Preheat the oven to 375° and lightly grease a 9x13 pan.
Add all the ingredients to a large bowl in the order they are listed. Stir together and beat until the mixture is smooth. Mix in nuts, chips etc. that you’d like to use.
Spoon into the prepared pan and bake 25-30 minutes, or until just barely beginning to pull away from the sides of the pan, remove from oven and let cool.
