Note

Why is this recipe interesting?

Sometimes the simplest recipes are the most fun, and this cake is a great example. You only need four basic ingredients, there is no added sugar, and the entire batter can be made in a blender. The apples provide natural sweetness and moisture, so there is no need for extra sugar or oil.

The oats give the cake a hearty texture and provide fiber, while the eggs add protein and help hold everything together. It is a great recipe to keep in mind when you have a few apples that need to be used.

You can also easily change the flavor by adding cinnamon, vanilla, a pinch of salt, or a handful of chopped nuts. Serve it slightly warm, at room temperature, or chilled — it works beautifully as a simple breakfast, snack, or homemade dessert.

  • Use sweet, ripe apples for a naturally sweeter cake.
  • If your apples are very large or juicy, the texture may be slightly softer.
  • Let the cake cool for a few minutes before slicing so it sets properly.
  • Add cinnamon or chopped walnuts for a cozy apple-cake flavor.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
