Brownie Crackle - cooking recipe

Ingredients

1/4 lb unsalted butter, 1 stick
1 ounce unsweetened chocolate, chopped
1/2 cup granulated sugar
1/4 teaspoon vanilla extract
1 large egg
1/3 cup all-purpose flour
1/2 cup walnuts, crushed

Preparation

Melt butter in a large sauce pan over medium heat. When almost all melted add the chopped (or whole) chocolate and melt completely.
Add the sugar, vanilla and egg, and mix thoroughly until the crystals are incorporated. Now add the flour and nuts and mix well.
Place a silpat baking liner on a one-half sheet pan and pour batter over the silpat(or parchment paper). Spread the batter very thin and evenly. Don't worry about it being pretty, even is what you want.
Bake at 375*F for about 20 minutes watching so it doesn't burn. You want it completely baked and almost completely dry to the touch.
