Ingredients needed & substitutions
This snickerdoodle-flavored oat milk smoothie recipe is made without yogurt and calls for four simple ingredients and ice cubes. Here is a list so you have everything prepared:
- Banana: Grab one large frozen banana and chop it up. This adds the best natural sweetness to this oat milk smoothie without needing to add any refined sugar! Plus, using a frozen banana makes this smoothie extra thick and creamy.

Expert tip for making a thick smoothie:
Here are a few expert tips for making super thick and creamy smoothies:
- Use frozen bananas. Use a chopped-up frozen banana to help thicken your smoothie naturally without adding a ton of ice. This trick makes super thick and creamy smoothies rather than icy ones.
- Start with the minimum amount of oat milk. You can always add more oat milk if you want a thinner smoothie. Start with 3/4 cup and add from there.
- Add chia seeds. If you want to make this smoothie extra thick, add a tablespoon or two of chia seeds, which will help soak up the liquid.
- Add a few cubes of ice. I never add more than 8 ice cubes to my smoothie because it can make them “icy” and not creamy. But adding a few helps make them thicker.
