Prepare either a 1/2 sheet pan or 9x13 pan with baking spray. Combine the eggs, sugar, oil and baby food.
Fold in the dry ingredients: flour, baking soda, salt and cinnamon. Combine well.
Pour batter in to preferred pan. Bake at 350 degrees for 20 minutes for sheet pan and about 30 minutes for 9x13 pan. Test with toothpick in center for doneness.
Combine frosting ingredients until smooth. Frost on cooled cake. Cut into bars. For the Fall season, I sprinkle Fall colored "jimmies" on top. These are great for Bake Sales, cut and put in packages of six.
