Ingredients

See? I wasn't joking when I said two ingredients are all you need to make this peanut butter cocktail. Now let's chat about our star ingredient, which is essential to this recipe.

Skrewball peanut butter whiskey: Made with real peanuts, Skrewball peanut butter whiskey features honey, vanilla and praline notes, and it tastes just like its name suggests. With its viscous mouthfeel, this liquor is thicker than a traditional whiskey. In fact, it's more like sipping on a liqueur or port wine.

Think you don't like whiskey? I still recommend trying it, particularly if you have a sweet tooth.

While we all have different tastes, the added sweetness makes it a great entry-level whiskey. Peanut butter takes center stage while the whiskey flavor is less prominent. Plus, it goes down incredibly smoothly with minimal heat.

Step-by-Step Instructions

Step 1: Grab a rocks glass and pour in that delicious peanut butter liquor (photo 1).

Recipe FAQs

Are there other brands of peanut butter whiskey?

Skrewball is not the only brand of peanut butter whiskey, but it is the first of its kind, best known in the market and widely regarded as the top distiller in many reviews and accolades. Some other brands include Ole Smoky and Sqrrl. While you're more than welcome to try other brands, this recipe was specifically developed using Skrewball. Needless to say, I'm a fan.

Is peanut butter whiskey actually whiskey?

This liquor falls into the flavored whiskey category. A traditional whiskey is defined as an 80-proof distilled liquor from malted grains that spends at least some time in an oak barrel. This peanut butter whiskey is 75 proof, so it's classified as a flavored whiskey. Whether you call it a flavored whiskey or just whiskey, it's a delight either way.

Is there peanut butter in peanut butter whiskey?

This whiskey is made from a corn and barley base with added real peanuts and pure sugar cane. When they all come together, the result tastes like a boozy liquid peanut butter. Delicious! Pour me another, please.

Expert Tips

While you can certainly use standard ice cubes, I prefer to make an old fashioned with one large ice cube. This type of ice cube melts more slowly to ensure your drink doesn't get too watered down.
That said, if the peanut butter whiskey is too sweet for your taste, you can add a bar spoon of water to the mixture. I love it as is, but we all have different palates.
Feel free to experiment with the bitters. To keep it simple, I used angostura bitters, but there are so many bitter flavors that would be wonderful. Think orange, chocolate or ginger!
To make the orange peel garnish, cut off the bottom of the orange to give it stability. Then, use a paring knife to cut the orange about 2 inches wide and all the way down the length of the fruit. Try to make the cut shallow enough that it's pith rather than fruit on the other side of the peel, but a little bit of fruit isn't a deal breaker.

Perfect Pairing
