Chocolate Coffee Mousse Dessert with a spoon

I dreamt up the idea for this chocolate coffee mousse cake dessert while at a party with a close friend. We were both noshing on some mousse when she mentioned how great it would be if there were a layer of spongecake included. I loved the idea and decided to take it back to my kitchen and start demoing. The end result? These adorable little parfaits with layers of rich coffee and liqueur-infused mousse and sweet cream-soaked sponge cake. You’re going to just love them!

Note: You’re going to need to prepare a sponge cake for this recipe. To cut down on day-of prep, make it a day in advance.

How to Prepare Coffee Mousse Cake Dessert

Preparing this coffee mousse cake dessert requires under 10 ingredients and some light assembly. Below, find a rundown of the recipe instructions before you dive in.

  • Make a Sponge Cake: Bake a sponge cake on a sheet cake pan in the oven. After it cools, use the rim of your dessert cup to cut out even-sized circular rounds. 
  • Soak the Sponge Cake: Place a sponge cake round in the bottom of each dessert cup. In a large bowl, combine the heavy whipping cream with the Bailey’s and pour a spoonful of the sweet cream on top of each round of cake. 
  • Make the Mousse: In a large bowl, combine the chocolate chips, coffee, butter, and second portion of Bailey’s. Microwave and whisk until smooth. In a small bowl, combine a bit of heavy cream with the gelatin powder and allow it to sit for 5 minutes. Next, microwave the gelatin mixture for a couple of seconds. Add the gelatin mixture to the chocolate mixture and stir to combine. Finally, beat the remaining heavy whipping cream with an electric mixer on medium speed until you get stiff peaks. Stir half of the whipped cream into the chocolate and fold the other half in with a spatula.
  • Assemble the Coffee Mousse Cake: Place the mousse in a piping bag and pipe equal amounts on top of each sponge cake round. Optionally, top it with another sponge cake layer, followed by another mousse layer. Garnish the parfaits with chocolate shavings and cocoa powder. Enjoy! 

Hot Tip: Instead of brewing an entire batch of coffee for this recipe, use instant coffee or instant espresso powder to make the 3 ounces you need for this recipe.

5 Top Tips for Making Coffee Mousse Cake 

Here you’ll find our top 5 tips to help you nail this coffee mousse cake dessert on the first try. 

  • Allow the sponge cake to soak. Allowing the sponge cake rounds to soak in the liqueur-infused cream while you prep the mousse is key. This will make the layers ultra-moist, while also adding a punch of flavor.
  • Don’t overmix the whipped cream. If you overmix the whipped cream, it will turn into butter. Once you get stiff peaks, immediately stop mixing to avoid this.
  • Don’t overmix the mousse. Avoid the urge to over incorporate the whipped cream into the melted chocolate mixture. If you stir it too aggressively, you’ll lose the fluffiness of the whipped cream and your mousse will fall flat. 
  • Use a piping bag for the best presentation. Instead of spooning the mousse into each dessert cup, pipe it with a pastry bag. This will help aerate the mousse and keep it nice and fluffy.
  • Swap in your favorite liqueur. if you’re not a fan of Bailey’s or just don’t have any on hand, swap in your favorite liqueur instead. You can’t go wrong! 
  • Keep the coffee mousse cake refrigerated before serving. To prevent the mousse from deflating at room temperature, keep the coffee mousse cake dessert cups in the fridge until you’re ready to serve them.

Hot Tip: Swap the semi-sweet chocolate chips out for dark chocolate chips or even white chocolate chips depending on your preference.

FAQ

Why is it called mousse?

The word “mousse” is a French word for “froth” or “foam”. This references the dessert’s super airy and fluffy texture.

Does this coffee mousse cake contain caffeine?

Technically, this coffee mouse cake contains just a bit of caffeine from the added coffee and Bailey’s liqueur. That said, it’s such a minuscule amount that it’s unlikely you’ll get a buzz from eating a serving.

Can you make this recipe as a standard cake instead?

If you’d prefer to do a large cake round versus individual parfaits, go for it. Make the sponge cake in a sheet pan and slice it into two evenly-sized square layers. Then, alternate the cake layers with the mousse and allow the cake to set in the refrigerator for a couple of hours before you plan to serve it.

Can you use Kahlua liqueur instead of Bailey’s?

Kahlua liqueur is a perfectly acceptable alternative to Bailey’s. While it’s not creamy like Bailey’s, it will add the same kick of coffee flavor to the mousse.

Can you omit the liqueur all together?

Yes, it’s acceptable to omit the liqueur all together. To keep the coffee flavor strong, swap in equal parts of more coffee in its place.
