Ingredients You’ll Need
Gathering your ingredients is a breeze, and each one plays a crucial role in building the flavor, texture, and irresistible charm of this frappuccino. From the smoothness of the milk to the punch of the coffee and the heavenly peanut butter, every element is essential for that perfect sip.
- 1 cup milk (dairy or non-dairy): Provides creaminess and richness that balances the espresso and peanut butter.
- 1 cup ice: Creates that signature frappuccino chill and frothy texture.
- 1/3 cup brewed coffee (cooled) or 1 shot espresso: Adds a bold coffee kick for that authentic frappuccino flavor.
- 2 tablespoons creamy peanut butter: Delivers nutty depth and a velvety mouthfeel.
- 2 tablespoons chocolate syrup: Brings a sweet cocoa twist that perfectly complements peanut butter.

How to Make Peanut Butter Cup Frappuccino Recipe
Step 1: Combine the Ingredients
Start by pouring the milk into a blender, followed by the ice, cooled coffee or espresso, creamy peanut butter, chocolate syrup, sugar, and vanilla extract. Each ingredient layers flavors that will come together beautifully.
Step 2: Blend It All Up
Blend on high speed until everything is completely smooth and creamy. This step is crucial to achieve the frappuccino’s silky texture and ensure the peanut butter melds seamlessly with the coffee and chocolate.
Step 3: Taste and Tweak
This is the moment to sample your creation. If you feel it needs a bit more sweetness or chocolate punch, add a touch more sugar or syrup and blend briefly again. Always taste until it feels just right for your palate.
Step 4: Serve with Style
Pour your frappuccino into a tall glass. This recipe shines best when served fresh, cold, and topped with clouds of whipped cream and crushed mini peanut butter cups for that extra wow factor.
How to Serve Peanut Butter Cup Frappuccino Recipe

Garnishes
The toppings can take your Peanut Butter Cup Frappuccino Recipe from delicious to downright irresistible. A generous swirl of whipped cream complemented by chopped mini peanut butter cups brings a creamy texture and delightful crunch. A drizzle of chocolate syrup on top adds eye-catching gloss and a burst of extra flavor.
Side Dishes
This frappuccino pairs wonderfully with light treats like a buttery cookie or a chocolate chip muffin. The combination of textures and flavors elevates the entire experience without overpowering the drink’s richness.
Creative Ways to Present
For a fun twist, drizzle chocolate syrup along the inside of the glass before pouring in the frappuccino, creating beautiful swirls. Use colorful straws or sprinkle crushed peanuts on top of the whipped cream to add texture and visual appeal. Impress your guests or yourself with these little touches!
Make Ahead and Storage
Storing Leftovers
This frappuccino tastes best fresh, but if you do have leftovers, store them in an airtight container in the refrigerator for up to 24 hours. Keep in mind, the texture may separate slightly, so give it a good stir before enjoying.
Freezing
You can freeze this mixture in an ice cube tray to have ready-made frappuccino cubes. When ready, blend the cubes with a splash of milk or coffee for a quick refresher. However, freezing the fully blended drink is not recommended as it may icily harden and lose smoothness.
Reheating
Since this is an iced beverage, reheating isn’t ideal. If you prefer a warm coffee-peanut butter treat, try warming the milk and coffee separately and stir in peanut butter and chocolate syrup for a delicious hot mocha-inspired drink.
FAQs
Can I make this Peanut Butter Cup Frappuccino Recipe without coffee?
Absolutely! For a kid-friendly or caffeine-free version, simply omit the coffee. The peanut butter and chocolate syrup will still provide plenty of rich flavor and sweetness.
What kind of peanut butter works best?
Creamy peanut butter blends smoothly and delivers the right texture. Natural or chunky varieties can be used, but you may need to blend a bit longer to avoid lumps.
Can I use a sugar substitute?
Yes, feel free to use your preferred sweetener such as stevia, erythritol, or maple syrup. Adjust the amounts to taste as some substitutes are sweeter than sugar.
Is it possible to make this vegan?
Definitely! Use non-dairy milk like almond or oat milk, ensure your chocolate syrup is dairy-free, and top with coconut whipped cream to keep your frappuccino plant-based and delicious.
How do I get a thicker frappuccino?
Add more ice or toss in a scoop of vanilla ice cream before blending. Both tricks enhance the creaminess and create that classic frappuccino density.
