Preheat the oven to 350℉ (175°C). Place an oven rack in the middle position.
Line a 9 x 9-inch square pan with parchment paper, leaving some overhang for easy lifting. Lightly grease the paper and the pan.
Nut Topping:
Prepare the nut topping by combining almonds, brown sugar and cinnamon.
Reserve about 3 tablespoons of this mixture to spread on top of the cake. Set aside.
The Cake:
In a separate mixing bowl, sift together flour, baking powder, and salt. Set aside.
In another bowl, whisk the eggs together until light and frothy.
Add the sugar and continue to whisk until thick. Whisk for about 2 minutes.
Add the vegetable oil, applesauce and vanilla extract and whisk together for about a minute or so. Set aside while we chop up the apples.
Combine the diced apples to the nut mixture and set aside.
Add dry ingredients to the wet ingredients and combine with a wooden spoon. Do not over mix.
Gently combine the apple mixture.
Pour batter into greased 9 x 9 pan.
Place thinly sliced apples firmly on the top.
Sprinkle reserved 3 tablespoons of nut topping.
Bake in the preheated oven for 50-60 minutes until golden and the cake tester comes out clean.
Allow the cake to cool in the pan for about 15 minutes before using the parchment paper overhang to lift it out. Transfer to a wire rack to cool completely.

Notes
Sifting the dry ingredients together will allow for better distribution of all the ingredients throughout the dry mixture.
When combining the wet and dry ingredients, mix just until combined. Overmixing can lead to a dense cake.
Ovens can vary, so start checking the cake for doneness a few minutes before the suggested baking time. A toothpick inserted into the center should come out clean or with a few moist crumbs.
Allow the cake to cool in the pan for about 15 minutes before lifting it out. This helps it set and makes it easier to handle.
If you want to switch things up, try using walnuts or pecans instead of almonds for a different nutty flavor. They can also be omitted if there are nut allergies in your home.
Serve this apple cake warm or at room temperature. Great at any time of the day.
