Preheat oven to 350 degrees F. Spray the bottom of a 9 X 13 baking pan with Pam or grease with a bit of butter.

In a medium bowl, combine cake mix, melted butter, and egg. When it is well incorporated, press evenly into a 9 X 13 baking pan. Set aside. Hint: I used the bottom of a mixing cup to get a nice evenly pressed crust.

In a medium bowl, empty the entire jar of Wild Maine Blueberry Jam. Stir with a spoon a bit to help it spread easily over the crust layer.

Pour over the crust and spread evenly. Hint: if just making the gooey butter cake mix bars, omit the fruit layer.

In a large bowl, beat the softened cream cheese and eggs until smooth. This takes a minute or two. Add the powdered sugar and beat another minute or two until it is combined.

Pour over the fruit layer on the crust and spread evenly.

Bake at 350 degrees F. for approximately 45 minutes. Do Not Over Bake. The center will appear soft when done. It will continue to set when cooling. Note: since I used a fruit filling, I baked this for 45 minutes. If I did not have this layer, I would have probably removed this at 35-40 minutes.

When done, remove from the oven and let cook prior to cutting into bars. Enjoy!
