5 STAR REVIEW

My family loves oatmeal so much. In all forms. Steel cut, old fashioned, quickโ€ฆsteamed, 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 wonโ€™t object to that!

Helpful Tips & Recipe Variations

  • Use old fashioned oats. You’ll need old fashioned rolled oats for this cake. Avoid quick cooking and steel cut.
  • Use whole milk for best results. However, 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 a ยผ cup raisins to the batter if desired.
  • Sprinkle evenly with the granulated sugar for an extra touch. 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 it set, slice, and serve.

    THIS WAS DELICIOUS AND MOIST! BROUGHT AND LEFT SOME AT MY DAUGHTER’S HOUSE AND SHE TEXTED ME FOR THE RECIPE!

  2. Amy Johnson says:

    Hi can you swap out ingredients like to almond milk, almond flour or coconut milk etc? I am picking my battles here.

    1. Amy@BellyFull says:

      I can’t vouch for results without further testing, sorry!

    I’d never heard of oatmeal cake before but decided to try this. My husband took one bite and said Keep this recipe! Absolutely delicious!

  4. Evelyn says:

    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. ?

  6. A E Tansel says:

    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?

    1. Amy@Bellyfull says:

      All these questions are answered in the article and recipe notes of the printable card. Thanks!

      This brought back memories of the McGregor cake popular in the 50s and 60s. I had lost the recipe from my mom in a flood and this cake is just as delicious!

  7. sumiyah says:

    plz guide me how can I induce chocolate chips in it coz me and my kids are chocolate lovers ?

  8. Sue says:

    Could you add fresh cranberries and orange zest to the cake?

  9. Julie says:

    Can i substitute reg salt for the kosher salt, and if so equal amount??

    1. Amy@BellyFull says:

      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.

  11. K says:

    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

  12. Tricia says:

    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.

  13. Jennifer says:

    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?

  14. Tom H says:

    Can this cake be made into layers? And perhaps frosted with buttercream and use the listed frosting as a filling instead?

    1. Amy@BellyFull says:

      You mean once it’s baked? I’m sure you could. Try it!

  15. Joanne says:

    Can I use salted butter

    1. Debbie rara says:

      Could u make a bundt cake instead of a 9X13?

  16. Virginia says:

    Really good with some crushed pineapple and juice

  17. Mary says:

    Do you put frosting on warm cake

  18. Terri Sarazin says:

    Can I use The faster cooking oats? I have 2 canisters of those. Not instant though.

  19. Shirley says:

    Can steel cut oats be used instead of old fashioned ?

    1. Amy@BellyFull says:

      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.

  20. analea says:

    How hot does the milk need to be? I don’t see anything in the recipe about it.

    1. Amy@BellyFull says:

      Hot, like steaming. Enough that the oats can soften as they soak.

      1. Diane says:

        5 stars
        Iโ€™ve made this a few times, itโ€™s soooo good.
        Iโ€™ve added chocolate chips, gives it some extra flavor.

  21. Judy says:

    Is there a specific reason why it calls for skim milk instead of like whole? I usually have whole milk around not skim. Iโ€™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.

  22. Rym says:

    I enjoyed the cake but I cut the sugar in half and the result was perfect

    1. Julia says:

      Thankful that you shared this! Iโ€™m going to try it your way!

  23. Kay Morris says:

    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!

    1. Amy @Belly Full says:

      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.

  24. Charlene Torrence says:

    What can I replace the wheat flour with to make this Gluten free?

    1. Amy @Belly Full says:

      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 friendโ€™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!!!!!

    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

  29. Colleen says:

    Can the frosting be broiled? Like the broiled coconut ftosting in German Chocolatr cake! Sounds wonderful doesnโ€™t it?

    1. Amy @Belly Full says:

      You can try it – just watch it carefully, so it doesn’t burn.

    2. Barbara says:

      We always broiled the frosting on oatmeal cake.

    3. Britt says:

      5 stars
      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.

  30. Cathy says:

    Could you add bananas to this cake?

    1. Amy @Belly Full says:

      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.

    2. Angelia says:

      Can you add the nuts and coconut inside the batter?

      1. Amy @Belly Full says:

        Can’t see why not. Try it!

  31. Chelsea says:

      I made this today using quick cooking oats. It turned out great! Very fluffy and moist! I didnโ€™t have pecans so I used some crushed walnuts with the coconut. Great recipe! Thank you.

  32. Deb says:

    Has anyone ever used condensed milk?

  35. Ali says:

    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!

    1. Deb Bensman says:

      Do you have a recipe for oatmeal pie

  36. Barb says:

    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.

    1. Cathy says:

      Just curious if anyone might have an idea of a broiled topping without the coconut. Donโ€™t understand this but my husband doesnโ€™t like coconut lol ?

  37. Rebecca says:

    I changed out coconut for apples and dried cranberries! Delish both ways!!!!

  38. Gwen says:

    DELISH!

  39. Diane Sherman says:

    Can I use the quick oats which I have on hand? I donโ€™t want to buy the old fashioned oats just for this recipe.

    1. Amy @Belly Full says:

      It won’t effect the flavor, but it’s not ideal for texture. Try it!

    2. Melissa says:

      Can we use quick oats for this recipe?

  40. Desi says:

    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

    1. Amy @Belly Full says:

      Hi Desi – there isn’t a comparable substitution for coconut, sorry! :(

    2. jim says:

      5 stars
      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.

  41. Linda justice says:

    Does topping need to be pour on the cool cake or can it be done with cake out of oven?

    1. Amy @Belly Full says:

      It needs to be spread on top of the cake after it comes out of the oven, as per instructions. Thanks!

      1. Amanda says:

        I donโ€™t think this answers the OPโ€™s question. Does the cake need to be cool or warm when you top it? I assume warm?

        1. Amy @Belly Full says:

          Yep, warm! When it comes out of the oven=warm. It’ll be thick and sets up fairly quickly.

  42. Stephanie says:

    I NEED this cake in my life. And, because it’s full of oats, it MUST be healthy, right? Right!

  43. Joanne says:

    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.

  44. Carol at Wild Goose Mama says:

    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.

  45. Erin @ Dinners, Dishes, and Desserts says:

    Thank you again Amy for filling in for me today! This cake looks amazing!
