Step 1

Salad: Wash the grapes (4 pounds) then lay them out on paper towels, turning over at least once, to dry thoroughly.

Step 2

In a very large mixing bowl, using a handheld electric mixer, combine the cream cheese (8 ounces), sour cream (8 ounces), sugar (1/2 cup), and vanilla (1 cup) until smooth. Add grapes toss well to evenly coat. Cover and refrigerate at least 4 hours.

Step 3

Topping: In a small mixing bowl, combine brown sugar (1 cup) and pecans (1 cup).

Step 4

Spread salad out on a large rimmed serving dish or a 9 X 13-inch baking dish. Sprinkle with topping and serve.
