Apple Crumble Cake

To prepare the apple crumble cake, start with the apple sauce: peel the apples, cut them into quarters and remove the core 1, you will get about 220 g. Cut them into pieces 2 and pour them into a saucepan 3.

Add granulated sugar 4, muscovado sugar 5, cinnamon, water and lemon juice 6.

Cook over medium-low heat for about 15 minutes, stirring with a spoon from time to time until the apples are cooked 7. Transfer the cooked apples into a jug 8 and blend with an immersion blender 9.

You have to obtain a smooth and homogeneous puree 10. Cover with cling film 11, let it cool and then transfer it to the refrigerator until use. Now take care of the crumble: in a bowl pour the oat flakes and almond flour 12.

Add the salt and sugar 13, then pour in the melted butter 14 and the coarsely chopped walnuts 15. Mix well to combine the ingredients.

Distribute the crumble on a baking sheet lined with parchment paper 16 and put in the freezer for 2 hours. Move on to the preparation of the sour cream: in a bowl pour the fresh cream, the vinegar 17 and the milk 18.

Mix with a whisk 19 and leave at room temperature for 20 minutes, without covering it. After this time, cover with cling film and put in the refrigerator until use. At this point, dedicate yourself to the dough: peel and cut the apples to obtain about 220 g, reduce them into thin slices, about 3 mm thick 21.

Put them in a bowl and set aside 22. In the bowl of a planetary mixer equipped with a leaf, pour the butter at room temperature and the sugar 23, then turn on at medium-high speed. Once you have obtained a creamy consistency, turn off the machine from time to time to scrape the dough remaining on the edges with a spatula. Pour in the eggs, one at a time 24.

Then pour 95 g of sour cream 25, the vanilla extract 26 and 200 g of apple sauce, previously prepared. Separately, mix the flour with the baking powder, baking soda and salt 27.

Mix with a spoon 28 and add the powders in the planetary mixer 29. Once everything is mixed, lower the speed and incorporate the apples 30.

Complete with coarsely chopped walnuts 31. The dough is ready 32, pour it into a hinged mold with a diameter of 21 cm, buttered and floured. Level the dough well with a spatula 33.
