Oatmeal Cake

Oatmeal Cake is the perfect dessert! It’s an grandma kind of recipe. It’s has oatmeal, cinnamon, and a kiss from grandma!  Since the oats are soaked in boiling water it  gives you a moist and tender cake.


Oatmeal Cake


A couple of weeks ago it was my Mother in law’s birthday. I thought since it was her birthday that we should get her a cake so when people came to visit her she had a delicious treat to serve. We asked her what kind of cake she wanted and this is what she requested! Mind you, I had never heard of a Oatmeal Cake before, and honestly I thought it would be terrible!!


Let me put your mind to ease, it was NOT terrible but the most moist, delicious cake I have tasted in a long time!

There are many reasons that I fell in love with this cake. First, like I said, it reminds me of something my grandma would have made. Second, the flavor is crazy good and so moist! And third It’s such a easy cake to make! 



How to Store 

  • You can store oatmeal cake covered at room temperature for up to 2 to 3 days
  • You cover and chill in the refrigerator for about 5 days, bring to room temperature before serving, but you won’t have to worry about that because it will be gone!
  • Cake can also be frozen for 2 months in an airtight container. Thaw overnight in the refrigerator.

Possible Change Variations

  • If you hate coconut it can be omitted. We didn’t have any and my family doesn’t love it, so we didn’t add it.
  • If you don’t like nuts those can be omitted, if you love them feel free to double them up. Pick your favorite nut! It might change the flavor a little but it will still be amazing!
  • For a more caramel flavor in the cake use all brown sugar and omit the granulated.
  • Add raisins if you like raisins in cake. We didn’t add them but I think they would be amazing in this cake!
  • Use cream or half and half in place of the water for even more richness.
  • Skip the nutmeg if you don’t have it.

  1. This is the perfect cake. I love everything in it. I am definitely going to try this one. I think I have everything in-house already except the walnuts and coconut. Love this recipe. Thanks for sharing at #omhgww. See you next week. Pinned & Tweeted if buttons are available. Happy weekend.

  2. I had to come see the recipes and yes it is just like the one my mother in law use to make 50 years ago, gosh thats a long time ago. then I started making it, it was one of those desserts that used to eat in the middle of the night. She used to make a topping with butter, br sugar, pecans or walnuts and coconut and broil it, the butter would seep down thorough the cake with the brown sugar. Oh my I just might have to try this again. Thank you for sharing on Oh My Heartsie Girls Wonderful Wednesday.

    1. I had never had it before, and I had to try it because of my mother in law. It’s so good!
