Preheat the oven to 350 degrees.

Cover a 9.25 X 5.25 X 2.75 loaf tin in wax paper.

Cut 1 apple into long vertical thin slices and then cut those slices in half horizontally (this is to ensure that the slices aren't so long that they stick out of the batter), then put the slices into a small bowl. Pour 2 tsp maple syrup on top of the apples. Then put 1/2 tsp of cinnamon and 1/8 tsp of nutmeg on top of the sliced apples and mix everything together with a spoon. Set the bowl aside.

In bowl 1, mix the almond flour, coconut flour, baking soda, baking powder, salt, 1/2 tsp cinnamon, and 1/8 tsp nutmeg together with a fork. Set the bowl aside.

In bowl 2, mix the eggs, honey, vanilla, coconut oil, and mashed banana together with an electric mixer until well mixed. Add the apple sauce and mix with the electric mixer until well blended.

Put bowl 1 into bowl 2 and mix with an electric mixer.

Pour the batter into the waxed loaf tin and pat it down evenly with the back of a metal spoon or a spatula.

Then start vertically inserting the slices of apples into the batter in rows. Make sure to insert the apple slices close together but still leaving some batter in between each slice. Also make sure the rows of apples aren't too far apart. Once all the apple slices are upright in the batter, bake for 60 minutes.

Remove from the oven and let cool completely.

Remove the wax paper from the cake and enjoy!
