Peanut Butter Cup White Russian combines a canned White Russian, peanut butter, dark chocolate syrup, decaf espresso, and marshmallow in a rich dessert-style cocktail with coffee and chocolate flavors. The peanut butter gives the drink a nutty finish, while the espresso keeps the sweetness from feeling too heavy.

What I like about this cocktail is how much it leans into familiar candy flavors without becoming complicated. Chocolate and peanut butter already make a classic pairing, and the creamy White Russian base gives them an easy place to come together. The espresso adds a roasted note that helps the whole drink feel more complete.

This is a great choice for Halloween parties, dessert nights, movie marathons, or any gathering where you want a playful coffee cocktail. The marshmallow web garnish gives it a spooky look that fits especially well around Halloween.

Ingredients

Each ingredient contributes to the drink’s creamy, nutty, chocolate, or coffee profile.

1 can Cutwater White Russian
1 large spoonful of peanut butter
1 oz dark chocolate syrup
Double shot of freshly brewed decaf espresso
2 marshmallows

The Cutwater White Russian provides the creamy cocktail base.

Peanut butter adds richness and a strong nutty flavor.

Dark chocolate syrup brings cocoa flavor and extra sweetness.

Decaf espresso adds coffee flavor without as much caffeine.

The marshmallows create the decorative web garnish.

Suggested Liquor Brands and Substitutions

The original recipe uses a canned White Russian, which keeps the drink simple.

Cutwater White Russian: The original base used in the recipe.
Homemade White Russian: You can use vodka, coffee liqueur, and cream if you prefer to build the base yourself.
Creamy coffee cocktail: Another ready-to-drink coffee cocktail can work, though sweetness may vary.
Smooth peanut butter: This mixes more easily than chunky peanut butter.
Chocolate sauce: This can replace dark chocolate syrup if needed.
Cold brew concentrate: Use this instead of espresso if you want an easier coffee option.

If you use a sweeter chocolate syrup, you may want to keep the peanut butter portion moderate so the drink does not become too rich.

Equipment and Glassware

This cocktail uses simple tools, plus a microwave-safe bowl for the garnish.

A martini glass works well because the wide rim gives you more room for the marshmallow web.

A coupe can also work if you prefer a rounder shape.

How to Make It

The Peanut Butter Cup White Russian starts with a warm espresso mixture, then gets shaken with the creamy cocktail base.

Brew a double shot of decaf espresso and add in one large spoonful of peanut butter-stir until melted.
Add dark chocolate syrup, and half a can of Cutwater White Russian.
Shake vigorously with ice and strain into a martini glass.
Melt your marshmallows in a microwave safe bowl for 30 seconds. Using gloves, carefully stretch and spread the marshmallow over half the glass for a webbing effect.

Let the marshmallow cool slightly before handling. Melted marshmallow can be extremely hot and sticky, so use caution when stretching it over the glass.

Serve immediately while the drink is cold and the garnish still has its web-like shape.

Pro Tips

A few small details can help the Peanut Butter Cup White Russian come out smoother and easier to serve.

Use smooth peanut butter. It melts more evenly into the espresso.
Stir while the espresso is hot. The heat helps the peanut butter dissolve.
Let the espresso mixture cool slightly. This keeps the shaker ice from melting too quickly.
Shake hard. Peanut butter and chocolate syrup need a firm shake to blend into the creamy base.
Use fresh ice. It chills the cocktail more efficiently.
Melt the marshmallow carefully. It can become dangerously hot.
Wear gloves when stretching the marshmallow. This protects your hands from the sticky mixture.
Serve right away. The marshmallow web looks best when fresh.

If the marshmallow becomes too firm to stretch, warm it again very briefly and handle it carefully.

Variations

The Peanut Butter Cup White Russian is easy to adjust while keeping the same dessert-cocktail direction.

Mocha Version: Add a little extra dark chocolate syrup.
Salted Version: Add a tiny pinch of sea salt to sharpen the chocolate and peanut butter.
Hazelnut Version: Replace some of the peanut butter with hazelnut spread.
Cold Brew Version: Use cold brew concentrate instead of espresso.
No-Web Version: Skip the marshmallow garnish for a faster, simpler presentation.

You can also drizzle a little chocolate inside the glass before straining the cocktail for an extra dessert look.

When to Serve and Pairings

The Peanut Butter Cup White Russian works especially well as an after-dinner cocktail.

It is a good choice for:

Halloween parties
Dessert nights
Movie marathons
Fall gatherings
Weekend cocktails
Coffee-themed parties

For food, pair it with desserts and snacks that work well with peanut butter, coffee, and chocolate.

Try it with:

Brownies
Chocolate cake
Peanut butter cookies
Cheesecake
Pretzels
Roasted peanuts
Chocolate truffles

It also fits nicely next to drinks such as Mocha White Russian, Baileys White Russian Cocktail, or Marshmallow Web Chocolate Cocktail.

I especially like this one with salty pretzels because the salt helps cut through the rich peanut butter, chocolate, and cream.

Storage and Serving Notes

The Peanut Butter Cup White Russian is best shaken and served fresh.

You can brew the espresso ahead of time, but it is easiest to melt the peanut butter into it while the coffee is still warm.

If preparing ahead, cool the peanut butter espresso mixture and keep it refrigerated.

Keep the canned White Russian chilled until serving.

Add the chocolate syrup and shake the cocktail shortly before pouring.

Make the marshmallow web at the last minute. Once melted and stretched, marshmallow becomes sticky and can lose its shape as it sits.
