These are really good. They are slightly crispy around the edges, and I love how they 'crackle' as you bite into them. Firm in the middle, with great flavour. What I did..... - used a 300 gr bag of chips which is about 1-1/2 cups. - didn't have quite enough brown sugar, used just under the 1-1/2 cups called for, and it was light brown. - used a 1 tbsp scoop for the dough. The first two batches I just dropped on the cookie sheet, the following batches I rolled them in my hand and then pressed down with two fingers. - they measure approx 2-1/2 inches in diameter. I ended up with 5-1/2 dozen cookies. They took 15 minutes in my oven. Thanks Elly for posting.
