I was introduced to this wonderful Pineapple Oat Cake recipe through my neighbor. Pati loves to bake almost as much as I do. She’s an expert cake decorator, which I certainly can’t claim to be and she is one of the most generous people I know.

When the kids on our street were younger, Pati would offer cookie and cake decorating “classes” to the children that were interested. The kids all loved visiting with Pati, learning how to decorate cookies and of course, eating and bringing home the leftovers.

A few weeks ago, Pati called me to ask if I would like a part of her collection of old cookbooks because she was trimming down her stash. Needless to say, I jumped at the offer.

I especially love vintage cookbooks where the recipe and the instructions aren’t as well written as they are today.

Those are the recipes that make you think and interpret as you go. While some of the recipes in very old cookbooks may not be great ones, there are a few tucked inside that are real gems.

One of the cookbooks my neighbor brought over was a Cooking Light Cookbook from 1992. While I certainly don’t consider this one to be vintage, it’s pretty old as cookbooks go.

As I was going through the pages, I found a recipe for an oat cake that caught my eye.

Oatmeal makes cakes so very moist and adds a great texture. I thought a Pineapple Oat Cake recipe would be a great one to try.

The oat cake ingredient list is simple and the method easy and I loved that this cake baked in an 8 x 8 pan which meant I wouldn’t have much leftover.

How To Make A Pineapple Oat Cake

The pineapple juice is first heated on the stove in a small saucepan, then the oats are added to the warm juice. While the oats stand for about 20 minutes, blend together the other ingredients.

The recipe calls for orange extract but if you don’t have any, lemon extract or vanilla extract will work just fine.

This oatmeal cake is a light cake and could really be called a breakfast cake.

The Pineapple Oat Cake frosting is a simple blend of cream cheese and crushed pineapples.

I wanted the topping to be a little sweeter so I added just a little powdered sugar.

The oatcake will keep well in the refrigerator for 2 days.

Quick and easy to make, this “old” recipe is certainly a keeper. I looked online for the Pineapple Oat Cake recipe so I could link to it for you, but couldn’t find one. I’ve provided the recipe with just a few of my adjustments below.
