This oatmeal cake is a wonderfully moist, fluffy, soft sheet cake, using oats and apple sauce. Tastes like carrot cake! Easy homemade recipe and a family favorite.

This oatmeal cake is great tasting, soft, moist, and incredibly easy to make. The ingredients are made up of regular pantry ingredients, and it's certainly an economical and budget-friendly recipe.
For this recipe, we've made it in a large sheet pan, so it's perfect for a party, to take to a pot luck or if you're baking for a lot of people. It'll make around 12 to 18 slices.
It's a traditional, old fashioned cake recipe. As you'll probably know, many cakes back in the day were made using whatever ingredients were available in the pantry. Particularly when certain staples, such as sugar, butter, and other items were scarce or rationed. Grandma always came up with a good recipe!

The addition of the nutmeg and cinnamon spices lifts the cake to another level, giving it bags of flavor. The aroma when this is baking is out of this world!

This delicious recipe has been generously shared by one of our great cooks, Carina. Carina says this cake is very easy to make, and if you're wondering what it tastes like, well, it's similar to a carrot cake.
It is quite a sweet cake, (Carina's hubby has a very sweet tooth!) and Carina advises that you reduce the sugar in the frosting to your taste, or leave out completely and make a cream cheese frosting if you don't like very sweet cakes. It's up to you!
Needless to say, this cake is a hit with Cari's family and especially hubby, who couldn't wait to have a slice!

ramona endicott

Dee Dee
says:I made this recipe and decreased the sugar by 1/3 in the cake mixer, leaving the icing according to recipe.
After supper I brought my boyfriend a piece and asked him for one word to describe his first impression, his word was squishy and my word was interesting. We both agreed it was good but is different than what you may consider most cake. Will probably make again with some adjustments.
