To flash-freeze bananas, slice them and lay them in a single layer on a parchment-lined baking sheet. Place in the freezer for 2 hours. Transfer frozen banana slices to a container with a lid or a zip-top bag and freeze. Use within 2 months.

Prep Tips

  • Appliance: I use the Ninja Home System blender attachment.
  • Make the oat topping first and allow it too cool while you blend the smoothie bowl.

First, make the toasted oat topping so it can cool.

  1. Heat a skillet over medium heat.
  2. Melt the butter and add the oats, toasting while stirring for 4-5 minutes.
  3. Add the maple syrup, cinnamon, nutmeg, and salt. Heat through, stirring, for about a minute.
  4. Transfer to a bowl or plate and allow to cool to room temperature.

  1. Add the rest of the ingredients and blend for about 60 seconds or until smooth and fully blended. Pause to scrape the sides down as needed. Add extra liquid only a tablespoon at a time if needed to help with blending.

Pour the smoothie mixture into a bowl and top with a tablespoon of the cooled oats. Add a chopped date and swirl of melted peanut butter if you want to garnish it more, or just serve.

Tips for Making Smoothie Bowls

  • Ripe bananas are naturally sweeter and blend more smoothly. Slice them before freezing to make blending easier. My grocery store also sells frozen banana slices.
  • Frozen fruit is one of the keys to a super thick and creamy smoothie bowl!
  • Add minimal liquid for a thicker smoothie bowl. Add additional liquid by the tablespoon when needed for blending.
  • Customize the toppings to suit your taste. A sliced fresh banana is great with this smoothie bowl. Raspberries or sliced strawberries would be great also.

Storage

It’s best to make smoothie bowls as needed, they will melt when kept in the fridge. The oat toppings can be made in advance and stored at room temperature for a few weeks.

Frequently asked questions

Can I make this smoothie bowl nut-free?

Yes! To make this smoothie bowl nut-free try tahini, pumpkin seed butter, or sunflower seed butter in place of the peanut butter, or skip it altogether.

Notes

Adjust the thickness to your preference. Smoothie bowls are generally thicker than smoothies because you garnish them and eat them with a spoon instead of drinking with a straw.
To make it a thinner drinkable smoothie, add more liquid, skip the garnishes, and pour into a glass.
To make a thicker smoothie bowl, don’t add all of the liquid or add more frozen fruit and blend as needed.
