In a separate bowl, combine the flour, sugar, cinnamon, baking powder, baking soda and salt; add to egg mixture. Add in baby food; mix well.
Transfer to a greased 18x13” half baking sheet. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack.
While the cake cools, make the frosting. In a large bowl, beat cream cheese and butter until light and fluffy (I love using an electric hand mixer, but you can also do it by hand).
Mix in milk and vanilla. Gradually beat in powdered sugar until it reaches the desired consistency (I like to make mine light and fluffy so that it's easier to spread).
Gently spread the frosting on the cake using a spatula.
Cut into squares and serve.
Notes
Don’t be scared by the baby food – it acts kind of like applesauce does in other baked goods, keeping this cake very soft and moist with amazing flavor.
