I found this recipe somewhere on the internet several years ago when I was having a craving, possibly pregnancy-induced, for something exactly fitting this description. It's still a real winner.
Giant Chewy Chocolate Chip Cookies
1 ½ sticks unsalted butter
1 c brown sugar
½ c granulated sugar
1 large egg and 1 egg yolk
2 tsp artificial vanilla extract
½ tsp baking soda
½ tsp salt
2 c + 2 tbsp all-purpose flour
1 ½ c semi-sweet chocolate chips
Preheat oven to 325ºF. Melt butter completely in the microwave. Let cool. Add both sugars, vanilla and eggs to the butter. Mix thoroughly. Blend in salt and baking soda. One cup at a time, add the flour and mix until smooth. Feel free to add a small amount more of flour if you even remotely think the dough could use it. It won’t hurt. Mix in the chocolate chips until evenly distributed. Scoop generous 1/4 cup mounds onto cookie sheet. I find 6 fit well and allow room to flatten a bit. Bake for 15-20 minutes, depending on your oven. They are done when slightly golden, but not brown on the bottoms. Cool for a few minutes on cookie sheet, and then let cool completely on a rack.
Shelf life is irrelevent since they will all be eaten sooner than they should :)
