Blueberry Banana Oatmeal Smoothie has totally saved my mornings more times than I can count. Let me guess: you’re sick of empty-calorie breakfasts, you want something fast, and your taste buds? Yeah, they’re bored. Trust me, I’ve been there, feasting on sad toast before work. Lucky for us both, this smoothie is not only quick but crazy good for you and just happens to taste like dessert. I swear I don’t even miss bagels now.
Why You’ll Love This Smoothie
Honestly, I could write sonnets about this Blueberry Banana Oatmeal Smoothie. It checks all the boxes. The first sip is creamy and cold, with blueberry tang and banana sweetness—so it actually feels like a treat, not a chore. You get real oats in there, which means you’ll actually stay full until lunch (hallelujah). Oh, and everything just gets tossed in the blender. Zero fuss. If you’re new to smoothies and worried if it’ll fill you up or just taste weird, relax! I’ve had picky eaters ask for seconds. Plus, you can sneak in extras, like spinach or protein powder, and not one person will notice. Even on my laziest days, this blend never lets me down.
I swear, this smoothie made my 8am video calls almost enjoyable. Feels like I’m getting away with something delicious and healthy!

How to Make Blueberry Banana Oatmeal Smoothie
Let’s break it down—no fancy stuff. You just need a blender, five minutes, and these ingredients hanging out in your kitchen:
- 1 ripe banana, fresh or frozen (honestly, whatever’s about to go brown works best)
- 3/4 cup frozen blueberries (I use wild ones if I’m feeling fancy)
- 1/4 cup old-fashioned rolled oats (not the super-quick kind, trust me)
- 1 cup milk (dairy, almond, oat, mood depending)
- 1 tablespoon honey or maple syrup (optional, but dreamy if your banana isn’t super sweet)
- Handful of ice cubes (if you want it extra cold)
Toss everything in your blender. Blast it until smooth. Pour it into your favorite glass (okay, my old jam jar) and that’s literally it. If it’s too thick, splash in some extra milk. Too thin? Add more oats or ice. Smoothie crises don’t have to exist.
Nutrition Facts (per serving)
For something so easy, the Blueberry Banana Oatmeal Smoothie packs a nutritional punch. You’re looking at a good hit of fiber from the oats and fruit—makes you regular, no lie. Each glass kicks in potassium, vitamin C, and antioxidants (thanks blueberries!) so you feel like a total health wizard. Usually about 215-240 calories, if you go easy on sweeteners and stick with regular milk or a plain non-dairy kind. There’s a bit of protein and iron too—not steak dinner levels, but enough to give you staying power. Just a heads-up, if you add nut butter, it jumps up a few notches in the filling department.
Kids will drink one and not realize they just ate oatmeal for breakfast. That’s a win in my book.
Recipe Notes
I’ll be real: my first Blueberry Banana Oatmeal Smoothie was lumpy. If that happens to you, just blend a little longer—your old banana could use some help breaking down. Sometimes I swap half the blueberries for strawberries if that’s what’s around. Oh—and if you wanna go full morning-hero, sprinkle cinnamon or vanilla before blending. It makes your kitchen smell like a five-star restaurant.
Some mornings, I prep smoothie bags (ingredients in a bag in the freezer) at the start of the week. Just dump one in with milk, blend, and you’re golden. Be warned: oat milk makes it extra creamy but regular milk or soy work, too. You seriously can’t mess it up (unless you use steel cut oats—don’t ask, trust me).
- Double the recipe for a two-person quick breakfast.
- Pour leftovers into popsicle molds for a snack.
- Add a scoop of yogurt for tangy thickness.
- Sprinkle flax or chia if you’re feeling “superfood-y.”
Don’t stress over exact measurements—this is one recipe you can just eyeball.
More Easy Smoothie Recipes You’ll Love
If you’re on the smoothie train now (and I hope you are), you seriously have to try a few other blends. Peanut butter chocolate is my afternoon pick-me-up, if you’ve got a sweet tooth. Strawberry spinach gets some veggies in with zero salad vibes. Or mix mango with pineapple and coconut milk for a total vacation-in-a-glass scenario.
The best part? Each one starts with the same simple rules—toss, blend, sip, repeat. Lazy mornings may never look the same again.
And hey, if today’s breakfast gets you excited, next week’s lineup just got way easier.
Common Questions
Can I use regular oats or do they have to be quick?
Old-fashioned rolled oats blend smoother and give the best texture. Quick oats can work in a pinch, just might be a teensy bit mushier.
Can this smoothie be made ahead?
Sure can! Sometimes I make mine at night and give it a shake in the morning. If it thickens up, just splash in more milk and give it a good stir.
Is this smoothie super sweet?
Not really—if you use a ripe banana, most folks find it sweet enough. If you’ve got a major sweet tooth, drizzle in a little honey or maple syrup.
Will kids like it or is it too “healthy”?
Honestly? My niece licked the cup clean last time she visited. They’ll never taste the oats if you blend long enough.
Can I add protein powder or nut butter to this?
Totally! I do it when I know I’ll skip lunch. It bulks it up but still tastes amazing.
Your Breakfast Just Got Upleveled
Here’s the deal: With the Blueberry Banana Oatmeal Smoothie, busy breakfasts seriously don’t have to be boring or stressful. You get fiber, fruit, and something actually filling.
