-I prefer using 2 cups of All Purpose flour and 1 cup of bread flour-The original recipe calls for mixing the chocolate in by hand so the chocolate pieces will not be broken up, I like the breaking up of the chocolate in the cookies a bit, so I simply mix the chocolate in with the flour mixture using the stand mixer set on low. -Trader Joe's Pound Plus Chocolate works well in this recipe and is affordable for most cooks. It is sold in large 1 lb 1.6 oz bars. I use one bar for this recipe, no need to add any additional chocolate. -If you want to produce large flat cookies, bake the cookies immediately after mixing the dough.-This recipe will yield approximately 18-19 large cookies (1/4 cup size scoop) You may also use a smaller scoop, which will yield about 3 dozen 3 inch cookies.
