What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 1 whole medium apple peeled and chopped
  • 0.5 cup rolled oats
  • 1 cup apple juice
  • 0.5 cup plain Greek yogurt
  • 0.5 teaspoon ground cinnamon
  • 0.5 whole frozen banana

Step by step instructions

Step 1: Soak the Oats

Place the rolled oats and apple juice into the blender and let them soak for 2 minutes. This brief soaking helps the oats blend more smoothly and prevents a gritty texture.

Step 2: Add Remaining Ingredients

Add the chopped apple, frozen banana, Greek yogurt, and ground cinnamon to the blender with the soaked oats.

Step 3: Blend Until Smooth

Blend on high speed for 90 seconds. Oats require longer blending time than fruit alone so do not cut this step short or the smoothie will have a gritty texture kids do not enjoy.

Step 4: Serve and Garnish

Pour into glasses and sprinkle a tiny pinch of cinnamon on top for presentation. This smoothie is thick so serving with a wide straw or spoon straw works best.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • rolled oats → quick oats for an even smoother texture that requires less blending time
  • apple juice → unsweetened applesauce for a thicker and more concentrated apple flavor

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Skipping the oat soaking step which results in a gritty and unpleasant texture kids will reject
  • Using steel cut oats instead of rolled oats which do not blend properly even with extended blending time
