Hot chocolate mousse recipe

I tried another great recipe for the slow cooker last night, and it turned out to be the perfect way to use up part of the mountain of chocolate we still have sitting around after Christmas (providing endless temptation when we are supposed to be on a healthy eating regime). This chocolate mousse recipe comes from my BBC GoodFood slow cooker book and is an ideal winter take on the classic chocolate mousse, as it’s served hot. It can be done either as individual desserts, or as one big one that you can all grab a spoon and dip into. I’ll explain how to do both.

You will need
– 2 x 58g Mars Bars (I used a Mars Bar, Milky Way and assorted other Christmas chocolate)
– 100g bar of dark chocolate
– 50ml milk
– 3 egg whites

Step 1
Break the chocolate into pieces and put it into a heavy-bottomed pan with the milk. If you’re doing one big mousse, you can use the slow cooker pot, as I am here. Heat gently and stir constantly.


Step 2
The chocolate will soon melt and form a glistening, smooth mixture. Take it off the heat and cool for 15 minutes, stirring regularly with the whisk.


Step 3
Whisk the egg whites til they form soft peaks. When the chocolate has cooled, fold in a quarter of the egg whites using a metal spoon. Then fold the rest in.


Step 4
It will look like this when you’ve finished folding in the egg whites. If you’re using individual pots, decant the mixture into them now, cover them with a dome of foil each and put them into your slow cooker pot. Fill with boiling water around the pots until it goes half way up the sides of them and then cook the mousses for an hour in their bath, on the high setting.

If, like me, you are doing one big pot, simply put the slow cooker pot into the slow cooker and heat on the high setting for an hour.


Step 5
This is what mine looked like after being cooked for an hour. A little odd. The mixture was bubbly because of the egg whites and they have all burst (the mixture also deflated quite a bit when I took it off the heat), so I’m not sure whether I overcooked the mixture or what. It still tasted awesome, even if it looks a bit peculiar! I might try cooking it for less time next time.


Step 6
I served the mousse out into bowls, and as you can see, it’s perfectly cooked. I can confirm that it tasted really great and was a nice easy dessert for a cold night!

    The chocolate recipe looks really tempting but with a wedding coming up think I had better give it a miss. Xx

    I wish all recipe books showed part finished photos ( in addition to the final outcome finished dish !) as you have done Rachel.

      Thanks Stuart, me too! I always think it’s useful to know what different stages look like, so it’s good to know I’m not the only one! :)
