This Flourless Chocolate Cake with Coffee Mousse is one of my favorite decadent cakes that I’ve been wanting to share with you for quite some time. The flourless chocolate cake at the base is rich, chocolaty, dense and fudgy while the coffee mousse on top is full of aroma, soft and airy. Chocolate and coffee have always made such a great pair and in this form it is absolutely heavenly. This is by far a rich cake for chocolate lovers, who will start to love chocolate even more from now on.
The recipe is easy to prepare and you don’t need too many ingredients to make this unforgettable dessert. Even if this was not made on-purpose it is a gluten-free dessert, which makes it great even for those who have gluten intolerance. Try this recipe as soon as possible, it is a must for this year 🙂

Thank you so much for this wonderfully decadent recipe. I made this today and it came out perfect! Definitely a crowd pleaser!
I am so glad you liked it too:) one of the best in my opinion
When mixing the egg yolk, cornstarch, and milk mixture in the saucepan over low heat for the mousse, how long does that take for the mixture to become thick?
Hello Ella can dark chocolate be used instead of semi sweet chocolate..??
Tried this recipe and it came out stunning!!! Thanks a lot for sharing this recipe and using simple ingredients and doable methods. Also, love the presentation of your videos, truly an art in itself.
Am facut prajitura asta de Paste si a iesit perfect! Nu e prea dulce, blatul dens si plin de ciocolata merge perfect in combinatie cu mousse-ul pufos. Nu sunt o fana a prajiturilor cu aroma de cafea pentru ca nu obisnuiesc sa beau, dar asta chiar mi-a placut. Cu siguranta o voi reface. Toata lumea a fost incantata! Multumim pentru reteta. 🙂
Ma bucur tare mult sa aud asta Sarah 🙂 Scuze pt raspunsul cu intarziere.. sper ca o sa incerci si alte retete
Hello Ella would love to try this. Can milk chocolate be used instead of semi sweet chocolate
yes.. but you get better results with semisweet chocolate
is there any replacement for cornstarch ?
yes.. use same amount of flour
yes.. use same amount of flour
First thank you for an easy and great recipe. However I have some problem making this cake. My cake didnt turn out as moist as yours but dry on the surface and deflated badly on a cooling rack. Also my mouse is not as thick as yours. Its kind of runny. I have attached the pics. Can you help me out? I did make sure to have all correct measurements. Am I over folding the battle? Oh I just figure out I can not add pics here.
Hello Ella want to try the coffee mousse but can I go with this instead of adding whipped cream or gelatine. Just gently folding in 2 cups of thick (not whipped) cream and then pouring the mousse in shot glasses. Would the taste differ or what.. please reply..??
Hello! My older sister has been begging me to make her a chocolate mousse cake, so i decided to try out this recipe. Can i substitute the instant coffee for cocoa powder to make a chocolate mousse instead? :)?

Is this recipe gluten free?
This recipe is so amazing – flourless cake with coffee mousse! I made it yesterday, and it became very delicious! Thanks for the recipe!
hi ella, is there a reason for not using baking powder? in most of my recipes I use it. plus my batter came a little liquidy…
This cake is seriously SO amazing. For some reason every time I make it it deflates a bit in the middle when it comes out of the oven. But I just add the coffee mousse and it still looks amazing and tastes amazing. I made it for my class and it was gone within 30 minutes.
mi piacerebbe ci fosse la trduzione in ITALIANO.
I have made the flourless cake many times and is always a hit with friends & family.
Taste amazing. but my cake base seems to be larger than the mousse layer.
Also the cake batter is runny then yours. Any tips ?
Which ever way it is delicious …….
possibly the best desert i’ve ever made….wow.
THIS WAS A PIECE OF HEAVEN! LOVED IT!
My gluten intolerant family adore it. Only problem is that my cake tins or 24 or 26cm. Could you tell me how to adjust quantities accordingly. When I try it comes out “hit and miss?” Can you help
You can always use the rule of three , from math, to find the correct measurement.
Can I swap out the instant coffee with cocoa powder to make chocolate mousse?
Yes, you can.
Can I replace instant coffee with esspresso ?
Yes, you can
Can I leave out the gelatin?
Buna, Ella! Te-am descoperit din intamplare si marturisesc ca acum este singura mea sursa de inspiratie cand vine vorba de prajituri pentru orice aniversare, petrecere, sarbatoare si chiar si comanda 🙂 Sunt retete perfecte si fara secrete ascunse care sa “te ajute” sa nu iasa. Urmatoarea prajitura depe lista este aceasta. Am o intgrebare: Pot folosi toate ingredientele in cantitate dubla, dar sa le pun in aceeasi tava, de 20 de cm? Vreau sa iasa mai inalt tortuletul. Multumesc mult si spor la treaba! 🙂
I tried this cake recently and I loved the coffee mousse, but the cake base had a strange taste to it and was pretty dense. Do you have any idea what the problem might be?
It was a WOW I impressed all my family gathering, I mean all.
I 150% recommended it! Easy to make and so elegant and full of flavors.
You made me look like a pro once again.
Thank you ??
Yes:) this is one of the best cakes on my blog:) So glad you tried this out.
This dessert was devine! All my guests raved about it!
There are quite a few steps to make the coffee mousse and the flourless cake but its worth it in the end because it all came together so well.
I used nescafe gold instant coffee granules and found that adding an extra tablespoon did the trick in bringing out the coffee flavour.
Thank you for posting this recipe with an easy to follow video.
This is the second dessert recipe i’ve tried from this page and I cant wait to try more.
This is the first recipe I tried from this site and it is wooooow! All my friends would kill for a piece of it. A few years ago (4 or 5), I baked it for one of my friends for his birthday to share it with his team, but he got another one as well from a fan of the team. And my friend said about this coffee cake: “this is soooooo good that only royalty deserves to eat from it!” and I think this sums it all up. Thank you for the recipe, Ella!
