Mix cream cheese and make sure it's smooth before adding other ingredients or the dip will be lumpy.

Mix with immersion blender:

cream cheese, sour cream, apple pie filling, brown sugar, pumpkin pie spice and blend until smooth.

You could use a blender or food processor to blend this dip smooth as well.

Garnish dip with Graham Cracker Crumbs resembling a real apple pie for fun.
