Gluten Free Oatmeal Cake

READY IN: 1hr 10mins




  • Preheat oven to 325°F.
  • Grease a 13 x9 inch baking dish.
  • Put oatmeal in a bowl and add boiling water. Stir to combine and let stand.
  • Combine 1/2 cup butter with sugars in a mixing bowl and beat on high until light and fluffy.
  • Add eggs, oatmeal, gluten free flours, xanthan gum, baking powder, baking soda, salt, cinnamon and vanilla and beat on low, just until thoroughly blended.
  • Pour cake batter in prepared baking dish.
  • Bake for 35 to 40 minutes, or until a toothpick inserted in the middle of the cake comes out clean.
  • While the cake is baking, combine topping mixture in a bowl.
  • As soon as the cake comes out of the oven, spread the topping mixture evenly over the top of the hot cake.
  • Broil the cake, about 6-inches from the broiler, until the frosting is bubbling and golden brown- about 5 minutes. Watch this step carefully- the topping will burn if left under the broiler too long!
  • Cool before serving -- or eat it warm like we like it!
