Method

Heat the oven to 180°C. Tip the butter and sugar into a bowl, beat until combined, then stir in the yolks and vanilla. Tip in the flour, baking powder, chocolate chips, a pinch of sea salt and any other fillings you want to add. Mix until a crumbly dough forms. Lightly butter a frying pan. Spoon in and flatten the cookie mixture. For a gooey dessert, bake for 20 minutes, leave to rest for five minutes, then scoop straight from the pan and serve with ice cream.
