In a deep bowl, whisk the eggs together with the sugar. When the volume increases, add the oil and flour. Stir well and transfer the mixture to a round pan with a mechanism (No. 28) well greased and with baking paper. Bake in a preheated oven at 180 degrees for about 15-20 minutes. In a saucepan over high heat, heat the water and bring the apples to a boil together with the sugar. When the apples are cooked for about 10-15 minutes, take them out of the bowl and mash them with a fork, add the sugar and steamed gelatin. Stir, and place this mixture as a layer on the sponge cake (which has already cooled completely) in the pan. In the same water in which the apples were boiled, add the sugar, and on the side, whisk the 3 puddings with a little water so that you can dissolve them. Cook the puddings until you get a thick and smooth cream. Set aside and slowly transfer the pudding to the pan over the layer of mashed apples. Allow the cake to cool completely in the refrigerator. Garnish with whipped cream, crushed walnuts and dried apples.
