My oatmeal smoothie is thick, creamy, and packed with nutrients and chocolate flavor. It’s vegan and made with NO banana!

I used to think there was no breakfast more convenient than overnight oats. That is, until I discovered you can blend oats into smoothies.
Turns out, when you blend oats with more traditional smoothie ingredients, you’re left with a thick, creamy smoothie that’s deceptively filling. I can have an oatmeal smoothie and even forget when it’s lunchtime. Now that’s saying something!

Why I love this recipe
- Great for weight loss. Oats are full of fiber, peanut butter is naturally satiating, and I even added a scoop of protein powder for good measure.
- Banana-free. I love banana smoothies, but sometimes, when I make them, I find I’m hungry 10 minutes later.
- Thickshake texture. It’s like drinking my healthy milkshake.
- Customize it however you want. I like to add superfoods or swap the nut butter, but you can modify this smoothie however you need to.
Ingredients needed
- Rolled oats. Also known as old fashioned oats, these will be blended to add fiber and thickness to the smoothie. Quick oats can also be used, but I wouldn’t recommend steel cut oats as they’re difficult to blend finely.
- Cocoa powder. Adds essential chocolate flavor plus antioxidants.
- Protein powder. Optional but highly recommended if you’d like more staying power and extra chocolate flavor.
- Sweetener. I like using agave or maple syrup, but sugar or sweeteners also work.
- Chia seeds. Optional, but it thickens the smoothie and gives it an extra boost of fiber and omega-3 fatty acids.
- Creamy peanut butter or alternative. A spoonful of peanut butter adds tons of richness and helps keep you full for longer. Alternatively, try my low calorie peanut butter or almond butter.
- Milk. To blend. I prefer unsweetened almond milk, but oat milk or any dairy-free milk works.

Arman’s recipe tips
- Taste as you go, and add any sweetener as needed.
- Thicken the smoothie. Add ice cubes or, if you don’t mind extra calories, add avocado or a dollop of Greek yogurt.
- Add a dash of cinnamon. To complement the chocolate and peanut butter flavor.
- Nut-free. Swap the peanut butter for sunflower seed butter or tahini.
Variations
- Strawberry banana oat smoothie. Omit the cocoa powder and peanut butter, and add ½ frozen banana and ½ cup of frozen strawberries.
- Tropical oat smoothie. Add ½ cup of frozen pineapple and mango.
- Green oat smoothie. Add 2-3 kale leaves and ½ of a frozen banana for extra sweetness.
Storage instructions
To store: While best enjoyed fresh, this smoothie can be stored in the fridge in a sealed container for up to 3 days. Stir it well before serving.

I needed this. I always make overnight oats or oatmeal but never smoothies like this. Wow!
Yes. I made it and it passed muster with my DH. I made it with almond butter, almond milk, and carob powder. I added 1 tsp vanilla. Next time I might consider using 1 cup of milk. But it is very flavorful Will do again this week and try with strawberries and bananas, which are stored in the freezer. Thank you.
Can I use water instead of milk?
You can!
will def try!
thanx! 😊
I added 2 big handfuls of spinach and some double strength coffee, so good.
Yummy! This smoothie looks so refreshing. I can’t wait to give this a try.i love this healthy smoothie 🥤
I’m in love with this smoothie every since my dash diet this smoothie is life due to me not eating breakfast but drink decaf coffee I stay full until 1pm and then it’s lunch time
This smoothie never fails! It’s so thick and flavorful, I really feel like I’m eating some dark chocolate dessert! And it’s healthy!?! I often skip the peanut butter for preference and half the recipe because it’s just too much food for me. Comes out amazing every time! Thank you for this perfect oatmeal smoothie recipe and introducing me to the world of oat smoothies
Instead of maple syrup, I use a banana (natural sweetener). This smoothie is delicious.
I had added a banana but did not think about eliminating the sweetener. I will do that next time.
I had also added collagen to mine.
I love adding collagen! 🙂
I just made this smoothie using peanut butter and monk sugar. So good. I never want to eat in the mornings, but now I have something to look forward to. I am going to try mixing all ingredients the night before so all I have to do is just blend.
Excellent
Have this every morning and DAYUMMMMMMMMM its as if the taste gets better and better! My whole family love it when I ask if they want some. Overall a huge 10/10. Best smoothie by far !!!
Yummy! This smoothie looks so refreshing. I can’t wait to give this a try.
Just made this with a spoon of PB2 instead of LSA mix and it was sooo delicious. Actually like batter!
I don’t think I could ever do just a smoothie for dinner. I like to eat, haha, so I think I would have to serve it up smoothie bowl style and top it with lots of texterous (not a word 😉 ) goodness. But I’m definitely not opposed to chocolate for so serve it on up!
Oatmeal makes the BEST addition to smoothies; it adds that cookie dough feel.
A former boyfriend introduced me to oatmeal smoothies/milkshakes If they didn’t remind me of him so much, I’d probably make them all the time.
I’ve had very similar smoothies before and they are amazing. Especially after a good workout. Glad you’ve found one you’re excited about, that’s so awesome!
Wait. Brownie batter that I can drink…for a meal? Sign me up for this one…like yesterday! *Queue Applause* Haha! So I am strictly a morning worker-out-er. Like you, if it doesn’t happen first thing, then it’s unlikely to happen at all. But if there is a promise of this oatmeal smoothie in there, then I might be convinced to wait until later in the day. I’m still recovering from that nasty cold, so the workout room in the basement has been mighty quiet lately…next week I’ll hit it again! But I won’t be able to wait until next week for this smoothie. That has to happen today!
