This oatmeal cake recipe is a classic and makes for a nice sweet breakfast/brunch dish. You could also use it as an after dinner dessert, so we’ve included it in both categories for cakes and for breakfast/brunch.

I first discovered this recipe in the vintage Ohio Art Floral Box. The recipe was written a sheet of notepad paper in blue ink and folded a few times. The paper is pretty well-worn, with cooking splatters, so it’s definitely a sign this one was made more than a few times!

The recipe was a little tricky to read because the ink had faded and the paper was dark, but after we scanned it and adjusted the levels in Photoshop it was easier to see the writing.

Here is the original handwritten recipe for Oatmeal Cake:

The front of the piece of paper:

You have to appreciate the folded and crinkled paper – this is exactly how we like to find our vintage recipes!

Here is the back side of the paper, which includes the topping/icing directions:

The “icing” is not so much an icing as it is a broiled topping.

This recipe sounds amazing. Oats, coconut, brown sugar, butter, chopped nuts – I would eat this for breakfast!

I mean, coconut, oats and nuts are generally considered a health food, right?

I have never heard of oatmeal cake or tried it before now, but this sounds like another great recipe to use oats!

Cooking with oats has a lot of advantages – they ARE healthy – and they are relatively inexpensive.

Here are some other recipes on our website that include oats:

How to Make Oatmeal Cake

Making oatmeal cake is pretty simple, you mix the ingredients together, you bake it, you add the topping and then return it back to the oven to broil the topping until toasted.

There are also a lot of variations you could make with this recipe and could use different add-ins if you didn’t want to use nuts. Here’s some ideas to try:

  • Diced Apples
  • Raisins
  • Walnuts
  • Almonds

This seems like a super simple recipe, and of course you could make it the night ahead for breakfast, or make it early in the day if you plan on serving it as a dessert.
