Best dairy free oat milk smoothie

Oat milk is so good! It is the perfect, creamy dairy-free alternative to regular cow’s milk. That’s why I am so excited to share this delicious smoothie recipe.

This sweet and refreshing oat milk smoothie is made with five simple ingredients: oat milk, peanut butter, banana, cinnamon, and ice cubes. It’s the ideal snack, breakfast, dessert, or post-workout treat. Let’s not forget it’s also healthy, vegan, gluten-free, and dairy-free!

You can even add college or protein powder to make it more of a meal and filling. Personally, I love this healthy smoothie as a late afternoon snack before dinner. It fills me up and leaves me feeling good.

I cannot wait to hear what you think about my favorite smoothie recipe! I drink this oat milk smoothie and this banana peach protein smoothie at least five times a week – it is that delicious!

Is oat milk gluten free?

Not all oat milk brands are gluten free. Make sure you buy “gluten-free certified” oat milk if you’re gluten-free. It’s essential to check that the oat milk is made from gluten-free rolled oats.

The ingredients

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.
• Oat Milk: We need 3/4 cups of your favorite oat milk. You can use a store-bought brand like Oatly or use homemade oat milk.
• Peanut Butter: We add peanut butter for healthy fats and to keep you full! You need 1 tablespoon.
• Cinnamon: This is my secret ingredient to making this oat milk smoothie taste like a snickerdoodle!
• Ice: You’ll need 4 – 8 ice cubes to thicken this smoothie. This is an optional ingredient, but I recommend it.
• Optional Add-Ins: Feel free to add 1 – 2 Tbsp chia seeds, 1 – 2 scoops of unflavored collagen, or 1 scoop of vanilla protein powder.

Ingredient substitution suggestions

Don’t worry if you are out of an ingredient or two. Here are my substitution suggestions:

Milk: Use almond milk, cashew milk, skim milk, or 2% cow’s milk.

Peanut Butter: Use almond butter.

Nut-Free: Make this smoothie nut-free by using sun butter instead of peanut butter.

How to make an oat milk smoothie

First, add all ingredients to a high-speed blender, with optional add-ins.

Tip for making a thick smoothie:

Here are a few expert tips for making super thick and creamy smoothies:

Use frozen banana. 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 cups 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.
