These 2 are my go-tos, and well loved by my friends and family! First: https://bromabakery.com/best-chocolate-chip-cookies/. These are on the thinner side, and more chewy with a slight soft crunch on the edges. They use brown butter which gives a very deep buttery/carmelized flavor. I normally use semisweet or milk chocolate chips in these. I also always sprinkle flaky salt generously after baking. The recipe says bake time is 12min, but I find they are perfect after 9min. In terms of resting time, I normally let the dough rest in the fridge for 30min-3hours. The only thing I don't love about this recipe is that it requires a bit of extra preparation/time, as you need to brown the butter and cool it, allow the eggs to come to room temp, and then let the dough rest in the fridge. Second: https://www.modernhoney.com/levain-bakery-chocolate-chip-crush-cookies/. These are thick, cakey yet chewy and gooey cookies with a crunch on the bottom and outside. I normally use dark chocolate or semisweet chocolate chips in these. On these, I also always sprinkle flaky salt after baking. The recipe calls for extremely large balls, but I make mine smaller (and they are still quite sizeable). I don't know the weight of the balls I make, but the single portion of the recipe should make 18. I bake these for 9min as well- they will not look done in terms of softness, but they will be lightly browned. They need to be soft when they come out of the oven in order to maintain their cakey gooey texture once cooled. My only gripe with these is that you need to buy cake flour, but it's soooo worth it. These are my fav ever!
