What you will need

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

  • 1 cup frozen blueberries
  • 1 large ripe banana
  • 0.33 cup old fashioned rolled oats
  • 1 cup milk of choice
  • 0.5 cup vanilla yogurt
  • 1 tablespoon honey

Step by step instructions

Step 1: Soak the Oats

Add the rolled oats to the blender with the milk and let them soak for two minutes. This softens the oats so they blend into a completely smooth texture without any grittiness.

Step 2: Add Remaining Ingredients

Add the frozen blueberries, banana, vanilla yogurt, and honey directly into the blender on top of the soaked oats.

Step 3: Blend Until Creamy

Blend on high for 60 to 90 seconds until the smoothie turns a deep vibrant purple and is completely smooth with no oat pieces visible.

Step 4: Serve and Enjoy

Pour into glasses and serve immediately. Kids love the gorgeous purple color and you can top with a few fresh blueberries for a pretty presentation.

Easy substitutions

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

  • old fashioned rolled oats → certified gluten free oats for children with gluten sensitivity
  • vanilla yogurt → plain Greek yogurt plus a small splash of vanilla extract for less sugar

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not soaking the oats first which leaves the smoothie with a grainy unpleasant texture that kids will reject
  • Using too many oats which makes the smoothie overly thick and difficult for small children to drink through a straw
