Creamy Grape Salad w/Marshmallows

Five MILLION, sixty THOUSAND websites showed up when I did a Google search for "Grape Salad"-- some are variations of various grape salad recipes, but a lot of them are quite like this one.  Certainly, there is no serious need for me to add yet "another one just like the other one(s)"...

EXCEPT for the fact that... 

I like to make this 

every now and then.  

INGREDIENTS:

• 2 pounds sweet red seedless grapes.
• 2 pounds sweet green seedless grapes.
• 1 of 8 oz. package of cream cheese, softened.
• 1 cup sour cream.
• 1/2 cup granulated sugar.
• 1 teaspoon vanilla.
• 1/2 of 10 oz. package of miniature marshmallows, optional.

----

• 1/2 cup coarsely chopped pecans (can be roasted/toasted, if you prefer), optional.
• Sprinkling of brown sugar, optional.

DIRECTIONS:

• Wash and pat the grape dry (you can use all green, or all red grapes if that's what you have).  Set aside.
• In a medium mixing bowl, beat together the softened cream cheese, sour cream and the sugar until VERY smooth.  
• Add the vanilla and stir well.
• Add miniature marshmallows and stir in, optional.  
• Put into bowl and sprinkle the pecans over the top.  Immediately before serving, you can lightly sprinkle some brown sugar over top.
