Preheat the oven to 350ºF and grease a 9x13 inch glass or ceramic baking pan.
In a large bowl, whisk together the pumpkin, eggs, sweetener, whipping cream, pumpkin spice, and salt. Measure out ½ cup of the cake mix and whisk into the pumpkin mixture until smooth.
Pour into the prepared baking pan, then sprinkle the remaining cake mix evenly overtop.
In a small bowl, whisk the pecans with the Swerve Brown. Sprinkle this evenly over the cake mix, then drizzle the melted butter evenly over the pecans.
Bake 45 to 55 minutes, until the top is just firm to the touch and a rich, deep brown. It will still be very soft underneath.
Remove and let cool. You can also eat it warm, or chill it in the refrigerator to firm it up!
