How to Make

Quick Overview

This frappuccino is quick, easy, and deeply satisfying. It blends cool, brewed coffee with creamy peanut butter and chocolate syrup, producing a silky texture with a frosty finish. The standout element is the peanut butter: it adds body and a nutty richness that transforms a simple coffee drink into a dessert-like treat. Total time: about 10 minutes (5 minutes prep, 5 minutes blending and serving).

Ingredients

• 1 cup brewed coffee, cooled completely
• 1 cup milk, dairy or non-dairy (room temperature is fine)
• 2 tablespoons peanut butter, smooth or natural (if using natural, stir before measuring)
• 2 tablespoons chocolate syrup (plus extra for drizzling)
• 1–2 tablespoons sugar or sweetener, optional (adjust to taste)
• 1 cup ice
• Whipped cream for topping (as desired)
• Chocolate and peanut butter drizzle for garnish (melted chocolate or extra syrup; warmed peanut butter thinned slightly for drizzling)

Directions

1. Prepare the Coffee: Brew 1 cup of coffee and allow it to cool completely. For best flavor, use a bold or medium-dark roast. You can chill it in the fridge for 10–15 minutes to speed things up.
2. Blend Ingredients: In a blender, combine the cooled coffee, 1 cup milk, 2 tablespoons peanut butter, 2 tablespoons chocolate syrup, and 1–2 tablespoons sugar or sweetener if you like it sweeter. Start on low speed to combine.
3. Add Ice: Add 1 cup ice to the blender. Increase speed and blend until the mixture is smooth and creamy with no large ice chunks, about 30–45 seconds depending on your blender.
4. Adjust Flavor: Taste and adjust sweetness or peanut butter amount if needed. If it’s too thin, add a few more ice cubes and blend briefly. If you want more peanut flavor, add another half tablespoon of peanut butter and blend again.
5. Serve: Pour the frappuccino into tall glasses. Top with a generous swirl of whipped cream, then drizzle chocolate syrup and a thin stream of warmed peanut butter on top for visual flair and extra flavor.
6. Enjoy: Serve immediately for the best flavor and texture — the frosty, creamy consistency is at its peak right away.

What to Serve With

• Classic pairings: A warm chocolate chip cookie or a peanut butter cookie complements the cold drink perfectly.
• Brunch ideas: Serve alongside scrambled eggs and bacon for a sweet-and-savory weekend brunch contrast.
• Light snacks: Fresh fruit slices or a small bowl of mixed nuts balance the richness and add texture.
• Dessert duo: Pair with a small square of dark chocolate or a mini brownie for a true dessert experience.

Top Tips for Perfecting

• Ingredient substitutions: Use almond or oat milk for a dairy-free option; use a natural peanut butter for a more pronounced nutty flavor but stir well to avoid separation.
• Sweetness control: Start with 1 tablespoon of sugar, then add more to taste. The toppings add extra sweetness, so keep that in mind.
• Texture tricks: For an extra thick frappuccino, freeze your milk in ice cube trays and use those cubes in place of some of the ice.
• Flavor boosts: Add a pinch of sea salt to enhance the chocolate and peanut butter notes, or stir in a dash of vanilla extract for depth.
• Common mistakes to avoid: Don’t use hot coffee or you’ll melt the ice and end up with a watery drink. Also, blend long enough to smooth out peanut butter, especially if it’s natural and thicker.

Storing and Reheating Tips

• Refrigeration: This drink is best fresh. If you have leftovers, store in an airtight container in the fridge for up to 24 hours. Expect some separation; stir well before drinking.
• Freezing: You can freeze the blended mixture in ice cube trays and re-blend later for another quick frappuccino — keep frozen cubes up to 1 month.
• Shelf life: Because it contains dairy and coffee, consume within 24 hours for best taste and food safety.
• Re-serving: If refrigerated, you can re-blend leftovers with a few fresh ice cubes to restore the frosty texture.

FAQs

Can I use instant coffee instead of brewed coffee?
Yes. Dissolve 1–2 teaspoons of instant coffee in 1 cup of cold water and use that in place of brewed coffee. Taste and adjust concentration to your preference.

Is natural peanut butter okay to use?
Absolutely. Natural peanut butter works well but stir it thoroughly before measuring because oil separation is common. You may need a moment longer in the blender to fully incorporate it.

Can I make this vegan?
Yes. Use plant-based milk (oat, almond, soy) and a vegan whipped topping. Ensure the chocolate syrup and peanut butter contain no dairy additives.

How can I make it less sweet?
Omit the added sugar and reduce the chocolate syrup slightly. You can also use unsweetened cocoa powder blended with a touch of sweetener to control sweetness more precisely.

Can I add protein powder?
Yes. Add a scoop of vanilla or chocolate protein powder for a post-workout treat. You may need to increase the liquid slightly to keep the drink smooth.
