Prepare your ingredients: Start by slicing the bananas into smaller pieces to help them blend smoothly. If you want an extra thick texture, freeze the banana slices for at least 30 minutes before blending. This gives the smoothie that signature thick and frosty consistency.

Add ingredients to the blender: In a high-speed blender, combine the milk, dry milk powder (if using), vanilla ice cream, honey, peanut butter, vanilla extract, and banana slices. Top with ice cubes. This layering helps the blender catch all ingredients easily without overworking the motor.

Blend until smooth and creamy: Blend on medium speed for about 30 seconds, then increase to high speed for another 30–45 seconds, or until the mixture looks silky, thick, and lump-free. Stop halfway to scrape down the sides if needed. The consistency should be rich and spoonable, similar to a milkshake.

Adjust the texture: If the smoothie is too thick, add a splash more milk and blend again for a few seconds. If you prefer it thicker, add a few more ice cubes or a bit more ice cream. Taste and adjust the sweetness with a drizzle of honey or maple syrup.

Serve immediately: Pour the Banana Boat smoothie into two tall glasses. For a fun presentation, top with a swirl of whipped cream, banana slices, or a drizzle of peanut butter on top. Serve right away while cold and creamy.
