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.

Easy Oatmeal Cake 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 chopped walnuts to the cake batter at the very end.
  • Instead of dusting the cake with powdered sugar, serve it with a dollop of whipped cream or Cool Whip.

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 that is cooked on the stove, which I opted to leave off. 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.
