This Oatmeal Cake is a perfect dessert for any time of year. Moist and delicious, topped with coconut and a pecan streusel!
I love oatmeal so much. In all forms. Steel cut, old fashioned, quick…steamed, baked, in cookies, and in cake! Oatmeal Cake, you guys.

This cake ain’t winning any beauty awards, but what it lacks in appearance it makes up for in taste. It’s so good. Anything with a streusel topping, right? The oatmeal even makes it a great excuse to serve it for breakfast. Bet your family won’t object to that!

For the Cake

- 1/2 cup unsalted butter
- 1 cup brown sugar

Instructions
- Preheat the oven to 350°F. Coat a 9×13-inch baking dish with nonstick cooking spray.

Other Notes
This recipe was absolutely delicious. Made it for a friend’s birthday, and everyone not only wanted the recipe, but made it! Making it again this week for a belated valentine party with 11 of my friends! A total winner!!!!!
Topping was a little too sweet. The cake was moist and perfect.
I make this a lot in the fall. My family loves it. I put it under the broiler for a few minutes but watch it close. The coconut burns easy.
Great flavour and delicious cake and great
Delicious
Can the frosting be broiled? Like the broiled coconut ftosting in German Chocolatr cake! Sounds wonderful doesn’t it?
You can try it – just watch it carefully, so it doesn’t burn.
Could you add bananas to this cake?
You could try it. Mashed bananas will add more moisture, though, so you might need to cook it a bit longer. Keep an eye on it.
Can you add the nuts and coconut inside the batter?
Can’t see why not. Try it!
This cake looks so delicious. I love reading the comments and seeing how people have been making this cake for years. Look like I’m going to need to get on board! I can’t wait. Thanks so much for sharing this recipe!
I made this today using quick cooking oats. It turned out great! Very fluffy and moist! I didn’t have pecans so I used some crushed walnuts with the coconut. Great recipe! Thank you.
Has anyone ever used condensed milk?
I have made this since the 60s . It’s the best cake ever.
It was so good I love oatmeal so it is nice to know how many ways to use oatmeal. Thank you
What a wonderful recipe. Thanks for sharing. I used coconut milk rather than the milk. I added apples, walnuts, and dried cranberries to cake batter! Outstanding!
Do you have a recipe for oatmeal pie
This recipe has been a favorite for over 40 years. It certainly will never win The Most Beautiful Dessert award but cannot tell you the number of times guests have been pleasantly surprised at how delicious this nondescript looking cake is….and they usually end up asking for the recipe.
I changed out coconut for apples and dried cranberries! Delish both ways!!!!
Can you use whole milk?
Sure!
Can I use the quick oats which I have on hand? I don’t want to buy the old fashioned oats just for this recipe.
It won’t effect the flavor, but it’s not ideal for texture. Try it!
Can we use quick oats for this recipe?
What can I substitute for the 1 cup of coconut…I cant eat coconut..the rest sounds delicious
Thank you so much for any suggestions
Hi Desi – there isn’t a comparable substitution for coconut, sorry! :(
Does topping need to be pour on the cool cake or can it be done with cake out of oven?
It needs to be spread on top of the cake after it comes out of the oven, as per instructions. Thanks!
I don’t think this answers the OP’s question. Does the cake need to be cool or warm when you top it? I assume warm?
Yep, warm! When it comes out of the oven=warm. It’ll be thick and sets up fairly quickly.
I NEED this cake in my life. And, because it’s full of oats, it MUST be healthy, right? Right!
From what I can see, those of us who don’t have this cake in front of us RIGHT NOW are severely missing out. WANNNNT.
Very nice of you to fill in, so she could take a BREAK. I have a fab oatmeal cake recipe that I got from a friend in high school. Let me tell you the world was flat then. But yours looks soooooooooo similar. So I am going to head over there and take a look.
Thank you again Amy for filling in for me today! This cake looks amazing!
