Ingredients

Apples. Cored and not peeled. The best apples to prevent a grainy texture are sweet and crispy, such as Gala, Fuji, Honeycrisp and even green Granny smith. Avoid mealy apples that seem bruised or over ripe.
Banana. Use a half of frozen banana that is peeled and unbruised.
Rolled oats. Quick oats are also fine; don't use steel cut.
Milk & milk ice cubes. I used coconut milk frozen in ice cube trays and oat milk as the liquid addition. You can choose your favorite. Coconut milk does not add a coconut flavor to this smoothie, but does add a smooth creamy texture and healthy fats.
Peanut butter. Just a tablespoon will increase the protein levels.
Cinnamon. Important to help temper the sweetness of the apple.

Step 1: Add all ingredients to a blender. This smoothie makes about 8 ounces, enough for one person. Double it for two people or for a larger smoothie.

Step 2: Process until smooth, typically about 30-45 seconds in a high-speed blender. Taste and add sweetener if you want it sweeter, or additional milk if you want it less thick. Pour into a glass and enjoy!

Variations

Leafy greens. It will change the color but not the flavor if you add a small handful of raw spinach, kale or just spring mix.
You can add ½ a pitted and peeled raw avocado for nutrition and a creamy texture. It will add a green hue to your smoothie but won't change the flavor.
Intensify the apple flavor by adding ¼ cup of apple cider or apple juice.

FAQS

Can I mix banana and apple together?

Apple and banana complement each other perfectly, with apples adding a crisp sweet flavor, and banana providing a creamy sweet element.

Can you put apple core in smoothie?

No, the core is too rough for a smoothie, and you should not add apple seeds as they contain trace elements of amygdalin, a substance that can form a poison when it comes in contact with stomach acids.

What apples are best for smoothies?

Gala, Honeycrisp, Fuji and Granny smith are the best apples for an apple smoothie because they are crisp, and combined with creamy banana, are less likely to lead to a grainy smoothie texture.
