Ina Garten's Outrageous Brownies

unsalted butter

plus 12 ounces semisweet chocolate chips

unsweetened chocolate

extra-large eggs

instant coffee granules (I don't really measure the coffee. I'm a batter-taster, so I stir in instant coffee until it taste coffee-y enough.)

pure vanilla extract

sugar

all-purpose flour

baking powder

salt

Optional: 3 cups chopped walnuts, 2-3 Symphony bars

Cook's Note: My godmother has me hooked on a toffee variation. To make it, spread half of the batter in the prepared pan, top with whole Symphony bars (2 or 3) and the remaining batter and bake as usual.
