This cake was popular in the late 60's, early 70's but it is my mother's recipe. I don't know how it got the name Doodle cake but it is similar to Hummingbird cake or Dr. Bird cake. This cake was made for many church potluck dinners. This cake is very moist and hard to eat one piece. you can add pecans to the topping but it is fine the way it is. Enjoy!
