Brownies with Kahlúa

If you’re looking for a simple, flavorful twist on traditional brownies, you’ve found it. This classic from-scratch brownie recipe integrates the Mexican coffee liqueur Kahlúa, a classic cocktail addition or after-dinner drink that’s 20% ABV.

However, those concerned about too much booziness can rest assured that most of the alcohol cooks off during the quick, half-hour baking process.

What makes Kahlúa brownies so good? 

Bakers have been integrating coffee into chocolate baked goods for decades, as the two flavors pair beautifully, creating a rich, robust taste that can’t be matched with just chocolate alone. Kahlúa provides the benefit of some of the most concentrated, intense coffee flavoring possible.

In addition, the simple enhancement of chopped walnuts adds a perfect texture contrast and nuttiness. 

Why you’ll love this Kahlúa brownies recipe 

For one, this is an ideal recipe for weeknight baking or a late-night snack. The complex, unique flavors come together in just 40 minutes total, 30 of which are hands-off time in the oven.

Meanwhile, other than the addition of the distinctive coffee liqueur, the list of ingredients should look familiar to those who’ve made brownies from scratch in the past. This means a shorter shopping list since most are already in your fridge or pantry.

Recipe variations

It’s relatively easy to modify this recipe for different dietary needs or preferences.

Those with nut allergies can simply omit the chopped walnuts.

Bakers avoiding gluten can swap out the all-purpose flour for many cup-for-cup gluten-free flour blends.

What to serve with Kahlúa brownies 

Kahlúa brownies are a wonderfully versatile snack that can fit nearly any type of situation or craving. For a decadent dessert, combine a warm Kahlúa brownie with a scoop of ice cream.

Or, contrast the richness of the brownie with fresh fruit, particularly choices like strawberries that pair well with chocolate.

Wash it down with the beverage of your choice, whether it’s a cold glass of milk, a hot cup of coffee to double down on the java flavor, or even a shot of Kahlúa itself (for those over 21) to sip as you enjoy the delicious baked good.

How to store

Kahlúa brownies are easy to store in several ways. In all cases, let them cool to room temperature before packing them up.

The most straightforward method involves keeping your brownies in an airtight container out of direct sunlight, where they’ll stay fresh for three to four days. You can extend this up to about a week by refrigerating them, though this can lead to a denser, fudgier texture. 

Kahlúa brownies from scratch can even be frozen for longer-term storage. Wrap them tightly in plastic wrap and foil, or store them in plastic freezer bags. Freezing them individually sliced and wrapped can make it easy to defrost the amount you need, though more care needs to be taken to avoid freezer burn compared to freezing an entire tray’s worth. They’ll last up to three months.  

How to reheat

If you’ve frozen your brownies, allow them to thaw gently in the fridge overnight before reheating. In most cases, just a few seconds in the microwave will typically be enough to warm the Kahlúa brownies, while a few minutes in a toaster oven or regular oven on low heat will also work.

Of course, many find these brownies just as enjoyable at room temperature or even slightly chilled!
