quick stir before drinking ensures you get the full creamy experience rather than milk pooling at the bottom.
