In a separate large bowl, add in the eggs, both sugars, orange zest, salt, vanilla, and cardamom. Whip on high for 3 minutes until light and fluffy.
Add in the applesauce and oil and mix again.
In a separate bowl whisk together both flours, baking soda and baking powder.
Pour the flour mixture over the grated apple and carrots. Pour in the toasted pecans and dried cranberries (or whichever dried fruit you choose to add).
Fold the grated produce in with the flour mixture and nuts until completely coated.
Dump the produce and flour mixture into the bowl with the whipped eggs and sugar and fold to combine. Be careful to fold and not to stir as you will make the cake tough.
If not using a non-stick USA pan, be sure to line your pan with butter and parchment or a baking spray that includes flour.
Pour the cake batter into a 9" springform pan with tall sides or two separate 9" metal cake pans.
Sprinkle the top of the cake (or one of the cakes) with 50 grams of white granulated sugar.
Bake the cake in the preheated oven for 30 minutes. After 30 minutes, rotate the cake 180 degrees and bake for another 25 to 30 minutes until the top is golden brown and a toothpick inserted in the center comes out clean.
Once baked, remove the cake from the oven and place on a wire rack to cool for at least 30 minutes.
After 30 minutes, remove the cake(s) from the pan(s) and leave to cool completely before filling or frosting.
