"choco mousse"

Welcome to my leftover chocolate mousse recipe.

I don’t know about you but I hate food waste. I mean I really hate food waste. I used to watch these frugal family TV programmes and it would usually involve them inspecting the bin and telling off the guests on the show about how much they were wasting that was never get eaten.

I suppose you could say this was us once upon a time. We would order too many takeaways because we were too lazy to actually cook and then the food we had originally planned to eat would end up in the bin.

Even when we tried our hardest to completely get rid of our food waste problem we never really completely solved it.

We would often want lettuce in our wraps but still end up with half a lettuce never used.

So our solution was clearly to stop buying lettuce apart from in summer when we would make good use out of it.

We keep an eye on sell by dates on our food and nowadays the only food waste we seem to have is when we buy strawberries and you open the packet and a couple have gone off.

But there is not a lot I can do about this and I am not willing to quit strawberries!!!

So when I was planning a vanilla ice cream recipe for a future blog post that required loads of egg yolks, I was suddenly left with a fridge full of egg whites.

So it was only natural that I would make a big batch of chocolate mousse to go with them.

I am clearly only doing this to help the planet and it has nothing to do with the fact that Dominic’s chocolate mousse is absolutely awesome!

How Frugal Is Chocolate Mousse?

Our chocolate mousse recipe works out at 2,59€ for a family of four or 0,65€ each. Or if you are based in America then this is just $0.72 per mouth that you have to feed!

  • Whip the egg whites with an electric whisk (otherwise by hand it will take hours) and when you have stiff peaks add the sugar.
  • Crush up your biscuits and mix them into your liquid.
  • Slowly add your melted chocolate and whisk it all together until it resembles a nice creamy mousse.
  • Fridge for two hours and serve.


You can also freeze your chocolate mousse into chocolate moulds for little snacks for later. This is particularly good if like me you have excessive egg whites to use up!
This recipe is of course based on lots of leftovers so you could change it to match whatever you have in your fridge or cupboard.

  1. Two things: why are there comas in Euros, and who has leftover chocolate anything? It’s only chocolate you haven’t had time to eat yet. Saying that, this sounds pretty good. It’s textured, right? because of the cookies. I’ve never had textured mousse.

    • Hi Jean,

      No idea why they put a comma in Euros they have always done that! They also put the sign after the amount and I grow up on the £ where the symbol was before. I think Belguim likes to be different when they put the Euro together 🙂

      This recipe was actually when I had loads of chocolate in and needed to use it up before we went on holiday. But it is unusual for us to have leftover chocolate 🙂 yes it is lovely and textured and tastes amazing. I just want to eat it now with all the talk about it 🙂
