Add all of the ingredients to your blender in the order listed, or in the order recommended for your blender (liquid should be closest to blades and frozen furthest away).
Blend for 45-60 seconds or until very smooth.
Pour into cups and enjoy!
Notes
For a thicker smoothie, try slightly freezing your bananas first.
The vanilla can be omitted.
Best if enjoyed right after making, however, feel free to pour into popsicle molds and freeze for strawberry banana popsicles!
If the smoothie is too tart try adding a little honey and blending again.
Depending on the time of year you can switch frozen strawberries for fresh and use frozen bananas instead of fresh! That's a great option in the winter months.
