Peel and dice the apples, then set aside.
In one bowl, mix all the dry ingredients: flour, sugar, cinnamon, cloves, baking powder, and chopped walnuts.
In a separate bowl, mix all the wet ingredients: yogurt, eggs, melted butter, vanilla, and brandy.
Combine the dry ingredients with the wet ingredients, mixing until a thick batter forms.
Fold in the diced apples, ensuring they are evenly distributed.
Butter a 24cm round cake pan and sprinkle it with a little flour.
Pour the batter into the pan, pressing it down to ensure it is evenly spread.
