FAQs

Can I use instant oats instead of rolled oats?

Yes, instant oats will blend more quickly, but rolled oats provide a slightly nuttier flavor.

Do I need to soak the oats first?

No, blending them dry works fine, but soaking them for 10 minutes in milk can make the smoothie creamier.

Can I make this smoothie vegan?

Yes, simply use plant-based milk like almond, soy, or oat.

Will frozen bananas work?

Yes, frozen bananas make the smoothie extra cold and creamy.

Can I add sweetener?

You can, but usually the banana provides enough natural sweetness.

Can I make a bigger batch?

Yes, just multiply the ingredients and store leftovers in the fridge for up to a day.

Can I use steel-cut oats?

No, steel-cut oats are too coarse and won’t blend well unless cooked first.

Can I add ice to this smoothie?

Yes, adding ice will make it thicker and more refreshing.

Is this smoothie good for weight loss?

Yes, it’s high in fiber and can keep you full, making it a healthy option for weight management.

Can I meal prep this smoothie?
