This apple cinnamon oatmeal cake is a hearty and wholesome dessert that's perfect for fall. It's a moist and chewy cake with a crunchy oatmeal topping. To make this cake, you'll need all-purpose flour, baking powder, salt, sugar, eggs, vegetable oil, vanilla extract, apples, cinnamon, rolled oats, and brown sugar. Mix the dry ingredients in one bowl and the wet ingredients in another. Combine the two mixtures and fold in the chopped apples. Pour the batter into a greased baking pan and sprinkle the oatmeal topping on top. To make the topping, mix rolled oats, brown sugar, cinnamon, and butter until crumbly. Bake the cake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool before slicing and serving.
