This easy oatmeal cake recipe is moist, hearty, and uses basic ingredients found right in your pantry. The perfect cake for an afternoon snack!
I love recipes that don’t need any planning. Nothing needs added to the grocery list, and you don’t have to think ahead. This oatmeal cake recipe is exactly that. I’m willing to bet that you have all the ingredients needed to make it, right now, in your pantry. This cake is incredibly moist, because the oats are soaked before being added to the cake batter. It’s an easy step that takes just a minute, but makes a big difference.
Why You’ll Love This Recipe
This oatmeal cake recipe was on an old card in my recipe box, in my mother’s handwriting. It calls for a brown sugar frosting, which I opted to leave off, but included in the recipe variation section. The powdered sugar dusting makes the cake look pretty, and adds just the right finishing touch. There’s something about this recipe that reminds me of when I was a young girl…it’s homey and hearty, simple to make, and delicious.
How To Make Oatmeal Cake
- Preheat oven to 350 degrees F.
- Place the oatmeal in a medium bowl and add the boiling water.
- Stir and let cool.
- In a large bowl, or bowl of a stand mixer, combine the brown sugar, butter, eggs, and one teaspoon vanilla. Mix until well combined and fluffy.
- Add all purpose flour, baking powder, baking soda, cinnamon, and salt.
- Mix well, making sure to scrape the bottom and sides of bowl.
- Add oat mixture and mix until combined.
- Pour into 8 x 8 inch prepared baking dish.
- Bake 25 – 30 minutes until knife inserted in the middle comes out clean. Do not overbake.
- Cool. Sprinkle with powdered sugar.
Recipe Variations
- Add 3/4 cup raisins to the oatmeal/water mixture. The raisins will plump up, and add a sweet texture to the cake.
- Add 1 cup finely chopped walnuts to the cake batter at the very end.
- Other add-in ideas: mini chocolate chips, Craisins, chopped dried apricots.
- Instead of dusting the cake with powdered sugar, serve it with a dollop of whipped cream or Cool Whip.
- Here’s the brown sugar topping from my mom’s recipe card in case you want to try it. Mix together the following:
- 1/2 cup brown sugar
- 6 tablespoons butter (very soft)
- 1/4 cup milk
- 1 cup coconut
- At the end of the baking time, remove the cake from the oven. Switch the oven to broil. Spread the topping on the cake, and broil for 2 or 3 minutes, or until the coconut is toasted. Watch very closely!

Delicious and easy! Made this tonight for my husband and son and we all loved it. I didn’t have a full cup of coconut, so I just used what I had (about 1/4 cup) and tried to adjust the other ingredients to try the topping. It was just enough to give it a little extra something on top. Will definitely make it again.
Great cake!
Ann, thanks for another great recipe! Your recipes are always so delicious! My dear Mom’s Oatmeal Cake recipe is much the same and she always made a brown sugar icing which was so sweet. As a little girl, I loved the icing but don’t like it now as it is just too sweet. However, I am going to make your Oatmeal Cake and use the icing sugar.
Ann, the little sieve with the wooden handle that you use for your icing sugar is like the one that I have which was a gift at one of my showers 55 years ago!
Made this the morning and it was a hit!
Love that all your recipes call for simple ingredients, that most of us already have on hand.
Thanks for sharing 😊
This cake tastes like one my mother used it made. It will be delicious for breakfast.
I was delightfully surprised how good this plain and simple cake is, even without the add-ins!
Thank you for sharing this recipe, I made it for my husband’s birthday yesterday and it was a hit since he loves oatmeal cookies.
I added chocolate chips and drizzled it with a little icing.
Thank you 😊
OOH! Instead of raisins, I’m going to throw in some chopped dates!
THanks for sharing the oatmeal cake recipe. I was looking for my old copy. So this came at a good time. I’m making today. I’ll put chopped pecans in
As always thank you for always sharing
I’ve been making this one for a while but I use 1/2 cup canola oil instead of the butter and whole wheat flour. Less guilt! I do use brown sugar and melted butter and unsweetened coconut with sliced hazelnuts in the topping though, and broil it on the hot cake for 4 minutes. Its the favourite cake here.
This is a lovely recipe! I added a half cup of mini chocolate chips. Perfect for a lazy weekend breakfast or after school snack! Thank you for sharing.
I haven’t made your Oatmeal Cake recipe yet, but I know it will be delicious! Good old fashioned recipes have simple ingredients that you most likely already have in your pantry. Oatmeal cookies with raisins are my all time favorite, so this should turn into a new favorite!
My mother had the same sifter!
Ann, thanks so much for sharing this recipe.
That cakes sounds good. I love to make simple cakes. And I love a cake that can get by with just a bit of powdered sugar dusted over top. I’m not much of a frosting/icing kind of girl.
I will surely give this recipe a try out. I’m sure it’s grand with a cup of tea.
