This is not just a chocolate cake. This is a liquid chocolate cake with a brownie-like shiny and crinkled top, giving way to a centre that is quite literally oozing gooey melted chocolate.
Pre-heat the oven at 180°C. Grease an 8 inch baking tin with melted butter/oil and set aside.
Melt the butter and chocolate over a double boiler (place a heat proof bowl with these ingredients on top of simmering water). Take off the heat once melted.
Sieve the salt, cornstarch and the cocoa powder in a separate bowl.
Whisk the eggs and sugar until they begin to look pale (This is what gives the cake it’s flaky crust!)
Once warm, whisk in the butter and chocolate mixture with the eggs.
Add all the dry ingredients, and kahlua/rum (optional) into the mix, gently folding it in.
Pour into the greased tin and bake at 180°C for 10-12 minutes or until the surface begins to set! Allow to cool for 5 minutes, serve warm.
