How to Make a Classic Kahlúa Coffee Drink

Want to make a Kahlúa coffee just like they do in Mexico or the U.S., but unsure whether to use hot or cold coffee—or how much liqueur and sugar to add? This guide lays out the classic formula used in both regions with exact measurements, so you can recreate the drink the authentic way.

To make a traditional Kahlúa coffee, combine 10g white sugar, 20cc coffee liqueur (like Kahlúa), 150cc brewed coffee (hot in the West, cold in Mexico), and top with 20cc lightly whipped cream—do not stir the cream into the drink.

What Is a Kahlúa Coffee?

Kahlúa coffee is a sweet, spirited coffee cocktail combining brewed coffee, coffee liqueur (typically Kahlúa), sugar, and a float of whipped cream. It’s especially popular in Mexico and the United States, where it’s served either hot or cold depending on local custom. The drink balances bitter coffee, sweet cream, and smooth coffee liqueur for a dessert-like caffeine hit.

What Ingredients Are Needed?

The classic recipe uses the following measured components:

• 150cc of dark roasted coffee (150 milliliters)
• 20cc of coffee liqueur (specifically Kahlúa or similar Mexican coffee liqueur)
• 10g of white granulated sugar
• 20cc of lightly whipped cream (for topping)

In some versions, the coffee is served hot (common in Europe and the U.S.), while in Mexico it’s typically served cold.

How Do You Make It Step by Step?

Here’s the straightforward, repeatable method:

1. Place 10g of white sugar at the bottom of your serving glass.
2. Pour 20cc of coffee liqueur (e.g., Kahlúa) over the sugar.
3. Add 150cc of brewed coffee. Use hot coffee if you're in the U.S. or Europe, or cold coffee if following the Mexican style.
4. Gently float 20cc of lightly whipped cream on top of the drink. Do not stir the cream into the coffee—it’s meant to sit as a rich, separate layer.

Hot vs. Cold Coffee: What’s the Difference?

The coffee base can be either hot or cold:

• In Mexico, it’s standard to use cold coffee, making the drink more of a chilled dessert cocktail.
• In the U.S. and much of Europe, hot coffee is preferred, turning it into a warming after-dinner drink similar to an Irish coffee without the whiskey.

The rest of the ingredients—sugar, liqueur, and cream—remain the same regardless of temperature.

Why Use These Ratios?

The specified amounts are traditional and balanced:

• 10g sugar sweetens the liqueur and coffee without overpowering the bitterness.
• 20cc of coffee liqueur provides a strong coffee-alcohol flavor without making the drink too boozy.
• 150cc coffee ensures a robust base, whether hot or cold.
• 20cc of cream tops the drink for contrast and texture.

These proportions let each element—coffee, alcohol, sweetness, and cream—shine without clashing.

Frequently Asked Questions

Can I use any coffee liqueur, or does it have to be Kahlúa?

The recipe traditionally calls for Kahlúa, a Mexican coffee liqueur. While you can try other coffee liqueurs, Kahlúa is specifically balanced for this drink with its distinct coffee and vanilla notes. Substituting with another brand may alter the expected flavor profile.

Should the coffee be espresso or regular drip coffee?

The original recipe simply specifies “deep-roasted coffee” (150cc). It doesn’t require espresso. Use a strong, dark roasted brew—either filter or espresso-style—as long as the volume is around 150cc. The coffee’s role is to balance the liqueur, not to dominate as a shot.

Is it better to use hot or cold coffee?

It depends on regional tradition and personal taste. In the U.S. and Europe, hot coffee is typical, creating a cozy, dessert-like drink. In Mexico, cold coffee is standard, resulting in a refreshing, chilled cocktail version. Both are equally authentic.

Can I make this drink without alcohol?

You can omit the coffee liqueur, but it will no longer be a true Kahlúa coffee. The liqueur is central to the flavor. For a non-alcoholic version, you might substitute a strong coffee syrup, though the taste and experience will differ significantly.

Do I mix the whipped cream into the drink?

No. The 20cc of whipped cream is meant to float on top. It’s not stirred in. This creates a contrast between the creamy top and the sweet, boozy coffee beneath—part of the drink’s classic presentation.
