  • 4 large egg yolks
  • ¼ cup granulated sugar
  • 1 tbsp instant espresso powder
  • 2 tbsp cocoa powder
  • ¼ cup Irish whiskey
  • 1 cup irish cream liqueur (such as Baileys)

Coffee Crusted Mousse Ingredients:

All of the ingredients required for these recipes are readily available in supermarkets. The bolded ingredients are primary ingredients that give the mousse its flavor and texture. Heavy cream gives a rich and creamy consistency, while egg yolks and granulated sugar give a yellowish tinge to the mixture. Instant espresso powder adds a rich coffee flavor, while cocoa powder lends a slight bittersweet taste. Meanwhile, Irish whiskey adds a distinctive kick to the mousse which elevates its taste to a new level. Lastly, Baileys or any brand of Irish cream liqueur is added to give it a complete Irish coffee profile.

The coffee-crusted mousse also follows suit with similar primary ingredients such as chocolate instant pudding, whole milk, cold brewed coffee plus whiskey or Irish whiskey. Semisweet chocolate shavings add an extra wow-factor with their sweet and bitter combination providing a smooth and velvety finish to this iconic dessert recipe.

The Recipe How-To

“Indulge in a masterpiece of Irish coffee and mousse.”

Step 1: Make the Irish coffee mousse base.

In a small saucepan, whisk together 4 large egg yolks, 1/4 cup granulated sugar, and 1 cup whole milk. Cook over medium heat for 5 to 7 minutes, stirring constantly until the mixture thickens enough to coat the back of a spoon.

Remove from heat and whisk in 1 packet of gelatin that has been dissolved in 1/4 cup cold water. Set aside.

Step 2: Prepare the coffee crusted layer.

In a bowl, mix 3 tbsp instant espresso with 1/4 cup granulated sugar and 1/4 cup cocoa powder until combined.

In a separate bowl, whip 2 cups heavy cream until soft peaks form. Gently fold the cocoa-espresso mixture into the whipped cream.

Step 3: Add Irish cream liqueur and whiskey to create the Irish coffee flavor.

Add 3/4 cup Irish whiskey, 1/4 cup Baileys, or other Irish cream liqueur to the prepared Irish coffee mousse base.

Then, gently fold in half of the whipped cream mixture.

Step 4: Add chocolate instant pudding mix and semisweet chocolate to create the chocolate layer.

To the remaining half of whipped cream mixture, add one package of chocolate instant pudding mix and gently fold in.

Melt 8 oz of semisweet chocolate over low heat, stirring until smooth. Remove from heat and allow it to cool slightly before folding it into the chocolate-whipped cream mixture.

Step 5: Assemble the layers and chill for several hours before serving.

In a 9-inch springform pan or individual ramekins, add a layer of coffee mixture followed by a layer of chocolate mixture alternately.

Cover tightly with plastic wrap and chill in the refrigerator for at least 4 hours, but ideally overnight.

To serve, remove from the refrigerator and let it sit at room temperature for 10-15 minutes. Cut into slices or spoon into dessert cups and garnish with whipped cream and chocolate shavings.

Substitutions and Variations

“Get ready to have your taste buds sing!”

Irish Coffee Mousse is already a delicious dessert on its own, but you can also make it even more interesting by trying out different substitutions and variations. Here are some ideas to mix things up and suit the preferences of coffee and chocolate lovers alike:

1. Coffee Flavors: Instead of using instant espresso, add a shot of freshly made strong coffee to the mousse mixture. You can also use flavored coffee or syrups to infuse different flavors into your mousse.

2. Whiskey Variations: If you’re not a fan of Irish whiskey, you can still enjoy this dessert with other types of whiskey or bourbon. You can also substitute it with rum or brandy for a unique twist.

3. Liqueur Options: Instead of Bailey’s, try using other cream liqueurs such as Kahlua or Amarula for a different flavor profile. You can also experiment with non-cream liqueurs like amaretto, Frangelico or Grand Marnier.

