This is called “Our Favorite” cake for a reason. Super-moist, cinnamon-scented oatmeal cake is topped with a sweet brown sugar and coconut topping, broiled in the oven to give an addictive crunch.
Preheat oven to 325°F (160°C). Lightly grease a 9" x 13” baking pan.
In a large bowl, cream 1/2 cup butter, brown and white sugar. Beat in vanilla and eggs until light and fluffy.
