This Bar has all the flavor that the classic cake has but is made with a secret ingredient.....baby food!
Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x13 inch pan. Mix the flour, baking soda, salt, and cinnamon.
In a large bowl, combine eggs, sugar, and oil. Beat until smooth. Beat in the flour mixture alternately with the baby food. Pour batter into prepared pan.
Bake in the preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center of the cake comes out clean. Completely cool before frosting.
Into another bowl, whisk cream cheese and butter until smooth.
Stir in vanilla, portion by portion, mix in sugar until well blended.
Frost over the cooled pastry and cut into bars.
