Why you’ll love this oatmeal cookie smoothie
This smoothie is my favorite weekday treat because it feels indulgent without the sugar crash. Think warm-cinnamon cookie shop aroma, but in a cool, sippable format. The texture is thick and milkshake-like thanks to oats and a frozen banana. If you need something filling, the fiber from oats and healthy fats from nut butter keep you full for hours. Bonus: no oven, no mess, and no waiting for cookies to bake.
It’s also a friendly recipe for the whole family. Kids think it tastes like dessert. Adults appreciate how steady the energy is. You can keep it super classic or give it a nutrition boost with protein powder, flax, or chia. If you love creamy, comfort-style blends, you might also enjoy my go-to creamy oatmeal breakfast smoothie on slower mornings.

What delicious and healthy ingredients are in this smoothie?
Here’s the simple lineup that gives this smoothie its oatmeal cookie magic and staying power.
Base ingredients
- Rolled oats: They blend silky and add that cookie-dough vibe. Rolled or old-fashioned oats work best.
- Frozen banana: For sweetness and creaminess without ice cream. If you dislike banana, see the swaps below.
- Milk of choice: I love unsweetened almond or oat milk for a cozy flavor. Any milk works.
- Greek yogurt or dairy-free yogurt: Adds protein and tang that balances sweetness.
Cookie-inspired flavors and boosts
- Cinnamon and vanilla: The classic cookie combo. A pinch of nutmeg makes it extra nostalgic.
- Nut butter: Peanut butter is comforting; almond or cashew butter taste a bit more cookie-like. Start with 1 to 2 tablespoons.
- Sweetener to taste: Dates, maple syrup, or honey. Sometimes the banana is sweet enough on its own.
- Optional add-ins: Ground flaxseed or chia seeds for extra fiber and omega-3s. A small pinch of salt makes the flavors pop.
- Ice: Only if you want it extra thick and frosty.

How to make this oatmeal cookie smoothie
You’re 3 minutes from sipping something seriously satisfying. Here’s my simple method.
- Add to blender in this order for best texture: milk, yogurt, nut butter, vanilla, cinnamon, oats, then frozen banana. If using dates or seeds, add them with the oats.
- Blend on low to start, then increase to high until completely smooth, about 45 to 60 seconds. If the blender stalls, add a splash more milk.
- Taste and adjust. Want sweeter? Add a date or a drizzle of maple. Want thicker? Add a few ice cubes or extra frozen banana. Want thinner? Add more milk a little at a time.
- Pour and sip right away for the best cookie-shop aroma and frosty texture.
Small tip that makes a big difference: if you have a minute, soak the oats in the milk for 5 to 10 minutes first. It softens them for an ultra-smooth blend.
For busy mornings, make freezer packs with measured ingredients so you can dump and blend. It’s the easiest way to stick to a routine that feels good.
Expert tips
These are the little tweaks that make this recipe taste like a treat and fit your goals.
Make it yours
For a stronger cookie vibe: add a tiny pinch of salt and a bit more vanilla. If you like snickerdoodle flavors, a touch of nutmeg or half a teaspoon of brown sugar can be fun.
For extra protein: add a scoop of vanilla protein powder or 2 tablespoons of Greek yogurt. If you use protein powder, you may need a splash more milk.
For banana-free: swap with frozen pears or frozen apples for a similar sweetness. In that case, a half date or a teaspoon of maple syrup helps round out the flavor.
For dairy-free: choose almond, cashew, or oat milk and dairy-free yogurt. It stays just as creamy.
For gluten-free: use certified gluten-free oats. Simple and safe.
Flavor spinoffs worth trying
If you love cozy flavors, you’ll probably fall for this apple cinnamon oatmeal smoothie too. It tastes like a fall bakery in a cup. If you crave something fruity on rotation with your cookie smoothie, try a green-fruit spin like this vibrant blueberry spinach smoothie for more antioxidants.
How to store
This smoothie is best right after blending, but you can absolutely make it ahead.
Fridge: Store in an airtight jar for up to 24 hours. Re-shake or re-blend with a splash of milk before drinking. A tiny squeeze of lemon can help keep flavors bright.
Freezer: Pour leftovers into an ice cube tray. Freeze and re-blend later with a bit of milk for instant smoothie. It’s also perfect for making thick smoothie bowls.
Prep packs: Measure oats, cinnamon, and seeds into small bags or jars. Freeze banana halves separately. In the morning, you only add milk, yogurt, and nut butter. It turns a busy morning into an easy win.
Common Questions
Does it really taste like an oatmeal cookie? Yes, the cinnamon, vanilla, and oats give a cookie-dough taste, especially with a pinch of salt and nut butter.
Can I use quick oats or steel-cut oats? Quick oats work well. Steel-cut oats aren’t ideal unless soaked overnight because they can stay gritty.
What can I use instead of banana? Try frozen pears or apples. If needed, balance sweetness with a date or a bit of maple syrup.
How do I make it higher protein? Add Greek yogurt, cottage cheese, or a scoop of protein powder. You can also toss in hemp seeds.
I want a fruitier vibe. Suggestions? Blend in a handful of strawberries or follow this classic strawberry banana smoothie recipe on days you want bright and fresh.
