You'll love this peanut butter cup martini

Peanut butter and chocolate are one of those combinations that just work. And when you turn it into a cocktail, it gets even better.

This drink is rich and creamy without being too heavy. It's sweet, but not overly so. And it comes together in about five minutes with just three ingredients.

It's also a great option when you're entertaining. It feels a little fancy, it's easy to batch, and people always ask for the recipe.

Ingredients

Skrewball Peanut Butter Whiskey. The base of this drink. A lot of recipes use chocolate vodka or plain vodka with peanut butter added in, but Skrewball gives you a deep, natural peanut butter flavor without any extra effort. It's sweet on its own, which is exactly what you want in a dessert cocktail.

Chocolate Liqueur. This brings the chocolate side of the equation. I reach for Godiva or Trader Vic's. I prefer non-creamy chocolate liqueurs because they're more versatile. You can always add cream separately, which gives you more control over the final texture.

Irish Cream. This adds a soft, creamy finish. Bailey's is the obvious choice, but any Irish cream works. It ties the peanut butter and chocolate together and gives the cocktail that smooth, dessert-like feel. 

How to make this peanut butter cup martini

1. Add the Skrewball, chocolate liqueur, and Irish cream to a cocktail shaker.
2. Fill with ice and shake well, about 15 to 20 seconds.
3. Strain into a chilled martini glass and enjoy.

That's it. Three ingredients, one shake, done.

Tip: If you don't have a cocktail shaker, a mason jar with a tight-fitting lid works perfectly.

Garnish ideas

A good garnish turns this drink into something you'd order at a bar.

• A Reese's Pieces rim is a favorite. Spread a thin layer of peanut butter around the rim of the glass, then dip it into crushed Reese's Pieces. It looks great and adds a little crunch to every sip.
• A chocolate drizzle is another easy option. Use chocolate syrup and swirl it around the inside of the glass before pouring the cocktail in. You can also drizzle it over the top.
• A mini Reese's cup on the rim is the simplest and most recognizable garnish. It immediately tells people what they're drinking.

Substitutions

If you don't have Irish cream, you can swap it for heavy cream, half-and-half, chocolate milk, or any milk you have on hand. The cocktail will be slightly less rich, but still delicious. Heavy cream gives the closest texture to Bailey's.

If you want a non-creamy version, skip the Irish cream entirely and add a small splash of vanilla extract instead. It won't be as thick, but it still tastes like a peanut butter cup.

FAQs

What alcohol is in a peanut butter cup martini?

A peanut butter cup martini typically contains peanut butter whiskey (like Skrewball), chocolate liqueur, and Irish cream. Some recipes use vodka instead of peanut butter whiskey, but Skrewball gives the drink a more pronounced peanut butter flavor.

What is a good mixer for peanut butter whiskey?

Chocolate liqueur is the best mixer for peanut butter whiskey. It mirrors the chocolate-and-peanut-butter pairing of a Reese's cup. Irish cream, heavy cream, and chocolate milk also work well. For something lighter, try mixing Skrewball with cold brew or cream soda.

Can you make a peanut butter cup martini without Irish cream?

Yes. You can substitute Irish cream with heavy cream, half-and-half, or chocolate milk. Each swap slightly changes the texture, but the drink still tastes great. If you want to skip dairy entirely, oat milk or coconut cream is a good option.

What does Skrewball peanut butter whiskey taste like?

Skrewball tastes like a sweet, smooth peanut butter candy. It's much sweeter than a traditional whiskey and has a distinct peanut butter flavor. It's 35% ABV, so it's lower in alcohol than most spirits but strong enough to be the base of a cocktail.

Can you make this drink ahead of time?

You can pre-mix the ingredients and refrigerate them for a few hours before serving. Shake with ice just before pouring. If you're batching for a crowd, multiply the recipe and keep the mixture chilled until you're ready to shake and serve.
