This is wonderful and so easy to make. I wanted to try it out for Christmas and made this and talk about good. I got this recipe from Paula Deen's Christmas magazine. This is not for those watching calories.
Bake brownies according to package. Let cool and crumble brownies, set aside.
In a large saucepan, combine sugar, corn syrup, melted butter and eggs. Stir in salt, vanilla and chopped pecans. Bring to a boil over medium heat; reduce heat and simmer for 10 minutes, stirring frequently. Cool completely.
In a trifle dish layer brownies, pecan mixture, whipped topping, caramel and toasted whole pecans as desired. Chill for two hours before serving.
Can also make mini trifles by using small clear dessert dishes to make individual servings.
