Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan or line it with parchment paper.
In a bowl, whisk together the almond flour, oat flour, cinnamon, baking powder, baking soda, and salt.
In a separate bowl, whisk together the eggs, applesauce, melted coconut oil, maple syrup, vanilla extract, and almond milk.
Gradually add the wet ingredients to the dry ingredients, stirring until well combined.
Fold in the chopped apples.
Pour the batter into the prepared cake pan and spread evenly.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool before serving. Enjoy!
