Homemade Kahlua Coffee Liqueur Recipe
The Kahlua coffee liqueur is a main part of loads of cocktails. The company has a huge following, and all bars have it on stock.
The drink is so popular, the company that makes it even has Salma Hayek in their adverts!
But what if you don’t have any Kahlua at home?
Fear not, I will show you how to make it right now.
What is a Kahlua Coffee Liqueur?
Hailing from Mexico, Kahlua gained worldwide fame with its rich blend of rum and coffee. You can enjoy it on its own, mix it into a cocktail, and use it as an ingredient for desserts.
Loads of cocktails use it, including:
- Espresso Martini (check out my recipe)
- B52s
- White Russian
- etc.
As you know, I love coffee in all shapes and forms, so it won’t surprise you that I have a coffee based cocktail every now and then. And while I could just buy Kahlua, it is much more fun making it at home. I also gift it during the Holidays (instead of egg nog).
Anyhow, here is the recipe that has worked well for me, it is pretty much like the real thing.
Equipment and Ingredients for our Copycat Kahlua Coffee Liqueur
Here are the things you need for your Kahlua coffee:
- 4 cups water – Provides liquid for dissolving sugar and instant coffee.
- 2 cups sugar – Adds sweetness to the Kahlua.
- 3 tbsp instant coffee – Adds a strong coffee flavor to mimic the taste of real Kahlua.
- 1/2 cup light corn syrup – Gives a slight syrupy texture similar to authentic Kahlua. I know many people don’t like to use corn syrup, but it gives a viscosity that is hard to emulate otherwise. If you leave it out, you will need even more sugar, perhaps even caramelized.
- 2 and 1/4 cups of rum (white or dark) – Serves as an alcohol base for the homemade Kahlua, achieving a 20% alcohol content like real Kahlua.
- 1 tbsp vanilla extract – Enhances the overall flavor profile of the homemade Kahlua.
Now that you’ve got what you need, it’s time to make your DIY Kahlua.
Step-by-Step Guide to Making a Kahlua Coffee Liqueur
Making a Kahlua coffee liqueur is not that complicated. Just follow these steps:
1. Combine the water, sugar, and coffee and heat to a boil.
- In a pot, combine water, sugar, and instant coffee. Granulated sugar is what I find to be the best choice to pull off a smooth caramelization.
- Place on medium to medium-high heat until the mixture comes to a boil.
2. Let simmer and stir occasionally for an hour.
- After the mixture boils, reduce it to a simmer.
- Stir it occasionally for exactly an hour.
3. Remove from heat and add the light corn syrup.
- Remove the pot from the stove.
- While hot, add the light corn syrup and stir gently.
4. Cool down until room temperature and add the vanilla extract.
- Let the mixture cool down completely for about 15-20 minutes until room temperature.
- Add the vanilla extract and give it another stir.
5. Add the rum and mix.
- Now it’s time to add the rum and mix to complete your Kahlua.
- Remember never to add the rum while the mixture is hot so the alcohol will not cook out.
6. Transfer into bottles and serve.
- Transfer it to your bottles. I recommend using a funnel to make this step easier.
- Pour yourself a glass, and enjoy.
How to serve a Kahlua coffee liqueur?
The Kahlua liqueur is best when used as part of a cocktail, so you’ll want to store it in a bottle you can seal tightly. Just like the real stuff, only home made 😉
Tips to Making a Kahlua Coffee Liqueur
Here are some extra tips you can try to enjoy more of your Kahlua:
- Brewed coffee also works: While instant coffee works great and is convenient for this recipe, you can also use brewed coffee if you want to choose your own coffee beans. I don’t have any recommendations on this though, I’ve only used the instant coffee version.
- Add vodka to make a White Russian: With a Kahlua, you can then make the popular cocktail White Russian. Combine equal parts of Kahlua, vodka, and heavy cream then add ice and enjoy. You can also use this for my Espresso Martini recipe.
- Turn it into desserts: You can also infuse this alcoholic coffee drink into desserts. You can combine strong coffee and Kahlua into a boxed cake mix to make Kahlua Fudge. Another must-try treat is a White Russian mixed with ice and Bailey’s Irish cream thrown into the blender and drizzled with chocolate syrup for a mudslide.

Kahlua is a delectable drink with its smooth texture and a combo of coffee, vanilla, and caramel flavors fused into one booze. Try out this recipe and enjoy both the caffeine and alcohol combined.
Just a newbie question here, but can we use any type of rum for this recipe? Would spiced rum add too much to the flavor profile, or should I stick with white rum as suggested?
That will create a different flavor, but it’s always good to experiment 🙂
I’m curious, Tom, can you use brewed espresso instead of instant coffee if you’re looking for a stronger coffee profile? Also, would adjusting the sugar for taste imbalance the liqueur?
Instant coffee is pretty strong, I don’t really see any benefit of using espresso here. But of course, you can use it. 16g of instant coffee is enough for 2-3 espressos.
Tom, your step-by-step guide is golden – thank you. One tiny insight from my experience: try using a dark roasted coffee. It really mimics the depth of flavor you find in commercial Kahlua.
I just followed your recipe, and the result is divine. Last time I bought Kahlua, I remember thinking it couldn’t be too hard to replicate, and your recipe proved me right. Sharing homemade liqueurs for the holidays is now my new tradition 😉
