*All my cookie recipes are half-recipes, so they use half an egg. A large egg is 50 grams. So, whisk it well, then measure out 25 grams. Better yet, just double the recipe and use 1 full egg.
I make half recipes at school because students don't need more than 12 cookies. I make half recipes at home because I have no self control.
The baking time on these can be variable, depending on your oven. Also, since the dough is brown, it's harder to tell by eye when they are done. They should be quite firm on the sides, otherwise, the cookies tend to collapse. Yes, you can leave out the raisins, but you're missing out. Trust me.
