To make a chocolate martini, shake 1½ oz vodka, 1 oz Irish cream liqueur, 1 oz crème de cacao and 1 tablespoon of homemade cocoa syrup with ice for 15 seconds, then strain it into a chilled glass rimmed with cocoa and sugar. The cocoa syrup (unsweetened cocoa powder, sugar and hot water) gives a deeper chocolate taste than bottled syrup. It makes 1 cocktail.
Most chocolate martinis lean on store-bought chocolate syrup, which tastes more of sugar than of chocolate. Two spoonfuls of unsweetened cacao powder fix that: one goes into a quick syrup that dissolves cleanly in a cold drink, the other into a dark, bittersweet rim. Below you will find the classic version, three holiday variations, an alcohol-free chocolate “mocktini,” and fixes for a gritty or too-sweet glass.
What is in a chocolate martini?
A chocolate martini is a creamy dessert cocktail, not a true martini: there is no gin or vermouth, just the glass and the shaking method. The usual base is vodka plus one or two chocolate or cream liqueurs. Crème de cacao brings a light cocoa-vanilla sweetness, Irish cream brings body and a milky color, and a chocolate rim or garnish makes it look like dessert.
Our version adds a little cocoa syrup made from unsweetened cocoa powder. Because the cocoa is bloomed in hot water first, it blends smoothly into the cold drink and adds real chocolate depth without extra liqueur.
What do you need for a chocolate martini?
Makes: 1 cocktail (plus syrup for about 3 more) · Prep: 10 minutes · Total: 10 minutes, plus chilling the glass
Cocoa syrup
- 2 tablespoons (10 g) unsweetened cocoa or cacao powder
- 2 tablespoons (25 g) granulated sugar
- 3 tablespoons (45 ml) hot water
- Pinch of fine salt
Cocoa-sugar rim
- 1 teaspoon unsweetened cocoa or cacao powder
- 1 tablespoon granulated or superfine sugar
Cocktail
- 1½ oz (45 ml) vodka
- 1 oz (30 ml) Irish cream liqueur
- 1 oz (30 ml) crème de cacao (dark or white) or chocolate liqueur
- 1 tablespoon (15 ml) cocoa syrup
- ½ oz (15 ml) half-and-half (optional, for a creamier drink)
- Ice
- Dark chocolate shavings, to garnish (optional)
How do you make a chocolate martini?
- Chill the glass. Put a martini or coupe glass in the freezer for 10 minutes, or fill it with ice water while you make the syrup.
- Make the cocoa syrup. In a small cup, stir the cocoa, sugar and salt, then pour in the hot water and stir until smooth and glossy, about 30 seconds. Let it cool for a few minutes.
- Rim the glass. Mix the rim cocoa and sugar on a small plate. Empty and dry the glass, dip the rim about ¼ inch into a saucer of cocoa syrup, then press it into the cocoa sugar and turn gently.
- Shake. Fill a cocktail shaker two-thirds with ice. Add the vodka, Irish cream, crème de cacao, 1 tablespoon of cocoa syrup and the half-and-half, if using. Seal and shake hard for 15 seconds, until the shaker feels frosty.
- Strain and serve. Strain into the rimmed glass without touching the rim, top with a few chocolate shavings and serve right away.
Please enjoy responsibly and only if you are of legal drinking age (21+ in the US). The 1½ oz of vodka alone is one US standard drink, so this cocktail adds up to more than one.
Why make the syrup with cocoa powder?
Dry cocoa does not dissolve in a cold, alcoholic drink; it clumps and settles as grit at the bottom of the glass. Stirring it into hot water first wets every particle and releases more chocolate flavor, the same “blooming” step we use for hot chocolate with cocoa powder. The result is a smooth syrup you control: less sugar than most bottled chocolate syrups and a clearer cocoa taste.
The recipe makes about ¼ cup, enough for 4 drinks. Covered in the fridge it keeps about a week; stir it before using, since it thickens as it chills. It is also good in iced coffee, so try it in a homemade mocha.
