Old- Fashioned Oatmeal Cake

November 5, 2021 by brooke 3 Comments

Jump to Recipe

This old-fashioned oatmeal cake is a buttery cake loaded with oats and cinnamon and topped with a brown sugar and coconut topping, that gives it some extra texture and sweetness. It's warm and comforting like an oatmeal cookie, and pairs so perfectly with a scoop of vanilla ice cream or a dollop of whip cream.

OLD-FASHIONED OATMEAL CAKE

My Mom always made this cake in the fall, and I would look forward to it year after year. I tend to love anything with cinnamon and oats because it gives it such a wonderful flavor and texture, but eating it warm with a scoop of ice cream makes even better.

It's the perfect cake to serve on a cold night when you want to sit and enjoy a little something sweet while watching a movie or having the fire going.

WHAT IF I DON'T LIKE COCONUT?

If you don't love coconut you could easily frost this cake with any kind of frosting you prefer. Cream cheese would be fabulous!

CAN I ADD CHOCOLATE CHIPS?

YES! ½ cup of chocolate chips would be a great addition to the inside or on top of this cake.

CAN THIS CAKE BE DOUBLED TO SERVE FOR PEOPLE?

You can double this recipe and bake in a 9x13 baking pan instead. I would just set the timer for 30 minutes instead and watch it.

You could also double the recipe and still bake in a 8x8 baking pan for a taller slice of cake.

Notes

The butter and eggs should be room temperature. I try to let them sit out for about 30 minutes before I begin
½ cup of chocolate chips would be a great addition to this cake.
I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
