Dense flourless chocolate and coffee cake

This gluten-free chocolate cake is rich and dense  and you only really need a small slice that’s of course,  if you can resist!

What you’ll need:

• 400g good-quality dark chocolate
• 320g light brown sugar
• 260g butter
• 5 large eggs, separated
• Espresso shot (optional)

What you’ll need to do: 

1. Melt the butter and chocolate together in a bowl set over a saucepan of previously boiled simmering water.
2. Allow the mixture to cool and stir in the sugar and egg yolks, stirring swiftly so the yolks don’t set. Add the coffee at this stage if using.
3. Fold in the egg whites slowly until they are fully incorporated.
4. Pour into cake pan and bake for about an hour until the outside is set and cracked in the middle.
5. Unfortunately, this cake is too dense for a wooden skewer test. The cake should look firm but with a very slight jiggle.
