Magic Two-Ingredient Chocolate Mousse

Two-Ingredient Chocolate Mousse {Katie at the Kitchen Door}

This incredible chocolate mousse has only two ingredients – chocolate and water – with a deep chocolate taste and a smooth, fluffy texture.

Recipe by Heston Blumenthal via Eat Live Run.

Note: this recipes is all about the chocolate you use, so use the good stuff. If you don’t love the flavor of the chocolate, you won’t love the flavor of the mousse. If the mousse becomes grainy as you whip it, return it to the heat and re-melt, then try again.


  • 4.5 oz of bittersweet chocolate chips or roughly chopped chocolate, the best you can afford
  • 1/2 cup water
  • ice


  1. Fill a large metal bowl with ice and cold water and set aside.
  2. Place the chopped chocolate and the water in a metal bowl. Bring a small pot of water to a simmer – the bowl should fit snugly on top of the pot without the bottom of the bowl touching the top of the water. Place the metal bowl over the simmering water and melt the chocolate, stirring continuously with a rubber spatula. The water should get incorporated into the chocolate as you stir. As soon as the chocolate mixture is smooth and fully melted, remove it from the heat. Place the bowl with the chocolate in the bowl with the ice water, and whisk the chocolate constantly for 2 to 3 minutes, until the chocolate has thickened slightly and the color has become a bit more pale.
  3. Divide the mousse into 2 wine glasses or ramekins and chill for at least 30 minutes, then serve.
