Heat oven to 350 degrees. In a large bowl, combine the cake mix, cracker crumbs, nuts and butter and mix at a low speed until crumbly. Blend in egg. Press mixture onto an ungreased 12 or 14 inch pizza pan. Bake at 350 for 12-15 or until golden brown. Cool. While cooling, make the filling.

Filling:

In a small bowl, beat cream cheese until fluffy. Gradually add sugar. Blend well. Beat in whipping cream until soft peaks form. Spread cream mixture on cooled crust. Arrange fruit as desired on top.

Keep chilled until ready to serve.
