Roberts Absolute Best Brownies

• 6 tablespoons (3 ounces/85 g) unsalted or salted butter, cut into pieces
• 8 ounces (225 g) bittersweet or semisweet chocolate, chopped
• 3/4 cup (150 g) sugar
• 1 teaspoon vanilla extract
• 2 large eggs, at room temperature
• 1/4 cup (35 g) all-purpose flour
• 1 cup (about 135 g) walnuts, almonds, hazelnuts, or pecans, toasted and coarsely chopped

1. Preheat the oven to 350F (175C).
2. Line the inside of a 9-inch (23-cm) square pan with 2 lengths of foil, positioning the sheets perpendicular to each other and allowing the excess to extend beyond the edges of the pan.
3. Or, use one large sheet of extrawide foil or parchment paper.
4. Lightly grease the foil or parchment with butter or nonstick cooking spray.
5. In a medium saucepan, melt the butter, then add the chocolate and stir over low heat until the chocolate is melted and smooth.
6. Remove from the heat and stir in the sugar and vanilla until combined.
7. Beat in the eggs one at a time.
8. Add the flour and stir energetically for 1 full minute, until the batter loses its graininess, becomes smooth and glossy, and pulls away a bit from the sides of the saucepan.
9. Stir in the chopped nuts.
10. Scrape the batter into the prepared pan and bake until the center feels almost set, about 30 minutes.
11. Dont overbake.
12. Let cool completely in the pan before lifting out the foil or parchment to remove the brownies.
13. These brownies will keep well for up to 4 days and can be frozen for 1 month.
14. This recipe takes well to mix-ins.
15. Ill sometimes add 1/3 cup (45 g) chopped dried cherries or 1/3 cup (45 g) cocoa nibs to the batter.
16. To make MINTY BROWNIES, crush the contents of one 50-g tin of peppermint Altoids in a sturdy plastic bag.
17. Add the crushed mints to the brownies along with the nuts (or omit the nuts).
18. If you like very minty brownies, add 1/2 teaspoon mint extract along with the crushed mints.
19. To cut brownies perfectly, remove them from the pan, peel away the foil or parchment, and set them on a cutting board.
20. Use a long serrated bread knife, dipping the blade in very hot water and wiping it on a paper towel between each slice.
21. Trim off the edges of the brownies with long, slicing strokes, then, use the same motion to cut the brownies into squares or rectangles.
22. For positively picture-perfect brownies with neat, clean edges, freeze the brownies in the pan before cutting.
