Two cups of cocoa powder. Its a lot but it gives it a rich, deep chocolate flavor.
4 teaspoons of vanilla
1 teaspoon salt
2 cups of flour
Add 2 cups of chopped walnuts.
Bake at 350 degrees
And honestly I couldn't tell you how long this bakes. I'd set the timer for 35 minutes and check it. It depends on how hot your oven is but I usually end up baking them for 45 minutes or so. It just depends. But don't rely on the toothpick test because these are supposed to be very gooey. I usually bake them until the edges appear done but the middle looks a bit underbaked.
These are addictive. Just ask my family.
I'd say it probably serves about 15 people,
Or a mom and two teenage daughers.
No, I'm kiddng it usually last our family up to two days. :)
