Whisk the egg yolks, then add the applesauce, jam, cinnamon, and cashew butter. Mix everything thoroughly.
Add coconut flour and a pinch of baking soda. After you mix everything together, add the desiccated coconut and mix once again until everything is well incorporated.
Whisk the egg whites with a hand mixer, then add a little bit of the egg white foam to the other mixture and fold together. Then, add this mixture to the rest of the egg whites and fold everything carefully using a wooden or silicone spatula.
Bake for about 18 minutes or until the cake is golden brown and a toothpick comes out clean.
