1 pkg. chewy brownie mix (recommended: Duncan Hines)
4 tbsp. butter
1 c. chopped pecans
1 c. firmly packed light brown sugar

Preheat oven to 350°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 Drizzle the caramel mixture over brownie batter and bake until a toothpick can be inserted and withdrawn cleanly, 25 to 30 minutes.
