Ingredients You’ll Need
The magic behind this smoothie lies in a small handful of humble ingredients that are probably your pantry staples. Each one brings something special—richness, sweetness, creaminess, or that unmistakable chocolate-peanut butter flavor combo.
- Frozen banana: The secret to a creamy, ice-cream-like texture and natural sweetness that ties the smoothie together.
- Peanut butter: Gives that classic nutty flavor and irresistible richness—choose creamy for a silky finish or crunchy for added bite.
- Unsweetened cocoa powder: Real chocolate flavor with no extra sugar, making the smoothie taste like a decadent treat.
- Milk (dairy or non-dairy): Use your go-to milk for just the right amount of liquid, whether you love dairy, almond, oat, or soy.
- Plain or vanilla Greek yogurt: Adds thick, luscious body and a noticeable boost of protein to keep you satisfied longer.
- Honey or maple syrup (optional): A natural touch of extra sweetness—add if you want your Peanut Butter Cup Smoothie a little more dessert-like.
- Vanilla extract: Enhances all the other flavors and gives depth, just like in your favorite baked goods.
- Ice cubes: Chills and thickens the smoothie, making it frosty and refreshing.
- Pinch of salt (optional): Balances sweetness and brings out the rich chocolate and peanut butter notes—like a salted chocolate bar!
How to Make Peanut Butter Cup Smoothie
Step 1: Gather and Prep Ingredients
Start by making sure you have everything ready. Slice and freeze your banana the night before for the thickest, creamiest texture, but if you forgot, you can use a fresh one with a bit more ice. Measure out your peanut butter, cocoa powder, and yogurt so everything is ready to go when you’re blending.
Step 2: Add Everything to the Blender
Into your blender goes the frozen banana, peanut butter, cocoa powder, milk, Greek yogurt, sweetener (if using), vanilla extract, ice cubes, and a tiny pinch of salt if you want to balance out the sweeter flavors. Tossing everything in at once guarantees an even, super-smooth blend.
Step 3: Blend Until Ultra Smooth
Secure the lid and blend everything on high for about 30 to 60 seconds, stopping to scrape down the sides if needed. The Peanut Butter Cup Smoothie should look thick and creamy, with no big chunks of banana or ice left. If you want it even thicker, add a few more ice cubes or a touch less milk.
Step 4: Taste and Tweak
Give your smoothie a quick taste. Need more sweetness? Add another drizzle of honey or maple syrup. Want it more chocolatey? A bit more cocoa powder does the trick. Adjust as you like—this recipe is super flexible!
Step 5: Serve and Enjoy Immediately
Pour your Peanut Butter Cup Smoothie into a tall glass, and dive in with your favorite reusable straw. If you’re feeling fancy, don’t forget the fun garnishes suggested below.
How to Serve Peanut Butter Cup Smoothie

Garnishes
The finishing touches can turn a simple smoothie into something special. I love sprinkling mini chocolate chips or chopped peanuts on top for crunch and that candy bar vibe. A swirl of whipped cream, a drizzle of melted peanut butter, or a few cacao nibs take it right over the top. Go as simple or as fancy as you like—there are no wrong answers here!
Side Dishes
This smoothie is often satisfying enough for breakfast on its own, but it plays well with others. Pair it with a fruit salad for extra freshness, a toasted English muffin, or a homemade granola bar. If you’re sipping it as a snack, a crisp apple or celery sticks with more peanut butter keep the fun going.
Creative Ways to Present
Bring out your inner chef by serving your Peanut Butter Cup Smoothie in mason jars layered with sliced bananas or a chocolate drizzle. For a brunch crowd, line up mini glasses as smoothie “shooters” with a chocolate-peanut rim. For kids, pop it into freezer molds for creamy smoothie pops—they’ll think it’s the best summer treat ever!
Make Ahead and Storage
Storing Leftovers
If you have extra smoothie left over (which rarely happens in my house!), pour it into an airtight container and refrigerate. It’ll keep for up to 24 hours, though you may need to give it a good stir or shake, as some separation is normal with homemade smoothies.
Freezing
You can absolutely freeze your Peanut Butter Cup Smoothie for later. Pour it into an ice cube tray, let it freeze, then transfer the cubes to a freezer bag. Blend the cubes with a splash of milk when you’re ready for your next treat, or enjoy the cubes as little frosty bites straight from the freezer.
Reheating
While you probably won’t want to heat your smoothie, if it’s too hard from the freezer or you prefer a thinner texture, simply let it sit at room temperature for 10 to 15 minutes. Give it a good stir or quick blend to restore its creamy consistency.
FAQs
Can I make this Peanut Butter Cup Smoothie vegan?
Yes! Use a plant-based milk like almond, oat, or soy, and opt for coconut or non-dairy yogurt instead of Greek yogurt. Swap honey for maple syrup, and you’re good to go.
Is there a way to make it higher in protein?
Definitely. A scoop of your favorite chocolate or vanilla protein powder blends perfectly in, or you can add extra Greek yogurt for more protein and an even thicker texture.
What can I use instead of banana?
If banana isn’t your jam, try using frozen cauliflower for a creamy base without the strong flavor, or frozen avocado for a rich, luscious texture. You might want a bit more sweetener when swapping out the banana.
Do I need a high-powered blender?
While a high-powered blender makes things super creamy, you can still make a great Peanut Butter Cup Smoothie with a standard blender. Just make sure your banana is sliced before freezing and chop up any frozen ingredients for easier blending.
Can I prep the ingredients ahead to save time?
Absolutely! Portion out the dry ingredients (cocoa powder, salt) and keep them in little jars or baggies. Freeze your banana slices ahead and store measured yogurt scoops in the fridge for a few days—it’ll make morning smoothie assembly a breeze.
Final Thoughts
This Peanut Butter Cup Smoothie is as delicious as it is easy, and I can’t recommend it enough for chocolate and peanut butter lovers. With just a blender and a few minutes, you’ll have a treat that’s equal parts nourishing and nostalgic. Give it a try—you’ll be shocked by how often you’re craving a sip!
