Make sure the bananas and strawberries are completely frozen before blending. This step is key for achieving a thick and spoonable texture. I always keep frozen fruit ready to save time.
Add frozen bananas, strawberries, milk, and optional ingredients to your blender. Blend until smooth, stopping to scrape the sides if needed for even blending.
If the mixture feels too thick, add a small splash of milk and blend again. Do this slowly so the smoothie stays thick and creamy.
Spoon the smoothie into a bowl and smooth the surface. This makes it easier to add toppings neatly and attractively.
Top with fresh fruit, granola, or seeds and serve immediately. The texture is best when enjoyed fresh and cold.