4. Chocolate Additions: Create a chocolate layer on top by spreading melted chocolate over the mousse and chill until set. Garnish your Irish Coffee Mousse with chopped chocolate pieces, cocoa nibs, or grated chocolate for extra texture and depth.

5. Decoration Options: Top off your mousse with whipped cream or a sprinkle of cocoa powder. You can also get creative with garnishes such as coffee beans, mint leaves or chocolate shavings.

Remember that these substitution ideas are just suggestions – feel free to mix and match ingredients to create your perfect Irish Coffee Mousse recipe!

Serving and Pairing

“A perfect pick-me-up for any time of the day.”

If you’re serving Irish Coffee Mousse for dessert, consider pairing it with some complementary flavors to enhance the experience. I recommend serving it alongside a hot cup of coffee or espresso, as well as some chocolate shavings or cocoa powder sprinkled on top.

If you want to take it to the next level, you could even try pairing it with a small glass of Irish whiskey or Irish cream liqueur. This will add an adult twist to the dessert and complement the flavors of the mousse.

Another idea is to pair it with a simple sugar cookie or shortbread biscuit. The mild sweetness of these cookies will not overpower the mousse, but they will create a nice contrast in texture.

Overall, Irish Coffee Mousse is a versatile dessert that can be served in many different ways and paired with various flavors. Experiment until you find your perfect pairings!

Make-Ahead, Storing and Reheating

“Satisfy your sweet tooth with a touch of caffeine.”

One of the best things about this irish coffee mousse recipe is that it can be made ahead of time, stored in the fridge and reheated, and it will still taste just as delicious as when it was first made.

If you plan on making it ahead of time, I recommend refrigerating it for at least 2 hours before serving. The longer you leave it, the more set it will become, which will give it a denser texture. If you prefer a lighter texture, serve it sooner.

If you have any leftovers, store them in an airtight container in the refrigerator. This will keep your mousse fresh for up to 3 days. Make sure to take the mousse out of the refrigerator about an hour before serving to reach room temperature.

Reheating your irish coffee mousse is easy. Just put your portion on a microwave-safe plate and heat for 10-15 seconds. Alternatively, you can reheat it in a saucepan over low heat until warm.

One thing to keep in mind when reheating is that the whipped cream might slightly deflate with reheating. To prevent this from happening too much, avoid overheating the mousse and only heat it in short increments.

Whether you’re making this irish coffee mousse for a special occasion or just to treat yourself to something sweet after dinner, you’ll love how easy it is to make ahead of time and how tasty it remains even after being stored and reheated.

Tips for Perfect Results

“Your morning coffee, upgraded to a luxurious dessert.”

Now that you have all the ingredients ready for the Irish Coffee Mousse, here are some tips to ensure you get perfect, delicious results:

1. Use high-quality coffee

The flavor of the coffee is an essential ingredient in this recipe, so it’s essential to use a high-quality coffee. We recommend using freshly brewed and strong espresso or coffee. If you don’t have access to this type of coffee, instant espresso powder can be used.

2. Ensure the gelatin dissolves

Make sure the gelatin is completely dissolved by sprinkling it evenly over cold water or any other liquid specified in the recipe. Set it aside for a few minutes, then stir continuously until there are no lumps left and the gelatin has completely dissolved.

3. Whip the whipping cream to soft peaks

Take care not to over-whip the whipping cream; you want it to reach soft peaks, but if you go too far and make it too firm, the mousse will not be as light and fluffy as it should be.

4. Use the right bowl size

When whisking together your egg yolks and sugar, make sure to use a heatproof bowl large enough to later add in your coffee and whipped cream.

5. Keep everything cold

Allowing your ingredients to get warm will make everything more challenging to work with when making the mousse recipe – so make sure everything stays cold until needed.

6. Work slowly and steadily with chocolate

While melting chocolate for this recipe or creating the felted chocolates that’ll decorate your mousse atop, it’s essential to work slowly and steadily because chocolate can quickly scorch or seize at high temperatures.

Now that you know these tips – why not give Irish Coffee Mousse a try? It’s not overly complicated – as long as you follow these tips – and we’re confident you’ll love it as much as we do!
