Prep time: 5 minutes
Blend time: 1 to 2 minutes
Total time: About 7 minutes
Servings: 1 large smoothie or 2 small servings
Ingredients
Primary Ingredients
Rolled oats or quick oats: ½ cup
Milk (dairy or plant-based): 1 cup
Frozen blueberries: 1 cup
Banana (medium, ripe): 1
Optional Ingredients and Common Add-Ins
Greek yogurt (plain or vanilla): ¼ to ½ cup
Honey or maple syrup: 1 to 2 teaspoons, to taste
Vanilla extract: ½ teaspoon
Ground cinnamon: ¼ teaspoon
Chia seeds or flax seeds: 1 tablespoon
Protein powder: 1 scoop (about 20–25 g)
Nut butter (almond or peanut butter): 1 tablespoon
Instructions
Prepare the oats. If you prefer a smoother texture, blend the oats alone in the blender for 10 to 15 seconds until they resemble coarse flour.
Add liquid first. Pour the milk into the blender. This helps the blades move more easily and prevents sticking.
Add fruit. Add the frozen blueberries and the banana, broken into chunks.
Add oats. Add the oats directly to the blender if you did not pre-blend them.
Add creamy elements. If using Greek yogurt or nut butter, add them at this stage.
Add flavor enhancers. Add vanilla extract, cinnamon, and sweetener if using.
Add nutritional boosters. Sprinkle in chia seeds, flax seeds, or protein powder if desired.
Blend thoroughly. Blend on high speed for 45 to 60 seconds, or until the smoothie is completely smooth and creamy.
Adjust consistency. Add a splash of milk if the smoothie is too thick, or a few ice cubes if it is too thin.
Serve immediately. Pour into a glass and enjoy right away for the best flavor and texture.
Tips
Use frozen blueberries for a cold, thick smoothie without ice.
Very ripe bananas add natural sweetness and reduce the need for added sugar.
