Make Fruit Dip Mix according to directions and chill thoroughly.
Bake a brownie mix (without nuts) according to the recipe on the box. You will need to bake it in either a round pizza pan or a jelly roll pan for 10 minutes less than what is on the directions due to the pans being so thin.
Completely cool the brownie crust and spread with chilled Fruit Dip Mix.
Top with sliced bananas, chunk pineapple, and sliced strawberries. (You will need to treat the bananas with Fruit Fresh® or put 3 Tbls. of lemon juice in 1 cup of water and soak the bananas in this for 5 minutes, then drain onto paper towel.)
Drizzle with chocolate syrup and sprinkle with either walnuts or pecans.
