Dark chocolate, eggs, a healthy portion of butter and a touch of sugar is all it takes to make Rachel Allen’s devilishly delicious mousse cake


1. Preheat the oven to 180C/160c fan/gas 4. Line the base of a 20 cm diameter spring-from/loose bottomed cake tin with a disc of baking parchment and grease the sides with butter.

2. Place the chocolate and butter in a heatproof bowl set over a saucepan of simmering water and allow to melt, then remove from the heat and set aside.

3. Place the eggs and sugar in a separate bowl and, using a hand-held electric beater or electric mixer, whisk for 7–10 minutes or until the mixture forms a light, pale mousse.

4. Fold the chocolate mixture into the eggs until fully combined, then pour into the prepared tin and bake for 20–22 minutes or until the cake is almost set. Allow to cool down completely in the tin before removing, then dust with cocoa powder and cut into slices to serve.

Made this today confused over the two cooking times shown ie 20/22 mins then 30 mins plus cooling time.......used initiative and took out of oven when I thought it was done. Very quick and easy to make loved the fact there was not too much sugar in recipe ...... it tasted delish.

what a wonderfully easy receipe, so light and moist, I never had a 20cm cake tin so I lined a small cast fry pan and flipped it over when it was cold, it still turned out, thank you Rachel I must buy your book. I wanted to click on 5 stars but it would only let me do 1, so not fair, it's is a 5

Used a multicooker Redmond RMC-M70 to make this cake. I had only 4 eggs to use for it tho, but in the end I would say it turned out so tasty. I am happy that I found this recipe, thank you for sharing!

Made this exactly as described last night and it was perfect and absolutely delicious

HelenB482 HelenB482 Posted 17 Nov 2014 8:08 AM

I just made this exactly has described in the recipe and it didn't cook???? The outside was cake like but the middle was just the chocolate runny. So disappointed. Please advise what this may have been from. Recipe says to cook for 20 22 minutes and I even did it a bit longer as didn't look right.

Hi Hina, thanks for your comment - as with most recipes, use medium eggs unless otherwise stated. I have made this cake many times and it's one of my favourites!

Anna -Good Food Anna -Good Food Posted 30 Jan 2014 9:57 AM

What size eggs do we use in this cake?

HinaT38222 HinaT38222 Posted 29 Jan 2014 6:59 PM

I have now made this a couple of times.Both times they slightly dipped in the centre. Use the dip to put fresh raspberries that have been frosted in, Looks, and tastes heavenly :-)

I made this cake but it sank in the middle. I followed the recipe exacly but on reading some of the other comments I didn`t use unsalted butter - maybe that made the differance. It was absolutely lovely and we ate it with cream - very rich.

frenchtart frenchtart Posted 14 Apr 2013 7:42 PM

Sounds almost too easy...but will give it a go, Rachel Allen's recipes are always yum!

HildegardN77561 HildegardN77561 Posted 13 Apr 2013 8:08 AM

Absolutely love this recipe, so easy and tastes so great. Tastes even more spectacular the next day.

Hi Ken, thanks for your comment - this is one of my favourite cakes so I'm happy to help with a few tips. First, I whisk the egg and sugar mixture with an electric whisk at a high speed for the full 10 minutes, until it becomes mousse-like and fills the whole bowl. As you fold the chocolate in, be very gentle and try not to stir it or you will end up knocking the air out of the mixture, which may be causing a thicker, doughier cake. But please bear in mind that this cake, like many flourless cakes, will have a thicker consistency - it's somewheer between a torte and a cake.

Hope this helps.


Anna -Good Food Anna -Good Food Posted 19 Feb 2013 10:02 AM

Iv made this twice and both times the bottom of it was doughy. I think I'm following recipe. Have you any tips

KenF2590 KenF2590 Posted 15 Feb 2013 7:59 PM

Hi Sareena, thanks for your comment - generally for baking, it's best to use unsalted butter so if it just says butter, it's safe to assume unsalted.

This is one of my favourite cake recipes so I hope you can try it; I have actually made this with unsalted and salted buttet and it's turned out well every time.

The secret is to make sure you get your eggs really mousse-like at the beginning, I always whisk the mixture for the full 10 minutes.


Anna -Good Food Anna -Good Food Posted 04 Feb 2013 3:17 PM

Hi Rachel regarding one the butter you use for this recipe is it unsalted butter? in some of your other recipe that you have used butter it isn't mentioned if its unsalted butter or just ok to use normal butter?

Sareena Sareena Posted 02 Feb 2013 10:43 AM

Very easy to make, made just a little change... I used half dark and half milk chocolate.

Good result! :-)

GabiB22928 GabiB22928 Posted 30 Sep 2012 10:38 AM

I had the same issues with time and flavor.

1. I changed the recipe a little to increase the size.
2. The time to cook was, inside the oven: 47min (on) and 10min (off)
3. Next time I will do it with milk choc.

But this recipe is really easy and the result is very good.

Just made this with my little girl, really easy and fun to make but on tasting I found it a bit too bitter?
As we don't normally bake we wondered if I could substitute soe of the dark chocolate for milk choc?
We also had it with strawberries and cream which all looked great together

I made this for a birthday in the office; it was so easy to make and went down so well - I would make this again and again!

Anna -Good Food Anna -Good Food Posted 25 Apr 2012 9:18 AM

I made this for a dinner party, mixed cocoa powder with icing sugar to sprinle on the top, served with strawberries and pouring cream. This was the best desert I have EVER made. Took a little longer than stated to cook (but I think thats my oven). would HIGHLY RECOMMEND!!
