Preheat the oven to 180ºc/160ºc fan and grab two ramekins/creme brûlée dishes
Melt the butter, and add in the sugar and mix
Add the egg and the vanilla extract and mix well again.
Add the flour, bicarbonate, cocoa powder and chocolate chips and mix well until it comes together to form a lovely thick cookie dough
Divide the mixture into two dishes and bake the cookie dough in the oven for 12-15 minutes or until dry on top and just cooked through in the middle – the gooier the better!
Remove from the oven and let it cool for a couple of minutes and then serve with a giant dollop of ice cream!
