Triple Chocolate Brownies

• 3 sticks plus 2 T. unsalted butter
• 12 oz. best-quality bittersweet chocolate
• 6 eggs
• 1 3/4 C. superfine sugar
• 1 T. pure vanilla extract
• 1 1/2 C. plus 2 T. all-purpose flour
• 1 tsp. salt
• 1/2 C. white chocolate buttons, chips or morsels
• 1/2 C. semisweet chocolate buttons, chips or morsels
• Approx. 2 tsp. confectioner's sugar, for garnish

1. Preheat oven to 350.
2. Melt the butter and dark chocolate together in a large heavy based pan over a low heat.
3. In a bowl or large measuring jug, beat the eggs together with the superfine sugar and vanilla extract. Beat well for several minutes.
4. Allow the chocolate mixture to cool a little, then add the egg and sugar mixture and beat well. Fold in the flour and salt. Then stir in the white chocolate buttons or chips and the semisweet chocolate buttons or chips. Beat to combine then scrape and pour the brownie mixture into the prepared tin.
5. Bake for about 25 min.~ You can see when the brownies are ready because the top dries to a slightly paler brown speckle, while the middle remains dark, dense and gooey. Even with such a big batch you do need to keep checking on it, the difference between gooey brownies and dry ones is only a few minutes. Remember, too, that they will continue to cook as they cool. (I baked them for 22 min.)
6. Sprinkle with confectioner's sugar, if desired.
