4 cups peeled, cored, chopped apple, about 4-6 apples
Frosting:
¼ cup salted butter
4 tbsp pure maple syrup
2 tbsp milk
1½ cups icing sugar
Instructions
Preheat oven to 350℉. Line a 9x13 baking pan with parchment paper.
In a large bowl whisk together the eggs and sugar until light and fluffy, then whisk in the vanilla and oil.
In a separate bowl, whisk together the flour, spices, salt and baking soda.
Add the flour and apples all at once to the egg mixture. Stir with a spatula until the flour is all incorporated. Batter will be very thick.
Transfer batter to lined baking pan and spread into an even layer with a knife or offset spatula.
Bake the cake for 40-45 minutes, or until a toothpick inserted into the centre comes out clean, or with just a few wet crumbs clinging to it.
Remove the cake from the oven and place it on a rack to cool completely; don't remove the cake from the pan.
To make the frosting: Melt the butter and maple syrup in a small pan over medium heat. Add the milk, bring to a boil, and pour into a mixing bowl to cool for 10 minutes. (You can also do this in the microwave)
After 10 minutes, stir in the icing sugar.. Beat well; if the mixture appears too thin, add more icing sugar. Spread on the cooled cake.
