What Ingredients are in Peanut Butter Banana Oatmeal Smoothie?
This smoothie keeps things pretty simple with ingredients you probably already have hanging around your kitchen, which is honestly one of my favorite things about it.
- 1 banana
- ¼ cup peanut butter
- ⅓ cup quick oats
- ½ cup milk
- ½ cup vanilla Greek yogurt
- ½ teaspoon cinnamon
- 1 tablespoon honey
- Ice cubes (optional)
You can swap the milk for whatever you like, whether that’s almond, oat, or regular dairy, and the peanut butter can easily become almond butter if that’s more your thing, though I find peanut butter has that nostalgic punch that makes this feel like a liquid peanut butter sandwich in the best way possible.
How to Make this Peanut Butter Banana Oatmeal Smoothie
Step 1
Toss ⅓ cup quick oats into your blender and pulse them a few times until they’re finely ground, almost like flour. This is honestly the secret to avoiding that weird grainy texture that can sometimes make smoothies feel like you’re drinking breakfast cereal straight from the bowl, which isn’t exactly the vibe we’re going for here.
Step 2: Add Your Banana
Break up 1 banana into chunks and drop them into the blender with your ground oats. If you’ve got a frozen banana sitting in your freezer, even better, because it’ll make your smoothie thick and frosty without needing to load it up with ice cubes that can water everything down.
Step 3: Scoop in the Peanut Butter
Measure out ¼ cup peanut butter and add it to the blender, and yes, I know it’s going to stick to your measuring cup like it has a personal vendetta against you. The creamy kind works best here since natural peanut butter can sometimes separate and make things a bit oily, though you can absolutely use it if that’s what you’ve got.
Step 4: Pour in Your Liquids
Add ½ cup milk and ½ cup vanilla Greek yogurt to the mix, which is what’s going to give you that smooth, drinkable consistency instead of a thick sludge. The yogurt adds protein and a subtle tang that balances out all the sweetness, plus it makes the whole thing feel a bit more like an actual meal than just flavored sugar water.
Step 5: Add Your Flavor Boosters
Sprinkle in ½ teaspoon cinnamon and drizzle in 1 tablespoon honey, which might seem like small amounts but they really do round out the flavor profile. The cinnamon gives it that warm, cozy feeling, and the honey adds just enough sweetness without making it taste like a milkshake, though let’s be honest, if it did taste like a milkshake, would that really be so terrible?
Step 6: Throw in Some Ice (Maybe)
If you didn’t use a frozen banana, toss in a handful of ice cubes to get that cold, thick texture. If you did use frozen banana, you can probably skip this step entirely since your smoothie will already be plenty frosty.
Step 7: Blend Until Smooth
Run your blender on high for 30 to 60 seconds, stopping once everything is completely smooth and there are no chunks of banana or streaks of peanut butter swirling around. You want it uniform and creamy, the kind of consistency that pours easily but still feels substantial enough to keep you full.
Step 8: Pour and Enjoy Immediately
Transfer your smoothie into a glass and drink it right away while it’s still cold and perfectly blended. Smoothies are honestly best when they’re fresh since they can start to separate or get weirdly thick if they sit around too long, plus who wants to wait when you’ve got a delicious peanut butter banana situation happening right in front of you? If you’re meal prepping smoothies for the week, consider pouring the mixture into silicone muffin pans and freezing them as individual portions that you can pop out and blend fresh each morning.
What to Serve with Peanut Butter Banana Oatmeal Smoothie
This smoothie is thick enough to count as actual breakfast, so you don’t need much alongside it, though a handful of granola on top adds a nice crunch if you’re into that whole texture contrast thing.
Fresh berries like strawberries or blueberries make a solid pairing, either mixed into the smoothie or served on the side for a little extra freshness.
If you’re really hungry, a piece of whole grain toast with almond butter or a simple egg scramble works great since this is naturally a breakfast or snack situation.
Some people like to pour it into a bowl and eat it with a spoon like a smoothie bowl, which honestly just makes you feel fancier without doing any extra work.

Leftovers and Storage for this Peanut Butter Banana Oatmeal Smoothie
This smoothie is honestly best enjoyed right after you make it, when everything’s fresh and perfectly blended. But life happens, and if you need to save some for later, store it in an airtight container or mason jar in the fridge for up to 24 hours max.
Fair warning though, the oats will keep absorbing liquid as it sits, so your smooth, drinkable breakfast might turn into something closer to overnight oats consistency. Not terrible, just different. Give it a good shake or quick re-blend before drinking.
Freezer option: Pour leftovers into ice cube trays or freezer-safe jars, leaving room for expansion. Freeze up to 3 months. Thaw overnight in the fridge and blend with a splash of milk to bring it back to life.

It’s perfect for those chaotic weekday mornings when sitting down for breakfast feels like a luxury you can’t afford, or when you need something quick before hitting the gym. Honestly, anything that lets me drink my breakfast while getting ready is a win in my book.
Plus, knowing that it only takes a minute to blend together means there’s really no excuse to skip the most important meal of the day, even when you’re running on five hours of sleep and questionable life choices.
