Ingredients You’ll Need 🛒

Before you hit the blender, let’s gather the essentials. Most of these are everyday ingredients, making it easy to whip up this recipe anytime a craving strikes.

1 cup strongly brewed coffee, chilled
(Medium roast is ideal for balance, but dark roast works for extra bold flavor.)
1 cup milk of choice
(Dairy, almond, oat, or soy all work beautifully.)
2 tablespoons creamy peanut butter
(For a lower-fat version, substitute with 3 tablespoons PB2 powder mixed with 1 tbsp water.)
2 tablespoons chocolate syrup
(Plus extra for that irresistible drizzle on top.)
1–2 tablespoons sugar or sweetener
(Adjust to taste. Maple syrup or stevia work as alternatives.)
1 cup crushed ice
(Crushing the ice before blending results in a smoother texture.)
Optional: ⅛ teaspoon xanthan gum
(Creates that thick, creamy, café-like mouthfeel.)
Whipped cream, for topping
(Because… obviously.)
Optional garnish:
- Light dusting of cocoa powder
- Crushed peanut butter cups or mini Reese’s Pieces for an extra treat

Step-by-Step Instructions 👩‍🍳

1. Chill & Prep Everything

Make sure your coffee is completely chilled before starting. Hot coffee will melt the ice and result in a runny frappuccino. You can brew it the night before and store it in the fridge, or make a quick batch and chill it over ice.

Pro Tip: If you have leftover coffee from the morning, don’t toss it—frappuccino time! Crush your ice ahead of time to help the blender create that super-smooth frozen texture.

2. Blend the Base Ingredients

In a high-powered blender, combine:

1 cup chilled coffee
1 cup milk
2 tablespoons peanut butter (or PB2 mix)
2 tablespoons chocolate syrup
1–2 tablespoons sugar or sweetener

Blend on low speed for 10 seconds to bring everything together. At this stage, you’re forming the flavorful foundation.

3. Add Ice & Optional Xanthan Gum

Now toss in your 1 cup of crushed ice and (if using) ⅛ teaspoon xanthan gum. This little ingredient makes a big difference—it emulsifies the mixture, so it doesn’t separate and creates that ultra-smooth frappuccino texture we all know and love.

Blend everything on high for 20–30 seconds, or until the consistency is thick, creamy, and frothy—like a frozen milkshake with a caffeinated kick.

4. Taste Test & Customize

Give it a taste!

Want it richer? Add another ½ tablespoon of peanut butter.
Craving more sweetness or chocolate? Toss in an extra splash of syrup.
Need a bit more chill? Add a few extra ice cubes and blend again.

5. Serve, Garnish & Sip!

Pour your frappuccino into a tall glass. Top generously with whipped cream. Now comes the fun part—drizzle extra chocolate syrup over the top, dust with cocoa powder, or sprinkle on some crushed peanut butter cups for extra flair.

Snap a photo for Instagram, take a deep breath, and sip slowly—this is your moment of frozen, peanut-buttery joy.

Tips for the Perfect Peanut Butter Frappuccino Every Time ☕️

Use quality coffee: A medium roast with nutty undertones complements the peanut butter perfectly.
Peanut butter matters: Creamy peanut butter blends better than chunky. Natural PB can work but may separate slightly.
Want a thicker texture? Add more ice or a few frozen banana slices (bonus flavor!).
Need it dairy-free? Use almond, oat, or soy milk and opt for dairy-free whipped topping.
Low sugar option? Use a sugar substitute and PB2 powder instead of full-fat peanut butter.

Healthier Swaps & Dietary Tweaks 🥄

Vegan	Dairy milk + whipped cream	Plant-based versions
