This old fashioned Oatmeal Cake is a perfect dessert for any time of year. Moist and delicious, topped with coconut and a pecan streusel!
My family loves oatmeal so much. In all forms. Steel cut, old fashioned, quick…steamed, baked oatmeal, in oatmeal raisin cookies and banana oatmeal pancakes, and in this oatmeal cake!
This cake probably isn’t winning any beauty awards, but what it lacks in appearance it makes up for in taste. It’s moist, flavorful, with a crisp streusel topping, and just so good. Anything with a streusel topping, right? The oats even make it a great excuse to serve it for breakfast. Bet your family won’t object to that!

What’s in This Old Fashioned Oatmeal Cake Recipe?
This oatmeal cake calls for standard pantry items. (Scroll below to the printable recipe card for details and measurements.)
- Oats – You’ll need old fashioned rolled oats for this cake. Avoid quick cooking and steel cut.
- Flour – Regular all purpose flour, spooned and leveled to avoid excess and a crumbly cake.
- Sugars – Both granulated and brown sugar for the best sweetness.
- Baking soda – This leavening agent helps make the cake texture light and fluffy.
- Cinnamon, Salt, and vanilla – For warmth and flavor.
- Milk – For best results use whole milk.
- Unsalted butter – If you only have regular salted butter, omit the additional salt.
- Eggs – Provides structure to the batter.
- Coconut Flakes and Chopped Pecans – These are included in the streusel topping and add fantastic flavor and texture.
Recipe Variations
- Change the liquid. Instead of whole milk, you can use reduced fat milk or even water (for less calories, but it won’t be as flavorful), or use cream for more richness.
- Try a different nut. Replace the pecans with walnuts, or just simply omit them.
- Omit the coconut. If coconut is not your thing, you can simply omit it.
- Add some raisins. Add in a 1/4 cup raisins to the batter.
Proper Storage
- On the counter. Store oatmeal cake leftovers, tightly covered, for up to 2 days.
- In the refrigerator. Store tightly covered, for up to 5 days (bring to room temperature before serving.)
- To freeze. Tightly sealed and covered in an airtight container for up to 2 months. Thaw in the refrigerator overnight.

Oatmeal Cake
Ingredients
For the Cake
- 1 & 1/2 cups hot whole milk
- 1 cup old fashioned rolled oats
- 1 & 1/3 cups all-purpose flour , spooned and leveled
- 1 teaspoon cinnamon
- 1 teaspoon baking soda
- 1/2 teaspoon coarse salt
- 1/2 cup unsalted butter , at room temperature
- 1 cup brown sugar
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla
For the Streusel Topping
- 1/2 cup unsalted butter
- 1 cup brown sugar
- 1 tablespoon whole milk
- 1 cup unsweetened coconut flakes
- 1/2 cup finely chopped pecans
- 1/4 cup granulated sugar (optional)
Instructions
- Preheat the oven to 350°F. Coat a 9×13-inch baking dish with nonstick cooking spray.
- In a medium bowl, combine the hot milk and the oats; allow to soak while you prepare the remaining ingredients.
- In another medium bowl, whisk together the flour, cinnamon, baking soda, and salt.
- In a large bowl with an electric mixer, cream together the butter and both sugars. Beat in the eggs and vanilla. Add half of the flour to the creamed butter mixture, followed by the soaked oats (including any liquid), then the remaining flour, mixing between additions.
- Pour into the prepared baking dish and bake until set, 35-40 minutes.
- For the topping, put the butter, brown sugar, and milk in a saucepan. Bring to a boil, while stirring. Once sugar is dissolved, remove from heat. Stir in the coconut and pecans. (Mixture will be thick.) Spread over the cake evenly.
- Let stand for about 10 minutes before cutting and serving.Optional addition: Sprinkle evenly with the granulated sugar. Using a kitchen torch, heat the sugar in a circular motion until caramelized (but not too close or it will burn) or place under the broiler for a minute or two. Let set, slice, and serve.
