Kahlua Fudge Ingredients

Ingredients needed to make Kahlua Fudge.

Get ready to make our Kahlua fudge, a straightforward recipe that combines chocolate and coffee liqueur for a rich and satisfying treat. This fudge uses familiar ingredients in a new way to deliver a delicious twist on a classic dessert, perfect for anyone who loves chocolate with a hint of coffee flavor.

Here’s what you’ll need:

3 cups milk chocolate chips
14 ounce can sweetened condensed milk
4 tablespoons unsalted butter, cold and cubed
½ teaspoon instant espresso powder
¼ cup Kahlua rum and coffee liqueur
1 teaspoon vanilla extract

Kahlua Fudge Substitutions and Additions

Milk Chocolate Chips: For a less sweet option, dark chocolate chips semisweet chocolate chips, or white chocolate chips can be used.

Instant Espresso Powder: For a different type of coffee flavor, instant coffee granules can be used in equal amounts. Alternatively, for a non-coffee version, omit this entirely or replace it with cocoa powder to enhance the chocolate flavor.

Vanilla Extract: To experiment with flavors, try using almond extract or hazelnut extract for a nutty undertone, which pairs well with chocolate and coffee.

How To Make Kahlua Fudge

Follow these simple steps to whip up a batch of delicious Kahlua fudge that combines the rich flavors of chocolate and coffee liqueur. This straightforward recipe simplifies the traditional fudge-making process, making it accessible for even beginner cooks.

STEP ONE: Before you begin mixing ingredients, line an eight by eight inch straight-sided metal square baking pan with parchment paper. Make sure the paper is long enough to hang over the sides, which will help in removing the fudge easily after it has set. This preparation prevents sticking and allows for easy cleanup.

STEP TWO: In a large microwave-safe bowl, add three cups of milk chocolate chips, a 14-ounce can of sweetened condensed milk, four tablespoons of cold, cubed unsalted butter, and ½ teaspoon of instant espresso powder.

The chocolate chips, condensed milk, butter, and espresso powder are in a bowl.

Arrange the sweetened condensed milk to cover the chocolate chips as much as possible, but do not stir them yet. Place the cubed butter on top of the other ingredients.

OUR RECIPE DEVELOPER SAYS

Keeping the butter cold and cubed helps it melt more evenly when heated, preventing the mixture from overheating.

STEP THREE: Heat the bowl in the microwave on high for one minute and 30 seconds. After heating, let the ingredients sit in the microwave for about 30 seconds. This allows the chocolate chips to continue softening without direct heat, which helps in achieving a smoother fudge.

STEP FOUR: Remove the bowl from the microwave and add ¼ cup of Kahlua rum and coffee liqueur and one teaspoon of vanilla extract. Whisk everything together until the mixture is fully incorporated and smooth. If the chocolate hasn’t fully melted, microwave the mixture for an additional 20-30 seconds, then stir again.

PRO TIP:

Add the Kahlua and vanilla extract after the initial microwaving to preserve their flavors, which can diminish under too much heat.

STEP FIVE: Pour the fudge mixture into the prepared pan, spreading it into an even layer. Tap the pan gently on the counter to remove any air bubbles and ensure a smooth top.

STEP SIX: Place the pan in the refrigerator and let the fudge set for at least four hours, or overnight, to ensure it hardens properly.

STEP SEVEN: Once set, use the overhanging parchment paper to lift the fudge out of the pan. Transfer it to a cutting board and cut the fudge into 64 one-inch pieces.

Troubleshooting This Kahlua Fudge Recipe

The fudge is too soft or hasn’t set properly.
Make sure to chill the fudge for at least four hours or preferably overnight to give it enough time to set completely.

The chocolate burns or seizes in the microwave.
Heat the chocolate mixture in short bursts in the microwave, stirring between each burst to prevent overheating, which can cause the chocolate to seize.

The fudge mixture is lumpy after mixing.
Ensure that the chocolate chips are completely covered by the sweetened condensed milk before microwaving, and whisk vigorously after heating to break down any lumps.

The fudge has a grainy texture.
To avoid a grainy texture, make sure to cut the butter into small cubes to help it melt evenly and avoid overheating the chocolate.

The flavors of Kahlua and espresso are too subtle.
Add the Kahlua and espresso after the initial microwaving to preserve their aromatic flavors, which can diminish if added too early or exposed to too much heat.

