Preheat oven to 350 degrees. Mix boxed brownies according to directions on back of box. Make sure to grease or spray muffin tin well! Scoop or pour brownie mixture, about 2 tablespoons, into mini muffin pans.
Bake brownies until done. About 12 to 15 minutes. These bake pretty quickly in a mini muffin tin.
While they are still hot stuff a Rolo into the center of the brownie. Then press in the pretzel slightly so it will stick and sprinkle with chopped pecans.
Garnish with Caramel and Hot Fudge Topping or melted chocolate if desired.
