Preheat your oven to 180°C (350°F) and grease the 9-inch round cake pan.
In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-5 minutes.
Add the eggs one at a time, mixing well after each addition.
Stir in the grated apples and milk, combining thoroughly.
In another bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to over-mix!
Fold in the chocolate chips gently until evenly distributed.
Pour the batter into the prepared cake pan and spread evenly.
Bake in the preheated oven for 35-40 minutes or until a toothpick inserted into the center comes out clean.
Let the cake rest in the pan for about 10 minutes before transferring to a wire rack to cool completely.
Once cool, garnish with powdered sugar if desired, slice and serve.
