Flourless Chocolate Cake with Salted Caramel Mousse

In what other way to celebrate the first fragile signs of Spring than with another delicious treat with chocolate, like this Flourless Chocolate Cake with Salted Caramel Mousse ?

I have been very enthusiastic of the idea to participate to this month Chocolate Party hosted by Roxana from Roxana’s Home Baking.  The theme for this month is chocolate and caramel, which for me was pretty challenging.
Finally I have decided what to do for this event, a flourless chocolate cake for the base topped with a salted caramel mousse on top decorated with chocolate curls and caramel swirls. Sounds great, looks great and tastes divine. Didn’t last too long after the photo shoot 🙂 that’s for sure.

Flourless Cake

  • 1 stick (110g) butter
  • 4 eggs
  • 1/3 cup (70g) sugar
  • 1 tbsp (8g) unsweetened cocoa powder
  • 5 ounces (150g) bittersweet chocolate
  • Pinch of salt

Caramel Mousse

  • 1/4 cup (50g) sugar
  • 1 tbsp (15ml) water
  • 1 tbsp (14g) butter , at room temperature
  • 1/4 tsp (1g) salt
  • 1 tbsp (8g) cornstarch
  • 1 tbsp (15ml) water
  • 1 cup (240g) heavy cream , divided
  • 1/2 tsp (3g) vanilla been paste or vanilla extract

Optional -Chocolate Curls

  • 3/4 cup (90g) semisweet chocolate

Optional-Caramel Swirls

  • 1/2 cup (100g) sugar
  • 2 tbsp (30ml) water
  • 1 tbsp (15ml) lemon juice


  • Line a 9-inch(23 cm) springform pan(with a removable base) with parchment paper. Separate egg yolks from whites. Preheat oven to 180°C (350°F). 
  • Melt chocolate and butter over a bain-marie until smooth. Add  yolks one at a time and stir well. Add cocoa powder and salt.  
  • Whip egg whites until foamy with a mixer, gradually add sugar.  Gently fold the whipped whites to chocolate mixture . Pour batter into prepared pan and bake for 25-30  minutes.
  • While the cake is baking you can prepare the chocolate curls. (I have tried to use some indications from "The Pioneer Woman")  Melt chocolate over a bain-marie until smooth. Pour the chocolate on the back of a baking sheet. Using a spatula or knife spread the chocolate in a thin layer. Put the tray in the freezer for about 2-3 minutes. Whit a spatula begin to scrape the chocolate and helping with the other hand form curls of chocolate. (Mine are not perfect but were pretty ok for my first attempt. )
  • Prepare the Caramel Mousse. Heat 1/4 cup of the cream until it is hot and set aside. Combine cornstarch with water and set aside.  
  • Place the sugar and water in a medium heavy bottomed saucepan over medium-high heat, and cook without stirring until sugar dissolves and gets a caramel color. Remove the pan from the heat and add the hot cream and butter. It will bubble a little bit. Stir with a wooden spoon until smooth. Add cornstarch mixture and bring to boil. Cook until thick and bubbly for about 1 minute, stirring constantly.
  • Remove from heat, add vanilla extract and salt. Pour into a bowl, cover and refrigerate to chill.
  • Whip the remaining 3/4 cup cream. Fold 1/3 of whipped cream into caramel mixture and then fold in the remaining whipped cream.
  • Prepare caramel swirls. Place the sugar, water and lemon juice in a medium heavy bottomed saucepan over medium-high heat, and cook without stirring until sugar dissolves. Cover pan and cook 3 minutes. Remove lid and cook syrup, swirling the pan, for 3 to 4 minutes, until the syrup gets the color of dark caramel. Remove pan from heat, set aside to cool for 2-3 minutes, or until syrup begins to thicken. Using a fork, drizzle thin caramel over the back of a soup ladle. Remove from the ladle and repeat. If the caramel gets too hard heat again over very low heat and repeat the steps. 
  • Spread the mousse over the cake. Decorate with chocolate curls and caramel swirls if desire or simply with some grated chocolate or cocoa powder. Don't forget to check out all the other caramel chocolate recipes shared this month.

  7. jami Author says:

    Looks delicious – and might be a perfect Passover dessert if I swap the cornstarch for potato starch. What a treat!

    1. Ella-HomeCookingAdventure Author says:

      I have to try it without starch of any kind, It might work without too, I added just to make sure it will be ok 🙂 Is potato starch better?

    Oh yum this looks so good! I absolutely love the combination of chocolate and salted caramel!

  11. Allison Author says:

    Very very good. Made this tonight and it was a huge hit. I baked it in a 9″ pan and I think it would have been too thin in a 10″ pan. The thickness in a 9″ was perfect.

    1. Ella-HomeCookingAdventure Author says:

      I am so glad you liked it:) Yes, it is very good:) my family loved it too, my sister even made it for her husband's anniversary:) 

    2. Ella-HomeCookingAdventure Author says:

      You were right about the 9" pan,  didn't noticed then but the pan I used is about 10 on the top but around 9 on the bottom,  not straight form bottom to top. 

  12. Jane Author says:

    I tried making this and the cake came out amazing! But the caramel came out with a strange texture the first try. The best way I can think to describe it is like boogers. it all stuck together in one clump and pull away from the pan when I tried to stir. I thought it was probably because of the cornstarch so the second try I left it out. That time it came out really good in terms of taste, but when it was cooled, it was a bit too stiff to fold into the whipped cream easily. Any idea what could have gone wrong the first time and does it need to be totally cold when you mix with the cream?
    Thanks for the delicious recipe!

    1. Ella-HomeCookingAdventure Author says:

      Not sure exactly what the problem was, but is it possible that you let the sugar too much to caramelize? After it cools down it is a little harder, but after you add a part of whipped cream it easily combine with the rest. I wish I could be there to show you and make it with you.  It doesn't have to be too cold before folding it with the whipped cream, at room temperature is just fine. Let me know if you have any other questions, I would really love to help you with this as it is a delicious recipe. 

  13. Cedric Author says:

    This recipe looks really delicious , I’ll try it this week.

    Thank You 😉

    1. Ella-HomeCookingAdventure Author says:

      Yes.. it looks good and it really taste amazing. It is one of my favorite desserts. Let me know how it turns for you. 

  14. Barb Author says:

    Can this be made a day ahead of serving? I assume it should be stored in the refrigerator?

    1. Ella-HomeCookingAdventure Author says:

      Sure you can, actually this is what I did.. we served it after it was chilled overnight in the refrigerator.

  15. Luka Author says:

    Cake base looked perfect. Rose well with a nice colour, skewer pulled out clean and cake just starting to pull away from the sides of the pan. I took it straight out of the oven into room temperature, say 22 degree Celsius and took the spring form sides of after about 5 minutes. The cake eventually sank not only in the centre but all over to half the height that it originally came out of the oven. I opened the door of the oven to check for doneness at about 25 minutes and cooked it for a further 5 minutes. The cake taste was good and would love some baking tips on what could I have done wrong.

    1. Ella-HomeCookingAdventure Author says:

      I don't think you did anything wrong.. this is how it is suppose to happen.. it deflates. 

  16. Malin Author says:

    Hope to try this one as soon as I find a converter to the metric system! ????

  17. Natalie Author says:

    With the salted caramel mousse, would it be possible to pipe it into swirls? Will it hold its shape? Lovely recipe!

    1. Ella-HomeCookingAdventure Author says:

      Don't think so.. but you can try.. maybe refrigerate the frosting a bit before trying to create the swirls and might work well
