Purple Flurp

This recipe is from my Grandma Brown. I grew up eating this at all the summer family get-togethers. I haven't had it for many years because I haven't been home in the summer in a long time. I have been craving it, so I finally called and got the recipe from Gram. It's light and easy and good! PS--I don't know what the recipe's real name is. It's probably something boring like blueberry dream dessert. The story goes my uncle called it Purple Flurp the first time Grandma made it and it stuck.

2 1/2 cups graham cracker crumbs (I buy the crumbs because I like how fine they are)
1 stick butter, melted
6 T sugar
Mix above together and set aside.

1 large box Dream Whip (have 4 envelopes in it)
1 cup milk
Mix these together and add 1 1/2 cups powdered sugar and 1 t vanilla. Then add 1 8 oz cream cheese that has been whipped. Mix til blended well.

1 can blueberry pie filling

Layer in a 9x13 pan in this order: 1/2 the graham cracker crumbs, 1/2 the dream whip mixture, whole can pie filling, remaining dream whip mixture, remaining graham crumbs. Chill and serve.
