Wash and dry grapes and place in large bowl. Set aside.
In medium bowl, mix together cream cheese, sour cream, sugar, and vanilla, stirring until completely smooth.
Add sweet dressing mixture to grapes. Stir until evenly coated. Cover bowl and place in refrigerator at least 30 minutes, until ready to serve.
Immediately before serving, stir in ¼ cup chopped pecans, mixing until fully incorporated. Top grape salad with remaining ¼ cup pecans and sprinkle on brown sugar to garnish. Serve immediately after garnishing.
Recipe Notes
Cream cheese must be completely softened or the consistency of the sweet dressing mixture will be off.
If your grapes are very tart, you may want to increase the sugar to balance it out. If they're very sweet, reduce the sugar so it's not overwhelming.
Make it Reduced Sugar: Use equal amounts granular Swerve in place of the white sugar and Brown Swerve in place of the brown sugar.
Make it Dairy Free: Use vegan cream cheese, and replace the sour cream with vegan sour cream or dairy-free yogurt.
Make it Vegan: Use vegan cream cheese, and replace the sour cream with vegan sour cream or dairy-free yogurt. Make sure your white sugar is vegan, or use a sugar substitute.
