The lone-dweller, in need of the balm that only a freshly baked cookie can provide, is faced with a most unsatisfactory choice: do without or make a batch big enough to keep a huge hungry household happy. I had to put that right, and not just out of altruism, you understand.
To this end, I have created a cookie recipe that answers my every requirement: deeply chocolatey, sweet but not too sweet, and sprinkled with flaky sea salt. They are the work of an easy moment, requiring no more than a couple of bowls, a wooden spoon and a spot of stirring. And while I urge you to eat one—if such urging is even necessary—when it’s still warm, so that it’s crisp around the edges, its center tender and shortbready and gloriously gooey with nuggets of molten chocolate, you can for a contrasting kind of eating enjoyment leave the other until the next day (but no longer), when it will be slightly sandy and softly chewy. But these are big old cookies so, if you find yourself in company—and a generous mood—you can graciously offer one of them without feeling short-changed.
Since there is no egg involved, it is a simple enough matter to veganize these: just replace the butter with the kind of margarine that comes not in a container, but in a block, manufactured specifically for baking. I’ve tried making them with coconut oil, which would be a more wholesome substitute, but I’m afraid it just doesn’t work. Bittersweet chocolate should always be dairy-free, but do check the package of chocolate chips to make sure. While you can make these gluten-free, you will have to let them get cold before eating them (or they won’t hold together) thus forgoing the goo, but enjoying them rather as tender chocolate shortbread.
