This oatmeal smoothie is creamy, spiced with cinnamon, and naturally sweet from banana. It’s quick to make and loaded with over 20 grams of protein, making it a satisfying option for breakfast or post-workout fuel.
Place banana, milk, oats, protein powder, cinnamon, and vanilla in a high-powered blender and blend until smooth.
If the smoothie is too thick, add a little more milk.
Pour into a glass or bowl (depending on whether you want to use a spoon or straw) and top with your favorite smoothie toppings.
Notes
No banana? Frozen banana makes this smoothie sweet and creamy, but you’ve got options! Try using ice or frozen milk cubes for texture, or frozen cauliflower rice, frozen zucchini, or a bit of avocado for creaminess. Just note that if you skip the banana, you’ll likely want to add a little extra sweetener like maple syrup, honey, or dates.
Oats: Rolled oats or quick oats both work well and blend easily. Skip steel-cut oats, which are harder to blend and not ideal for smoothies.
Protein powder: I like vanilla protein powder here because it boosts the flavor and helps make the smoothie more filling.
Storage: This smoothie is best enjoyed right after blending, but you can store leftovers in a sealed jar in the fridge for up to 24 hours. Give it a good shake before drinking.
