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.
• Oat Milk: You can use a store-bought brand like Oatly or use homemade oat milk. Use can substitute the oat milk with almond milk, cashew milk, skim milk, or 2% cow’s milk.
• Peanut Butter: We add peanut butter for healthy fats and to keep you full! It also adds the best flavor. You can substitute the peanut butter with almond butter or sun butter if you are nut-free.
• 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.
