Step 1: Prepare the Grapes - Begin by washing the grapes thoroughly under cold water. Remove the stems and pat them dry with a clean kitchen towel. Halve the grapes and set them aside in a large mixing bowl.
Step 2: Blend the Creamy Base - In another large mixing bowl, add the room temperature cream cheese. Using an electric mixer, beat the cream cheese until it's smooth and creamy. This will take about 2-3 minutes.
Step 3: Add Sour Cream and Sugar - To the creamy mixture, add the sour cream, sugar, and vanilla extract. Continue beating until all ingredients are well combined and the mixture is fluffy.
Step 4: Fold in Grapes and Pecans - Gently fold the halved grapes and finely chopped pecans into the creamy mixture using a spatula. Be careful not to crush the grapes; you want them to retain their shape.
Step 5: Sweeten it Up - Sprinkle the brown sugar over the top of the salad. Gently mix it in to distribute the sweetness throughout.
Step 6: Chill and Serve - Transfer the salad to your serving dish, cover with plastic wrap, and refrigerate for at least 2 hours before serving. This chill time allows the flavors to meld beautifully.
