How to Make

Quick Overview

This frappuccino is quick to prepare, creamy in texture, and richly flavored. It blends cold coffee with milk, peanut butter, and chocolate into an icy treat in about 5 to 10 minutes. The standout element is the creamy peanut butter swirl that pairs perfectly with chocolate drizzle.

Prep and cook time: 5 minutes active, 0–5 minutes cooling time for brewed coffee if needed.

Ingredients

1 cup brewed coffee, cooled completely (room temperature or chilled)
1 cup milk, dairy or non-dairy (almond, oat, or whole milk recommended)
2 tablespoons peanut butter, creamy and at room temperature
2 tablespoons chocolate syrup (plus extra for garnish)
1–2 tablespoons sugar or sweetener (optional; adjust to taste)
1 cup ice (crushed or cubed)
Whipped cream for topping (store-bought or freshly whipped)
Chocolate and peanut butter drizzle for garnish (melt a little peanut butter or use extra syrup)

Directions

Prepare the Coffee: Brew 1 cup of your preferred coffee and allow it to cool completely. For best flavor, brew slightly stronger than usual so the coffee flavor stands up to the milk and ice. Chill in the fridge for 5–10 minutes if needed.
Blend Ingredients: In a blender, add the cooled coffee, 1 cup milk, 2 tablespoons creamy peanut butter, 2 tablespoons chocolate syrup, and 1–2 tablespoons sugar or sweetener if desired. Start on low speed to combine.
Add Ice: Add 1 cup of ice to the blender. Increase speed to high and blend in 15–30 second bursts until the mixture is smooth, thick, and frothy. If too thin, add a few more ice cubes and blend again; if too thick, add a splash of milk.
Adjust Flavor: Taste a small spoonful and adjust sweetness or peanut butter intensity. Add more sweetener or another half tablespoon of peanut butter if you want a bolder nutty flavor.
Serve: Pour the frappuccino into glasses. Top generously with whipped cream, then drizzle chocolate syrup and a thin stream of melted peanut butter over the top for a decadent finish.
Enjoy: Serve immediately for the best texture and flavor — frappuccinos are at their peak right after blending.

What to Serve With

Sweet pairings: Chocolate chip cookies, peanut-butter sandwich cookies, or a slice of banana bread for a classic combo.
Savory contrast: A small cheese plate or buttered whole-grain toast to balance sweetness.
Light snacks: Fresh fruit like apple slices or strawberries to add brightness and cut through the richness.
Brunch idea: Pair with scrambled eggs or savory muffins to turn this into a more complete weekend brunch menu.

Top Tips for Perfecting

Peanut butter choice: Use creamy peanut butter for a smooth texture; natural peanut butter can separate, so stir well before measuring. For a nuttier flavor, try almond butter, but expect a different taste profile.
Milk swaps: Oat milk gives a creamier, richer feel; almond milk is lighter. Full-fat milk yields the creamiest texture.
Coffee intensity: Use a strong brew or a double-strength espresso shot if you prefer pronounced coffee notes.
Texture control: For a thicker frappuccino, reduce the coffee slightly or add more ice; for milkshake-like consistency, add a scoop of vanilla ice cream.
Avoid over-blending: Blend just until smooth; over-blending warms the mixture slightly and can dilute froth.
For kids: Omit coffee and replace with cold chocolate milk for a kid-friendly peanut butter chocolate shake — see our tips and a similar dessert-style approach in the chewy peanut butter brownies article for more peanut-butter pairing ideas.

Storing and Reheating Tips

Refrigeration: This drink is best enjoyed fresh. If you have leftovers, store in an airtight container in the refrigerator for up to 24 hours. Expect some separation; stir or re-blend briefly to refresh texture.
Freezing: You can freeze the blended mixture in ice cube trays for future quick frappes. Freeze for up to 1 month. Blend frozen cubes with a splash of milk to revive.
Reheating: Not recommended — reheating will ruin the frappuccino texture and melt the froth. If you need a warm peanut-butter coffee, prepare a fresh hot version by stirring peanut butter and chocolate syrup into hot brewed coffee.

FAQs

Can I make this without coffee?
Yes. Replace the brewed coffee with cold chocolate milk or chilled decaf coffee for a caffeine-free but still delicious treat.

Can I use crunchy peanut butter?
You can, but the blender will chop the nuts and add texture. For the smoothest frappuccino, use creamy peanut butter.

How can I make it less sweet?
Reduce or omit the added sugar and use unsweetened chocolate syrup, or choose a lower-sugar peanut butter. Taste and adjust gradually.

Is this suitable for kids?
If made with decaf coffee or chocolate milk instead of brewed coffee, it becomes kid-friendly and still tasty.

Can I make a large batch for parties?
Yes. Multiply ingredients and blend in batches for the best texture. Keep blended portions cold and serve immediately.
