Preheat oven to 350° F. Grease a 9 x 13 inch baking pan. In a large bowl, whisk together the flour, oats, brown sugar, cinnamon and salt. Pour in the melted butter and stir until crumbly. Firmly press 1/2 of the mixture in the bottom of the prepared baking pan. Set aside.

In another large bowl, beat together the cream cheese and granulated sugar until smooth. A hand mixer makes this easy. Then, add the pumpkin, flour, pumpkin pie spice and cream. Beat again until smooth. Last, add the eggs one at a time, beating just until combined.

Pour the pumpkin mixture over the crust and gently spread around. Finally, crumble on the remaining streusel mixture. Bake at 350° for 35-45 minutes or until the center is set and no longer jiggles. Let cool completely before serving.

Store tightly covered in the refrigerator for up to several days.
