Reese’s Peanut Butter Frappuccino

I’ll never forget the sunny day when I cleared out the pantry, I unearthed a jar of peanut butter and a bag of Reese’s Pieces I hadn’t seen in ages. The idea sparked instantly. A craving hit—something sweet, something cold, and definitely something caffeinated.

I didn’t want to settle for a plain iced coffee or a sugar bomb milkshake. I wanted that creamy, nutty flavor of peanut butter to meet the bold richness of coffee, with a little chocolate magic swirled in.

So I went to the blender, threw in the essentials, and gave it a whirl. What poured out was better than expected: a thick, frosty drink that felt like dessert but perked me up like my morning brew. It reminded me of those specialty drinks from coffee shops—except this one wasn’t $6 and didn’t require me to leave the house.

Now, whenever I want something indulgent but easy to whip up, this frappuccino is my go-to. It’s just the right mix of comfort, caffeine, and chocolatey fun—kind of like a milkshake and a mocha had a peanut buttery baby.

Short Description

This homemade Reese’s Peanut Butter Frappuccino blends bold coffee, creamy peanut butter, and sweet chocolate for a refreshing treat that’s both energizing and indulgent.

Key Ingredients

• 1 cup brewed coffee, cooled
• 1 cup milk (dairy, almond, oat, etc.)
• 2 tablespoons creamy peanut butter
• 2 tablespoons sugar (optional, or to taste)
• 1 cup ice cubes
• Whipped cream, for topping (optional)
• Chocolate syrup or crushed Reese’s Pieces

Tools Needed

• Blender
• Coffee maker (drip, French press, or any preferred method)
• Tall glass
• Straw and spoon

Cooking Instructions

Step 1: Brew and Cool the Coffee
Make 1 cup of strong coffee using your favorite brewing method. Let it cool to room temperature. To speed things up, pop it in the fridge or stir in a few ice cubes.

Step 2: Blend the Base
Add the cooled coffee, milk, peanut butter, and sugar (if using) to your blender. Blend on high until smooth and creamy—about 30 seconds.

Step 3: Add the Ice
Toss in the ice cubes and blend again. The goal is a thick, slushy-like texture. If it’s too thick, add a splash of milk and pulse until you get the right consistency.

Step 4: Pour and Garnish
Pour into a tall glass. Top with whipped cream, drizzle chocolate syrup over the top, and sprinkle crushed Reese’s Pieces if you want an extra treat.

Mistakes to Avoid & Solutions

Mistake 1: Using hot coffee in the blender
Solution: Always cool your coffee first, or it will melt the ice and thin out your drink.

Mistake 2: Adding too much peanut butter
Solution: Stick to 2 tablespoons—too much can overpower the coffee and create a sticky texture.

Mistake 3: Overblending the ice
Solution: Blend just until smooth and icy. Overblending can make it watery.

Mistake 4: Forgetting to adjust sweetness
Solution: Taste after blending the base. Add more sugar if needed and pulse again.

Mistake 5: Using chunky peanut butter
Solution: Creamy peanut butter works best for smoothness and even blending.

Serving and Pairing Suggestions

– Serve in a tall glass with a straw and spoon for that coffeehouse feel.

Storage and Reheating Tips

Refrigerate leftovers in an airtight jar for up to 1 day, but expect separation.

To reblend: Shake or stir well before drinking. For best results, add a few ice cubes and blend again before serving.

Do not freeze: The texture changes and becomes icy-solid. Best enjoyed fresh.

FAQs

1. Can I use instant coffee instead of brewed coffee?
Yes, dissolve 1–2 teaspoons of instant coffee in 1 cup of cold water as a quick substitute.

Add 1 tablespoon of cocoa powder or a squirt of chocolate syrup during blending.

If made with decaf and less sugar, yes! It’s a fun treat for kids who love Reese’s flavors.
