It's time to indulge in your campfire dreams and there's no need for a fire or to even be outside. This boozy s'mores milkshake recipe can be enjoyed anywhere and is filled with all the delicious flavors found in those gooey s'mores. It's simply served in a glass and is definitely for adults only.

The recipe brings together everything there is to love about s'mores. To begin, you'll choose your favorite marshmallow vodka and chocolate liqueur. The Drambuie adds a honey flavor that imitates graham crackers, and RumChata puts the "milk" in the milkshake. Add a little ice cream, blend it up, then dress it with toasted marshmallows, chocolate, and graham crackers.

This is a very fun frozen cocktail that you can play with to your heart's content. It also deserves to be shared, so invite a few friends over and get roasting and blending.


  • 1 1/2 ounces marshmallow vodka
  • 1 ounce chocolate liqueur
  • 1 ounce Drambuie
  • 1/2 ounce RumChata
  • 2 scoops vanilla ice cream (more to thicken the shake as desired)
  • Garnish: chocolate syrup
  • Garnish: crushed graham crackers (for rim)
  • Garnish: toasted marshmallow
  • Garnish: chocolate shavings

Steps to Make It

  1. Gather the ingredients.

  2. Rim a tall glass with graham crackers if you like and drizzle chocolate syrup inside the glass. Place it in the freezer.

  3. In a blender, combine the liquors and ice cream and blend until smooth. To create a thicker shake, add more ice cream. If it's too thick, add more RumChata.

  4. Pour the blended shake into the prepared frozen glass.

  5. Garnish with a toasted marshmallow and chocolate shavings.

  6. Serve and enjoy!

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat resistant, tempered glass products can, and do, break occasionally.


  • This recipe can easily be divided into two shorter glasses and it looks great in a cocktail glass. Splitting it also gives you the opportunity to make any personal adjustments to the recipe in a second round.
  • When it comes to the chocolate liqueur, you have quite a few options. Crème de cacao is a good choice and either the white or dark versions may already be in your bar. If you want to get decadent, pour a creamy chocolate liqueur such as Godiva.
  • To crush graham crackers, chop them in a blender or food processor. You can also place them into a plastic zipper bag and smash them into fine pieces using a cocktail muddler or any blunt object you have in the kitchen. The smaller the bits, the better for rimming the glass
  • To rim the glass, dip the rim into a shallow dish of either chocolate syrup or RumChata to wet the rim. Then, dip the rim into a small plate filled with crushed crackers until you get a nice, even coating. Shake off any loose crackers.

Recipe Variations

  • If you'd like to skip the task of rimming, sprinkle crushed graham crackers over the drink after adding the marshmallow. You can also add shaved chocolate, mini chocolate chips, or a drizzle of chocolate syrup to the top instead of (or along with) the syrup in the glass.
  • Marshmallow vodka is the obvious choice for any s'mores cocktail and this is the perfect excuse to pick up a bottle. If you prefer, try vanilla or whipped cream vodka instead.
  • Rather than Drambuie, pour Bärenjäger instead. You can also simply use 1 tablespoon of honey.
  • While vanilla ice cream is recommended, there's no reason you can't switch it up. Options include splitting it with chocolate ice cream, using a fun flavor like rocky road, or even switching to chocolate chip ice cream.

The Toasted Marshmallows

You don't need a campfire to roast marshmallows and there are a few ways to make them right there in your kitchen. Be careful not to start a kitchen fire, of course. 

  • If you have a culinary torch, you can toast them with that.

  • Use the burner on a gas stove by skewering the marshmallows and holding them a few inches from the flame.

  • Turn on the broiler of your oven, place the marshmallows on a pan 2 to 3 inches from the flame. Watch carefully as it should take just a minute or two to get the perfect char.

  • Of course, if you have a fire or the grill going, nothing beats a roasted marshmallow over either of those.

How Strong Is a Boozy S'mores Milkshake?

With four liquors and only ice cream to knock it down, this is one of the strongest blended cocktails you can mix up. It's not bad, though. The milkshake's alcohol content is about 15 percent ABV (30 proof), making it slightly stronger than a glass of wine.
