Start by gathering all the ingredients and measuring them properly. Make sure the banana and blueberries are frozen, as this helps create a thicker and colder smoothie without needing ice. Frozen fruits also enhance the creamy texture naturally.
Pour the almond milk into the blender first to help the blades move easily. Then add Greek yogurt, oats, frozen blueberries, and the frozen banana. Adding liquid first helps everything blend smoothly and prevents ingredients from sticking.
Blend the mixture on high speed until completely smooth and creamy. This usually takes about 30–60 seconds depending on your blender. If the smoothie feels too thick, add a small splash of almond milk to adjust the consistency.
Taste the smoothie and decide if you want additional sweetness. If needed, add a teaspoon of honey, agave nectar, or stevia and blend again for a few seconds. Often the banana and blueberries provide enough natural sweetness.
Pour the smoothie into a tall glass or smoothie jar. For presentation, you can sprinkle a few oats or fresh blueberries on top. Serve immediately while it’s cold and creamy for the best flavor and texture.
