Old Fashioned Oatmeal Cake is a classic cake recipe tastes like a spiced cake but has a wonderful texture of oatmeal. The boiled frosting is packed full of nuts and coconut. This cake is not to be missed.

This oatmeal cake is a moist cake that stays fresh for several days. So it’s the perfect cake to prepare a day or two you want to serve it.

Origin of Oatmeal Cake is unknown

It’s hard to say if this recipe had its origin from the Scottish oatcake. Or if this cake same from trying to use up leftover oatmeal. No matter where this cake came from, you will find that it is a complex cake that is perfect to stand up to a cup of coffee or to be served as dessert.

For this recipe, I really like to use dark brown sugar in both the cake and then in the boiled frosting. The dark brown sugar gives a rich flavor that light brown sugar does not have. Both dark and light brown sugar will work in this case.

I think the real highlight of this cake this the frosting, this caramel boiled frosting, is rich and full of flavor. The nuts toast just a bit when the frosting cooks. Topping this slightly spiced cake with the complex flavors this topping is a real delight.
