Step 6

Fold in the shredded apples and walnuts until evenly combined.

Step 7

Pour the batter into the cake pan.

In a small mixing bowl, combine sugar and cinnamon and mix evenly with a spoon. Sprinkle the cinnamon sugar on top of the batter.

Bake the cake on the middle rack for 35-40 minutes until golden brown and a toothpick inserted into the center of the cake comes out clean.

Step 10

Let it cool for 10-15 minutes in the pan, then invert to remove the cake and allow it to cool completely on a wire cooling rack.
