This “Hulk smoothie” is not only a fun green color but a balanced breakfast or snack! It is made with rolled oats which will help keep your little ones full. When my little guys aren’t in the mood for a full breakfast, or when I’m looking for a filling option to serve to help get them to dinner time, a smoothie is always a go-to. Rolled oats are packed with fiber and whole grains and peanut butter contains protein and healthy fats for a well-balanced treat!

WHAT YOU’LL NEED

Here is what you’ll need to make this spinach banana smoothie:

Ingredients to make spinach banana smoothie.
  • Spinach: For added nutrients and vitamins. The star ingredient that gives this smoothie that bright green color.
  • Bananas: The main source of sweetness for this smoothie. Try to use bananas that are very ripe with several brown spots. The riper the bananas, the sweeter the smoothie!
  • Rolled Oats: Packed with fiber and whole grains to make this smoothie filling. Gluten-free rolled oats make this smoothie gluten-free.
  • Milk: I used whole milk in this recipe, but dairy-free alternatives work as well.
  • Cinnamon: Warm spice for added flavor.
  • Peanut Butter: For added flavor, protein, and healthy fats. Try to look for a natural peanut butter that lists only peanuts as the ingredient. My favorite type of peanut butter to use is the Kirland brand organic natural peanut butter.
  • Ice Cubes: For thickness and a chilly texture to the smoothie.

PROCESS

  1. Add all of the ingredients to a blender and blend until smooth. If the mixture is thick and hard to blend, add in a little more milk.
  2. Pour into cups and serve!

STORAGE INSTRUCTIONS

This smoothie is best enjoyed fresh, but you can store it in an airtight container in the freezer for up to 1 month. When ready to serve, you can thaw it overnight in the fridge or let it thaw out at room temperature for a few hours. When you are ready to drink it, just give it a quick shake! You can also store the smoothie in an ice cube tray, freeze the cubes in an airtight container and blend a few cubes with a little splash of milk once you are ready to drink it!

SUBSTITUTIONS

  • Milk: You may substitute the milk with any dairy-free alternative such as oat milk or coconut milk.
  • Peanut Butter: The peanut butter may be replaced with any type of nut butter or seed butter. You can also omit it altogether!

RECIPE NOTES

  • Make sure to use overripe bananas for the best natural sweetness. You can add in a little maple syrup if you’d like for more sweetness, but I find that the bananas provide plenty of natural sweetness on their own when ripe with brown spots.
  • Make sure to blend the smoothie until it is completely smooth and there are no chunks of oats remaining. I love using this nutribullet blender combo to blend the mixture into a smooth consistency.
  • You may use frozen bananas for this smoothie. If you are using frozen bananas, you may want to either use a little less ice or add a little more milk to help it blend well.
  • I love serving these smoothies in these toddler glass tumbler jars with silicone sleeves. They are the perfect size smoothie servings for little ones and easy for them to grip and hold!
