1. Prepare your ingredients: Ensure your strawberries are frozen and your banana is peeled and frozen. If your banana isn’t frozen, you can still use it, but you might want to add a few ice cubes to achieve a colder, thicker smoothie.

2. Add liquids first: Pour the milk into your blender. If you’re using Greek yogurt, add that in now as well. Adding liquids first helps the blades move more freely and prevents ingredients from getting stuck at the bottom.

3. Introduce the frozen fruits: Carefully add the frozen strawberries and the frozen banana pieces into the blender. Distribute them evenly over the liquid base.

4. Add the protein powder and sweetener: Spoon in your scoop of vanilla protein powder. If you’re using honey or maple syrup for extra sweetness, drizzle it in now.

5. Blend until smooth: Secure the lid on your blender and start blending on a low setting, gradually increasing to high. Blend until all ingredients are completely smooth and creamy, with no chunks of fruit remaining. You might need to stop and scrape down the sides with a spatula once or twice to ensure everything is incorporated.

6. Check consistency and adjust: If the smoothie is too thick, add a splash more milk (one tablespoon at a time) and blend again until desired consistency is reached. If it’s too thin, add a few more frozen strawberries or a couple of ice cubes.

7. Serve immediately: Pour your freshly blended strawberry banana protein smoothie into a glass and enjoy right away. The best texture and flavor are achieved when consumed immediately after blending.
