Ensure the bananas are peeled and frozen prior to making the smoothie. If they're not frozen, consider adding a handful of ice cubes to chill the smoothie.

In a high-speed blender, add the frozen bananas, creamy vanilla protein powder, old-fashioned oats, pitted Medjool dates, roasted almond butter, fragrant cinnamon, and unsweetened almond milk.

Start blending the ingredients on low speed to break them down. Gradually increase the speed to high and blend for 1-2 minutes or until the mixture becomes smooth and creamy. Make sure all ingredients are well incorporated.

Pause the blender and check the consistency of the smoothie. If it's too thick for your liking, add a splash more almond milk and blend again until you reach the desired consistency.

Taste the smoothie and adjust the sweetness or flavor if needed. You can add an extra date for more sweetness or a pinch more cinnamon for extra flavor.

Once satisfied with the taste and consistency, pour the smoothie into glasses. Optionally, you can sprinkle a dash of cinnamon on top for garnish.

Serve the almond milk smoothie immediately while it's fresh and enjoy it as a nutritious and satisfying meal or snack.
