Oatmeal Raisin Smoothie – Cozy, Cookie-Inspired Breakfast in a Glass
If you love the warm, nostalgic flavor of oatmeal raisin cookies but want something lighter and more nourishing, this smoothie hits the sweet spot. It’s thick, creamy, and naturally sweet from raisins and banana, with just a hint of cinnamon. The oats make it hearty enough to keep you full, while the milk and yogurt add satisfying creaminess.
It’s fast, simple, and tastes like comfort—without turning on the oven.

Ingredients
Method
- Soak the raisins (optional but recommended): Add raisins to a small bowl and cover with hot water for 10 minutes. Drain well. This softens them and blends away any chewiness.
- Pre-grind the oats (optional for ultra-smooth texture): Pulse rolled oats in the blender until they look like a fine flour. This helps the smoothie turn silky.
- Load the blender: Add milk, yogurt, banana, soaked raisins, oats, vanilla, cinnamon, and a pinch of salt. If you want an extra-cold smoothie, add ice.
- Blend until completely smooth: Start on low, then increase to high for 45–60 seconds. Scrape down the sides if needed and blend again.
- Taste and adjust: Add maple syrup or honey if you want more sweetness. If it’s too thick, splash in more milk. If it’s thin, add a few ice cubes or another spoonful of oats and blend again.
- Serve immediately: Pour into a chilled glass. For a cookie-like finish, sprinkle a little cinnamon on top.
What Makes This Special

This smoothie takes the familiar taste of an oatmeal raisin cookie and turns it into something fresh and wholesome. The raisins act like little flavor bombs, blending into a caramel-like sweetness that pairs perfectly with cinnamon and vanilla. Rolled oats bring a chewy, grainy depth—but when blended well, they become silky and satisfying.
It’s also a great make-ahead option, especially if you soak the raisins and oats overnight.
The result is a smooth texture that feels indulgent, yet it’s full of whole grains and fiber. Best of all, you can adapt it to your routine: drink it as breakfast, sip it after a workout, or enjoy it as a snack that actually fills you up.
Ingredients
- 1/2 cup rolled oats (old-fashioned; not instant)
- 1/3 cup raisins (golden or regular)
- 1 medium ripe banana (frozen for extra creaminess)
- 1 cup milk (dairy or unsweetened almond, oat, or soy)
- 1/2 cup plain or vanilla yogurt (Greek for extra protein, or regular)
- 1–2 teaspoons pure maple syrup or honey (optional, to taste)
- 1 teaspoon vanilla extract
- 1/2–1 teaspoon ground cinnamon
- Pinch of salt (balances sweetness)
- 4–6 ice cubes (optional, for a colder, thicker texture)

How to Store
This smoothie tastes best fresh, but you can store leftovers in an airtight jar for up to 24 hours in the fridge. The oats will continue to thicken the mixture as it sits. If it becomes too thick, stir in a splash of milk before drinking.
For meal prep, blend everything except the ice, then refrigerate.
Give it a shake and freshen it up with ice or more milk right before serving. You can also freeze smoothie portions in silicone molds or jars for up to a month and thaw overnight in the fridge.

Benefits of This Recipe
- Whole-grain goodness: Rolled oats bring fiber and beta-glucan, which can support steady energy and fullness.
- Natural sweetness: Raisins and banana sweeten the smoothie without relying on refined sugar.
- Protein options: Greek yogurt or soy milk boosts protein, making it a balanced breakfast or post-workout drink.
- Comforting flavor: Cinnamon and vanilla mimic classic cookie vibes without being heavy.
- Easy to customize: Works with dairy-free milks, add-ins like protein powder or chia seeds, and different fruits.
Pitfalls to Watch Out For
- Gritty texture: If your blender struggles with oats or raisins, soak the raisins and pre-grind the oats. Blend longer than you think.
- Overly sweet: Raisins and banana are already sweet.
Taste before adding syrup or honey.
- Too thick to sip: Oats swell as they sit. Thin with milk and stir well before drinking leftovers.
- Using instant oatmeal packets: These can be overly fine or flavored. Stick to plain rolled oats for the best texture and taste.
- Skipping the salt: Just a pinch sharpens the flavors and keeps the sweetness balanced.
Alternatives
- Dairy-free: Use almond, oat, or soy milk and a dairy-free yogurt.
Coconut yogurt adds extra creaminess.
- No banana: Swap in 1/2 cup frozen cauliflower rice plus 2–3 dates or a bit more raisins. Or use 1/2 cup applesauce and extra ice.
- Extra protein: Add a scoop of vanilla or unflavored protein powder. You may need an extra splash of milk.
- Nutty twist: Blend in 1 tablespoon almond butter or peanut butter for a cookie-dough vibe.
- Spice it up: Add a pinch of nutmeg or cardamom.
A little goes a long way.
- Fiber boost: Stir in 1 teaspoon chia or ground flax. Let it sit 2–3 minutes to thicken, then blend again if needed.
- Lower sugar: Reduce raisins to 2 tablespoons and skip the sweetener. Use unsweetened milk and yogurt.
FAQ
Do I have to soak the raisins?
No, but soaking helps them blend smoothly and prevents any chewy bits.
If your blender is powerful, you can skip it. Using hot water for a quick 10-minute soak makes a noticeable difference.
Can I use steel-cut oats?
Not ideal here. Steel-cut oats are too hard and can stay gritty.
Rolled oats blend best and create a smooth, creamy texture.
What can I use instead of yogurt?
Use more milk and add a few ice cubes for body, or swap in a dairy-free yogurt. You can also add 1–2 tablespoons of cashews (soaked) for creaminess.
How do I make it taste more like an oatmeal cookie?
Add a tablespoon of almond butter, a touch more cinnamon, and a drop of molasses or maple syrup. A few vanilla wafers or a graham cracker blend-in makes it dessert-like, if that’s your goal.
Is this smoothie good for kids?
Yes.
It’s naturally sweet and familiar in flavor. For little ones, skip extra sweeteners and thin it slightly with milk so it’s easier to sip.
Can I make it the night before?
Yes, but expect it to thicken. Store in a sealed jar, then loosen with milk and shake well in the morning.
The flavor deepens overnight, which many people love.
What if I don’t like raisins?
Swap with dates (2–3 pitted), dried figs, or even a handful of grapes for a fresher sweetness. You may need to adjust the liquid slightly.
Will this keep me full?
Most likely. The combo of oats, yogurt, and fiber-rich fruit is designed to keep you satisfied.
For extra staying power, add protein powder or nut butter.
