Old Fashioned Oatmeal Cake

Old Fashioned Oatmeal Cake with cream cheese frosting. So simple and so so good!

This Old Fashioned Oatmeal Cake is so super simple! It’s soft, cinnamony and topped with creamy cream cheese frosting.

You know that whole thing about eating cake for breakfast? So now’s the time for that.

This super soft and simple cake is packed with oatmeal which I think makes it healthy…and might I mention it’s topped with cream cheese frosting  so you’ve got oatmeal and cream cheese. Yep, breakfast.

Also, can I just say how hard it is to make brown food look delicious? I took 12 trillion photos of this piece of cake to no avail. I tried red hand towels, I tried all white backgrounds, I tried cake in the pan, cake out of the pan… cake without frosting, cake with frosting. Anyhow, brown food’s not so photogenic.

But with that said, let’s see past it’s blah, boring appearance and get to the heart of the matter. This is a cake that your Gram probably made, which automatically makes it the best, and it’s both dense and soft and kinda like banana bread, but not banana-y. Still with me?

The cooked oatmeal that’s baked in gives it a great texture without really tasting like oatmeal. And I should mention you could TOTALLY use leftover oatmeal. Like if you’re that person who makes a big batch of oatmeal and eats it for breakfast throughout the week, you could use that here…even flavored oatmeal would work, I’m thinking brown sugar cinnamon…oh yeahhh!

So let’s get to it. You can whip this up in minutes and it’s perfect for a weeknight dessert, or a potluck meal. Love homey recipes like this one.

Old Fashioned Oatmeal Cake with cream cheese frosting. So simple and such a great way to use up extra oatmeal!

Just soak a cup of oats in some boiling water…


It will make a scant 2 cups of oatmeal if you’re using leftovers…


The cake batter is really easy and when you add the flour, just add the oatmeal too. The moisture from the oats is what keeps your cake moist!


Let the cake cool in the pan and then frost it with cream cheese frosting!


Like I said, this easy cake is perfect for anytime of day!

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts.

This was a great way to use slow cooker apple raisin oatmeal. Added ground ginger to the cake and like one other reviewer wrote only used 1 cup confectioner sugar. Dusted cinnamon on cake after I put icing on. Then topped with walnut halves. Will make again.


Had leftover 9 hr crockpot steel cut oats with dried fruit so i used it… was absolutely fantastic ??????


To make in a 9×13 pan do i triple recipe? thank you.


I would not make this again. The cake was a weird texture, mine did not turn out quite like the photo. I baked it for 35 minutes and took it out without the benefit of a toothpick test, but the whole cake was firm. The icing recipe is WAY too sweet. I should have payed more attention, but the recipe should have called for only one cup of powdered sugar, not two. I have a cream cheese frosting recipe that I always use and it is identical except for just one cup of sugar and a tsp of vanilla. If… Read more »

Kearin @ the winsome baker

I’m on board with anything that has oats in it – one of my absolute favourite things!


I made this for work today and it was very good! Many compliments and there is none left! I did add an extra egg yolk since I like a really dense cake but fabulous recipe! 🙂


I think this cake looks fantastic! I’ve been really into a slice of cake at 4pm lately, and I think this will be the next one on my list–thanks! 🙂


The biggest problem with this blog is that it is virtually impossible to get any actual comments on the recipes. I’m curious, does anyone on this blog ever actually bake any of these cakes or recipes? I mean you all spend your valuable time oohing and ahhing at the pictures…but do any of you actually make the cake and try it? Here’s my suggestion, get off the computer or your couch, roll up your sleeves, stop the inane comments and actually bake a cake or two. These are some really great recipes, but you could spend a lifetime sifting through… Read more »

I baked it tonight! I doubled the recipe and it is delicious.


I agree. Only comment if you have made the recipe. It’s not a fan club.

Anything with oatmeal should count as breakfast 🙂

I’ve always loved old fashioned oatmeal cake. No matter how many time my ex told me to try a newer recipe I said “No”. My love with him may end but with this cake is everlasting, you can tell.


Cant wait to try this later tonight, if you use the quick 1-Minute oats still use one cup and should we still soak for 20 minutes? thank you.

Cake for breakfast? Count me in. This reminds me of a cake my grandma used to make with raisins. Yum!

Jocelyn @BruCrew Life

I am totally on board with cake for breakfast…I just see oatmeal right there 🙂 And your pics look awesome…they have me craving some yummy cake like now!!!

Rachel Parys

I love all things OATMEAL!!! Can’t wait to try this!
Question- do you think it matters if I used quick oats to make the oatmeal with?


Do you think it would make a difference of i substituted margarine for the butter?

Hi. Quick oats or old fashioned? Thanks.


Silly question… if I wanted to take this to a potluck – which I do – can I double the recipe and use a 9×13 pan? Not too good at these conversions. Or double and bake in a bundt pan? Hmmm… What do you advise?

Jenny Flake

Oh this looks so good girl! Need a square this afternoon 🙂


This sounds so yummy. Where did you find your cute pan?


This looks so good. I’m going to try to make these into muffins to make them more portable for the kids lunches. Maybe stuff the centre with some of that delicious cream cheese goodness? Yeah, that’s what I’m gonna do 🙂 Thanks for the recipe!


This looks so delicious. Gonna try to make it this week 🙂


mmmmm….how ’bout adding chopped apple and walnuts or rhubarb!!!
