Preheat the oven to 170 ° C fan oven.
Wash, peel and finely grate the carrots and apples.
First mix together the dry ingredients, flour, sugar, salt, baking powder and 1 teaspoon of cinnamon. Then mix in the grated carrots. Add the eggs and oil and fold in everything with a wooden spoon until the batter is even.
Line a 26 cm springform pan with baking paper and fill in the carrot batter and smooth it out. Bake in the preheated oven for about 35 minutes.
Let cool on a wire rack, remove from the mold and peel off the baking paper. Lay the bottom on a cake plate.
Stir the cream cheese with powdered sugar until creamy, spread on the base and smooth out. Decorate the cake with cinnamon and walnuts.
My granddaughter decorated it for you in autumn :-))
