Preheat oven to 350°F/180°C and line an 8 inch cake pan
Whisk together the eggs and sugar until thick and pale
Melt the butter and chocolate together in the microwave in 30 second bursts until totally melted, pour into the egg/sugar mixture and stir until combined
Stir in the flour, ground almonds, salt and cocoa powder. It's fine to keep using the whisk!
Pour into the cake pan and spread the top to be level. Bake for 40 minutes or until a skewer inserted in the middle comes out with moist crumbs (not clean, but not covered in batter)
Allow to cool completely and then put into the fridge for at least 3 hours before serving
Once ready to serve, remove from the pan and dust with cocoa powder or icing sugar
Notes
Gluten-Free Option: You can easily make this chocolate torte gluten-free by leaving out the flour and doubling the ground almonds.
