Preheat the oven to 350℉/180℃. Grate half of the carrots on the fine side of the grater, and the other on the coarse side (for optimal texture*). Then grate the apples coarsely. Set both aside.
1/2 cup apples*, 1 cup shredded carrots
In a bowl, add the flour, oats, baking soda, baking powder, cornstarch, cinnamon, nutmeg, cloves, and salt. Stir to combine and set aside.
1 3/4 cups all-purpose flour, 1/3 cups rolled oats, 3/4 tsp baking soda, 3/4 tsp baking powder, 1/4 tsp salt, 1 tsp cornstarch, 1 1/2 tsp cinnamon, 1/8 tsp cloves, 1/8 tsp nutmeg
In another large bowl, add the brown sugar, oil, eggs, vanilla, orange zest, and sour cream. Whisk until well combined.
3/4 cups dark brown sugar, 1/2 cup oil, 1/2 cup sour cream, 1 tbsp vanilla, 1 tsp orange zest, 2 large eggs
Add the grated apples and carrots in. Whisk together. Then mix in the dried cranberries, shredded coconut, and chopped pecans in.
1/2 cup apples*, 1/3 cup pecans, 1/3 cup unsweetened shredded coconut, 1/3 cup dried cranberries, 1 cup shredded carrots
Combine the dry and wet ingredients together gently with a spatula, just until a soft muffin batter forms and no flour streaks appear. Do not over-mix!
Transfer into the prepared pan and spread evenly. Add extra dried cranberries and nuts on top if desired.
Bake for 35-50 minutes, depending on your oven. I would start checking at 35 minutes. The cake is ready when a toothpick inserted in the middle of the cake that comes out dry. Allow to cool, slice, and enjoy!
