Moist Chocolate Cake – Moelleux au Chocolat

A recipe that in Belgium every chocolate lover knows by heart is the one for the famous “Moelleux au Chocolat” from the cookbook “La cuisine à quatre mains”.

Even my husband who usually leaves patisserie to me, knows this one by heart and makes it on his own if the mood strikes!

Ironically the same recipe that is described in the Belgian cookbook is the one of his beloved grandmother so it is a sure guarantee that the cake is melt in the mouth delightful!!!

We generally eat it warm, together with my homemade Sorbet which perfectly balances the sweetness of the cake!


  • 200 g butter
  • 200 g sugar (although I personally use 170g)
  • 200 g dark chocolate (I use 72%)
  • 5 eggs, separated
  • 1 handful of flour (~ 50 g)
  • my personal touch is to add 1/2 tsp of salt and 1 tsp vanilla

In a pan melt the butter over medium heat. Halfway through add the chocolate broken in chunks and switch off the heat. This method will cool down the butter slightly and is a perfect way to lessen the electricity use. Please don’t do it the other way round as butter takes more time to melt than the chocolate.

Beat the eggwhites until they form a peak.

In another bowl mix the egg yolks, salt, vanilla and the sugar for about 2 minutes. Add the butter-chocolate mix. Gently fold in the egg whites and then the flour. Please don’t overmix.

Pour the dough into a round mould and bake for 40 minutes at 150C.

The cake is supposed to be moist on the inside.

Serve warm, barely out of the oven, with Ice Cream or Sorbet.

  1. Caroline I made this cake yesterday for my father in law in hospital for past 10 days and eating just hospital food. Une tuerie, he wanted us to leave so that he could finish off the slice I brought when visiting. I will certainly be making this again. It was so fondant, hard to cut but but maybe because still warm, I put less sugar than you mentioned, I will certainly be making it again. I have many chocolate lovers in my circle of friends. Thanks it’s so simple to make. Hope you had a lovely break away, you are just formidable and so organized, I could take lessons 😆 cheers, Angela xx

    1. I am soo glad that your father in law enjoyed the cake! Thank you very much indeed for your charming words. You are a lovely daughter in law 😍. When I make this cake in France I always cut down the sugar as I really have a hard time finding chocolate of 70%. So I use the Nestlé Patisserie which already contains quite a lot of sugar as it has only 54%. Well done you for making your father in law happy!

  2. Bonjour Caroline

    Encore une fois tu nous régales.
    J’ai aussitôt fait ta recette pour ne pas l’oublier car elle est ultra simple et rapide à faire.
    C’est trop bon.
    Mon mari adore le moelleux.
    Mon fils mangera le reste demain.

    J’ai transmis cette recette à ma fille en Australie car c’est une dingue de pâtisserie et chocolat.

    Merci pour toutes tes délicieuses recettes