How To Serve Kahlua Fudge

Kahlua fudge is versatile and works wonderfully at a variety of gatherings, from casual to formal. Here are a few ideal occasions to serve it, along with drink and dessert pairing ideas that highlight the fudge’s coffee-chocolate richness:

Casual Family Gatherings: For a relaxed family evening, serve Kahlua liqueur fudge with a scoop of vanilla ice cream on top of the fudge. Pair it with an iced caramel latte to enhance the fudge’s coffee undertones in a refreshing way.
Holiday Celebrations: Add Kahlua fudge to the holiday dessert table alongside a caramel apple dump cake, which brings cozy fall flavors of apple and caramel, perfect for Thanksgiving or Christmas. Pair it with your favorite cocktail, like a warm drunken Rudolph Fireball hot chocolate (a spiced, adult-friendly drink) that complements the fudge’s richness.
Elegant Dinner Parties: For formal dinners, serve Kahlua fudge with chocolate mint cheesecake as a sophisticated duo. Pair this with a party punch for a light, citrusy contrast to the richer flavors of the fudge and cheesecake, creating a balanced end to a delicious meal
Cold Drink: An iced mocha can be a fitting beverage choice, providing a chilled, coffee-infused counterpart to the treats

How To Store Kahlua Fudge

To keep your Kahlua fudge fresh and delicious, here are some simple storage options and tips to make it ahead for any occasion.

MAKE AHEAD: Kahlua fudge can be prepared in advance, making it a convenient option for gatherings or gifts. After the fudge is fully set in the refrigerator, you can keep it in an airtight container for easy storage. This way, it’s ready to slice and serve whenever you need it.

IN THE FRIDGE: Store Kahlua fudge in an airtight container in the refrigerator to keep it fresh. It will last up to two weeks, and the chilled storage helps maintain its smooth texture and flavor.

IN THE FREEZER: To freeze, wrap the fudge tightly in plastic wrap and then place it in a freezer-safe Ziplock bag or container. Stored this way, the fudge will last up to three months. When you’re ready to enjoy it, let it thaw in the refrigerator overnight.

REHEATING: If you prefer your fudge slightly softened, you can microwave individual squares for just a few seconds. Start with 5-10 seconds, as microwaving for too long can cause the fudge to melt.

Ingredients

3 cups milk chocolate chips
14 ounces sweetened condensed milk
4 tablespoons unsalted butter, cold and cubed
½ teaspoon instant espresso powder
¼ cup Kahlua rum and coffee liqueur
1 teaspoon vanilla extract

Instructions

Line an 8×8 straight sided metal baking pan with parchment paper. Be sure to have a long enough piece to allow enough of the parchment paper to hang over the sides. This will make lifting the Kahlua fudge out of the pan easier after refrigeration for slicing into individual portions.
In a large microwave safe bowl add the milk chocolate chips, sweetened condensed milk, unsalted butter and instant espresso powder. Be sure to cover as much of the milk chocolate chips as possible with the sweetened condensed milk but do not stir at this point. The butter cubes should be on the top of the other ingredients.
Microwave on high for 1 minute 30 seconds. Allow the ingredients to sit for 30 seconds in the bowl, to allow the chips to continue to soften, before adding the Kahlua and vanilla extract. Whisk until all the ingredients are fully incorporated and the fudge is smooth. You may need to heat the mixture for an additional 20-30 seconds if needed to get a smooth Kahlua fudge mixture.
Pour the Kahlua fudge into the prepared metal baking pan and spread it into an even layer. Tap the pan on the counter a couple times to force any air bubbles that may be in the fudge to the surface.
Place the Kahlua fudge into the refrigerator to set for a minimum of 4 hours or up to overnight.
Once the fudge has set, and hardened, gently lift the overhanging parchment paper and lift the fudge from the pan. Place the fudge onto a cutting board and slice it into 64 1×1 inch pieces. Plate and serve.

Notes

Be sure to label this fudge as “adults only” as the alcohol from the Kahlua liqueur does not cook off at all when made.
Be sure that you are using instant espresso powder and not just ground espresso beans to add to the recipe. The amount does not give an overwhelming coffee flavor, it just enhances the flavor of the chocolate and Kahlua in the fudge. You can adjust the amount to use a little more, or less, according to your preferences or you can choose to omit it if desired.
Be sure to use a good quality brand of milk chocolate chips (Ghirardelli brand was used for this recipe) as they will melt and taste much better than some of the generic or store brands will.
A 1000 watt microwave was used for melting the chocolate chips for this recipe. You may have to adjust the amount of time, and strength, for your fudge according to the microwave you use.
If you do not have a microwave, you can heat the same ingredients in a double boiler over medium heat until the chips start to melt. Be very careful not to get any moisture from the double boiler into the bowl or it can cause the chocolate chips to seize up when stirring. If this happens, you will need to start over with a new batch of ingredients.
You can not substitute evaporated milk for the sweetened condensed milk in this recipe. They are typically sold in the same sections in the grocery store baking aisle but they are not interchangeable.
You can stir in ½ cup chopped walnuts to the warm fudge mixture before pouring it into the prepared 8×8 pan. You can also sprinkle some extra chopped nuts to the top of the fudge, as a garnish, before refrigerating the Kahlua fudge to set.
You can cut this fudge into larger pieces if desired. I find that if I cut rows of 5×5 it will yield 25 pieces, or 6×6 it will yield 36 pieces of Kahlua fudge from this size pan.
