1 box Duncan Hines chewy brownie mix
4 tablespoons butter
1 cup chopped pecans
1 cup firmly packed light brown sugar
Heat oven to 350 degrees F.
Prepare the brownie mix according to the package directions. Pour batter into a greased 9 x 13-inch pan.
Melt the butter in a small saucepan. Add the pecans and sugar and cook, over medium heat, stirring frequently, until the sugar dissolves. Drizzle the caramel mixture over brownie batter and bake until a wooden pick can be inserted and withdrawn cleanly, 25 to 30 minutes.
