Triple Chocolate Toffee Brownies

2 (1 ounce) squares unsweetened chocolate
1/2 cup unsalted butter
1 1/4 cups granulated sugar
1 teaspoon vanilla extract
2 eggs, lightly beaten
1/2 cup flour
1 tablespoon plus 1 teaspoon cocoa
1/4 teaspoon salt
2 Heath? candy bars, chopped
1/2 cup chopped pecans, toasted

Preheat oven to 350 degrees F. Butter an 8-inch square baking pan.

In a heavy saucepan, melt the unsweetened chocolate with the butter over low heat. Remove the pan from the heat, and stir in the sugar and vanilla extract to cool the chocolate slightly. Add the eggs, beating well by hand. Sprinkle in the flour, cocoa, salt, chopped Heath? bars, and pecans. Stir to combine everything, but do not over-mix. Pour the batter into the prepared pan and bake for 23 to 25 minutes. The brownies should remain a little "smooshy" in the center. Let them cool for at least 15 minutes before cutting and serving.