This was simple and wonderful. My grandmother used to make this and it brought back lovely memories for me. Thank you for sharing.
I really loved this recipe and my husband can’t wait for me to make it again. I did put the cake and topping in the oven for a little bit to crisp up the edges. Served with French vanilla ice cream and caramel sauce. ?
Quick question: For the streusel topping, I’m omitting the coconut flakes because I don’t like the texture, but I love the flavor! Can I replace the milk for coconut milk, that way I still get the flavor without the texture? Oh also, can I use either sliced or slivered almonds?
All these questions are answered in the article and recipe notes of the printable card. Thanks!
plz guide me how can I induce chocolate chips in it coz me and my kids are chocolate lovers ?
Could you add fresh cranberries and orange zest to the cake?
Can i substitute reg salt for the kosher salt, and if so equal amount??
Table salt is much finer and stronger, so you’ll want to cut the amount in half.
I was making this cake over 40 years ago. Somehow i lost the recipe. Now i can make it again. One of my favorite cakes.
Have made this for years. Everyone loves it. Very moist and always comes out perfectly. Can serve it cold, but warm feels like a big hug
My grandma made a cake similar to this one, and after she put the topping on, she would put it under the broiler in the oven for a bit. Keep an eye on it so it doesn’t burn. It caramelizes it all together.
Have you tried this with a nut or rice flour? If so, how did it turn out? Did you have to alter any of the other ingredients?
Can this cake be made into layers? And perhaps frosted with buttercream and use the listed frosting as a filling instead?
You mean once it’s baked? I’m sure you could. Try it!
Can I use salted butter
Could u make a bundt cake instead of a 9X13?
Really good with some crushed pineapple and juice
Do you put frosting on warm cake
Can I use The faster cooking oats? I have 2 canisters of those. Not instant though.
Can steel cut oats be used instead of old fashioned ?
I haven’t tried this recipe with steel cut oats. The problem is that they won’t soften up enough in the hot milk like rolled oats do. And they also might lend too much of a grainy texture.
How hot does the milk need to be? I don’t see anything in the recipe about it.
Hot, like steaming. Enough that the oats can soften as they soak.
I’ve made this a few times, it’s soooo good.
I’ve added chocolate chips, gives it some extra flavor.
Is there a specific reason why it calls for skim milk instead of like whole? I usually have whole milk around not skim. I’m assuming it is to cut back on the fat in it. Also, I only have the quick oats, not instant, to use you said, that affect the texture.
I enjoyed the cake but I cut the sugar in half and the result was perfect
Thankful that you shared this! I’m going to try it your way!
This looks delish! Do you think it could be made into cupcakes? When I visit my grandson at college, I always like to take hime something homemade and cupcakes are easiers for him to share with his frat brothers. Thanks!
Hi Kay! I can’t see a reason why it wouldn’t work. You’ll just need to bake them for a lot less time. Most cupcakes bake for 18-25 minutes, so fill them three-quarters of the way full in cupcake liners and start testing at 18 minutes and go from there until they’re done.
What can I replace the wheat flour with to make this Gluten free?
Hi Charlene! This recipe has only been tested as written, so I can’t vouch for flour substitutes.
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 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 so the coconut doesn’t burn.
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.
We always broiled the frosting on oatmeal cake.
Hey Colleen in the cookbook called The Joy of Cooking there is a recipe for oatmeal cake that calls for broiled icing. Hope this helps! It is what led me to this recipe on line then I saw your comment.
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 is so delicious. I love reading the comments and seeing how people have been making this cake for years. 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.
Just curious if anyone might have an idea of a broiled topping without the coconut. Don’t understand this but my husband doesn’t like coconut lol ?
I changed out coconut for apples and dried cranberries! Delish both ways!!!!
DELISH!
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! :(
I’ve always made it with oatmeal (not coconut) in the frosting. Tastes great! You may need to let the oatmeal set in the hot caramel mixture a while to soften it up before you spread it on.
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!
