In case you've been living in the dark as I was until recently, allow me to
inform you change your life with the stunning revelation that you can make cookies on the grill. Now what are you waiting for?
You can use this method with pretty much any cookie recipe. Choose a recipe and heat your grill, covered, to whatever temperature your recipe calls for. (I find that most call for 350 degrees. On my gas grill, having the burners all set at medium does the trick, but a thermometer is a good idea if you have one.) Place the cookie dough on a sheet of foil on the grill grate, then cover, watch, and wait until they're done. The bottoms will cook faster than they do in an oven since all the heat is coming from below, so the cookies get nice crisp bottoms and are still soft and gooey on the inside. Works for me. Now get to it.
