1
Mix all the dry ingredients in a bowl.
2
Mix the wet ingredients + sweetener + vanilla + lemon and orange flavors in a large bowl.
3
Add the dry ingredients to the wet ingredients (I wouldn’t use a food processor, this batter should not be overmixed). Grate the carrots and apple and add them to the batter.
4
Pour the batter into the baking sheet. Bake for 40 minutes at 350 degrees Fahrenheit.
5
Let the cake cool at room temperature, then store it in the refrigerator. Make the frosting and add the frosting when the cake is cold.
6
Refrigerate for at least a few hours before eating, or even better, overnight.
