Prep a deep dish springform pan or a deep dish pie pan by greasing it. Put aside for later use.
Whisk the cream cheese for 5 minutes using the lowest setting. Stir in the vanilla flavoring and stevia as well. Lightly beat the mix. Crack one egg into the mixture then mix again lightly. Continue cracking one egg at a time until all the eggs are used. Finally, mix in the sour cream and stir well.
Spread the mix evenly in the prepared the pan.
Set your oven to 325°F. Take the pan to the oven and leave for 55 minutes. Inspect the cake after 45 minutes. When it turns brown, turn off your oven.
After the time is up, open the oven door and turn the oven off but do not remove the pan. Leave it in the oven for an additional hour.
Take out the pan and let stand to cool thoroughly. Place in the fridge for 12-24 hours to set. Longer hours in the fridge means firmer outcome.
Slice into wedges and serve.
