Honeycomb Chocolate Mousse

Chocolate Honeycomb Mousse

This is the first recipe I made from Leon Baking & Puddings. You can read my review of the book here. It’s a simple chocolate mousse but I jazzed it up by adding shards of homemade honeycomb. What’s great about this recipe is that’s it’s also  easily adapted to be dairy free.

Chocolate Honeycomb Mousse

The recipe calls for egg whites which keeps the mousse light and airy. A shot of espresso enhances the chocolate. Alex has already requested another batch. Next time I would make half of the honeycomb recipe. It made a huge portion and was much more than we could eat in a few days.

Yield: 4 servings


Chocolate Mousse

100g 70% chocolate

30g unsalted butter

2 egg yolks

1 shot espresso

zest of 1 orange (optional)

3 egg whites

20g caster sugar


100g unsalted butter

1 tbs white wine vinegar

300ml golden syrup

400g caster sugar

1 tsp baking soda


  1. Make the chocolate mousse. Get 4 containers ready. In a microwave safe bowl melt the chocolate and butter at 30 second bursts. Whisk the egg yolks and caster sugar in small bowl until nearly white and stir into the melted chocolate. Stir in the espresso and orange zest.
  2. In a separate bowl whisk the egg whites to stiff peaks and then fold into the chocolate mixture. Pour into the serving containers and refrigerate until set.
  3. Make the honeycomb. Use a heavy bottomed pan as the mixture will bubble up significantly. Butter a large baking dish and line with parchment paper.
  4. Over a low heat melt the butter. Add the vinegar, golden syrup and caster sugar. Turn the heat up to medium and don't stir the pot.
  5. Insert a sugar thermometer and heat until the syrup reaches 149 C. Remove from the heat and stir in the baking soda. It will bubble up like crazy. Pour into the lined baking dish. Once the mixture has started to set score into bite sized pieces. Once cooled break into pieces and place on top of the mousse before serving.

  1. This looks so good! I don’t have a sugar thermometer, is there any way of telling when the sugar has reached 149c?

    • I don’t think so but I’m not 100% sure. A thermometer would be the most accurate way to go. They only cost a couple quid. I got a cool digital spatula that reads temperature.

    That does sound cool. I”m in south africa, but I should be able to find one somewhere here :) thanks!

  3. Mmm mousse, I love mousse so much! I have barely used my Leon book and I really must because it’s so jam packed with things I’d meant to try and a joy to read.

    Good choice of letter H – I have been stumped!!

    Yeah, there is not another way to tell when the sugar has reached 149’C. Your recipes are lovely !
    Thanks for sharing…(:

  5. The mousse looks gorgeous – and it would never have occured to me to make honeycomb! Was it hard? It looks like it turned out really well. Thanks for entering it into Alphabakes!

  6. Thanks for entering this to AlphaBakes – 2 of my favourites – chocolate mousse and honeycomb! I’ve never made honeycomb and was planning to for this month’s challenge but decided on something else instead.
