Ingredients
Scroll down to the recipe card below for full information on ingredients and amounts.
- Oatmeal - I like old fashioned or rolled oats but quick cooking oats will work just as fine. Stay away from steel cut variety, as it will be hard to blend and is more difficult to digest when raw.
- Banana - As with all ripe banana recipes, use ripe or overripe bananas. They’re sweeter and creamier! For a thicker, creamier oatmeal smoothie, use frozen bananas. They’ll create a frothy texture that’s reminiscent of a decadent chocolate milkshake.
- Milk - Just the right amount of milk makes this chocolate banana oatmeal smoothie blend up perfectly and also naturally thicken.
- Cocoa powder - As in all cocoa powder recipes, I used Hershey's 100% cocoa. You can find two types of cocoa in the market - Dutch processed and natural variety. Natural cocoa is acidic with an intense flavor and lighter in color whereas, dutch processed has a milder, less bitter flavor and more darker in color. In general, I like the less harsh dutch processed cocoa in this oatmeal banana smoothie recipe for a well rounded and smooth tasting drink.
- Vanilla extract - Elevates it to taste like a dessert shake.
Pro Tip: Ounce for ounce, cocoa powder has more cocoa solids and hence more chocolate flavor than any other type of chocolate.
Substitutions
- Make it vegan by using almond or oat milk and maple syrup instead of honey.
- Add peanut butter or almond butter for added protein and creaminess.
- Add ¼ teaspoon cinnamon instead of vanilla extract.
- Use frozen banana for an ultra-creamy milkshake like consistency.
- Add a small scoop of your favorite protein powder.

Storage

If you like to make ahead for a busy day, you can also freeze the blended drink in an ice cube tray or freezer-safe container.

Can I use Maple syrup instead of honey
Maria Doss
Hi Adele, Of course! We preferred the taste of honey better than maple syrup in this oatmeal smoothie recipe, but use whatever you have on hand. Have a wonderful day - Maria

What can I use instead of banana?
Maria Doss
Hmmm, I apologize, but this recipe relies on bananas for their natural sweetness, creaminess, and flavor. If you'd like, you can try substituting some of the banana with yogurt and adding extra sweetener to taste, though the texture and flavor may differ - Maria
