Butter; to grease the foil
16 T. Unsalted butter; softened
2 C. Sugar
8 oz. Bittersweet chocolate melted and slightly cooled
2 t. Vanilla extract
4 Eggs
1 C. Unbleached all-purpose flour
1 t. Salt
1 C. Chopped walnuts
2 C. Semisweet chocolate
2 C. Milk chocolate
2 C. Butterscotch bits
Preheat oven to 350F. Line an 8 3/4-by-13 1/2-inch glass or metal pan
with a large piece of aluminum foil, smoothing it into the corners. Butter
the foil.
In a large bowl, cream the butter with the sugar together until it is
light in color. Stir in the melted chocolate. Add the vanilla, then add
the eggs, beating until blended. In another bowl, combine the flour and
salt. Add the walnuts and all the bits, tossing to coat them with the
flour. Scrape the flour, nuts and bits into the bowl with the butter,
and stir with a wooden spoon just until all the ingredients are mixed.
Do not over-beat. Scrape the batter into the prepared pan, holding the
foil so that it does not move.
Place the pan in the middle of the oven and bake until a toothpick inserted
in the center comes out almost clean, about 50 minutes. Remove the pan
and let it stand for an hour, then cover the pan with foil and place it
in your freezer for at least 1 1/2 hours or in your refrigerator overnight.
Turn the cooled brownies out onto a clean workspace, lift off the foil
and cut into 32 squares. Store in the refrigerator or the freezer in an
airtight tin.
