Fudgy brownies with plenty of caramel and pecans!
Position a rack in the center of the oven and preheat the oven to 350°F. Spray the bottom and sides of a 9x13-inch baking pan with nonstick spray.
Put the butter and chocolate in a medium saucepan over low heat and stir constantly until melted and smooth. Remove from heat and set aside.
In a medium bowl, whisk the eggs until well blended. Gradually whisk in the sugar and then whisk vigorously until well blended. Whisk in the melted chocolate mixture, vanilla extract, and salt. Whisk in the flour and cocoa powder until blended. Stir in the pecans, and then scrape the batter into the prepared pan, smoothing it into an even layer with a spatula.