What are the best chocolate martini variations?
| Variation | Change to the classic | Garnish |
|---|---|---|
| Dark chocolate martini | Skip the Irish cream; use 2 oz vodka, 1 oz dark crème de cacao and 2 tbsp cocoa syrup | Cocoa-sugar rim, dark chocolate curl |
| Peppermint chocolate martini | Add ½ oz peppermint schnapps; reduce vodka to 1 oz | Crushed candy cane mixed into the rim sugar |
| Espresso chocolate martini | Add 1 oz cooled espresso; reduce vodka to 1 oz | Three coffee beans, cocoa dusting |
| White chocolate martini | Use white crème de cacao and skip the cocoa syrup | Cocoa dusted over half the rim for contrast |
For a holiday party, mix the syrup and rim sugar in the morning and rim the glasses an hour ahead; they keep their rims in the fridge. Shake each drink to order so it stays cold and frothy. For more peppermint ideas, see our peppermint hot chocolate.
How do you make a chocolate martini without alcohol?
Shake 3 oz (90 ml) cold whole milk, 2 tablespoons cocoa syrup, 1 oz (30 ml) heavy cream and ¼ teaspoon vanilla extract with ice for 15 seconds, then strain into the cocoa-rimmed glass. Add 1 oz of cooled espresso for a grown-up, coffee-shop flavor. It looks just like the cocktail, so everyone at the table gets the same dessert drink. For a warm version on a cold night, our Christmas hot chocolate uses the same cocoa base.
Why is my chocolate martini gritty or too sweet?
| Problem | Cause | Fix |
|---|---|---|
| Gritty bits at the bottom | Dry cocoa added straight to the shaker | Always use the cocoa syrup, made with hot water |
| Too sweet | Sweet liqueurs plus extra syrup | Use dark crème de cacao and cut the syrup to 1 tsp |
| Thin and watery | Shaken too long or with too little ice | Fill the shaker two-thirds with ice; shake 15 seconds |
| Rim falls into the drink | Rim dipped too deep or wet glass | Dry the glass; dip only the outer ¼ inch |
| Not chocolatey enough | White crème de cacao, no syrup | Add 1 more tbsp cocoa syrup or use dark crème de cacao |
Which cocoa powder is best for a chocolate martini?
Any unsweetened cocoa works because nothing needs to rise. Dutch-process cocoa makes a darker rim and a mellow, classic chocolate flavor. Natural cocoa gives a reddish-brown rim and a brighter, fruitier syrup that stands up well to the creamy liqueurs.
Grevista distributes a natural, non-alkalized cocoa (what many shoppers call cacao powder) made from single-origin Vietnamese Trinitario cacao grown in Đắk Lắk; its fruity notes show clearly in the syrup and on the rim. See sizes on the Grevista cocoa powder page. If you are planning a dessert table around the drinks, our chocolate truffles with cocoa powder and a hot cocoa bar pair well with a tray of chocolate martinis.
Frequently asked questions
Can I use cacao powder in a chocolate martini?
Yes, use it 1:1 in the syrup and the rim. Most products sold as cacao powder are natural, non-alkalized cocoa, so the syrup tastes a little fruitier and the rim looks reddish-brown.
What can I use instead of crème de cacao?
Use 1 oz of any chocolate liqueur, or replace it with 1 more tablespoon of cocoa syrup and ½ oz more vodka. The drink will be less sweet and more cocoa-forward.
Can I make chocolate martinis ahead for a party?
Mix the vodka, liqueurs and syrup in a bottle up to a day ahead and chill it. Shake each serving with ice just before pouring, since the shaking chills and slightly dilutes the drink.
How do I keep the cocoa rim from sticking unevenly?
Use cocoa syrup instead of water to wet the rim, and press the glass straight down into the cocoa sugar before turning it. Sifted cocoa and superfine sugar give the neatest edge.
