First, cream the margarine with 100g sugar until fluffy, then gradually add 3 eggs.

Next, combine the flour and baking powder, sift into the sugar and margarine mixture, and mix.

Grease a baking sheet and, if desired, sprinkle with breadcrumbs.

Pour the batter into the springform pan and smooth the surface.

Bake for 15 minutes at 200°C (390°F).

Now whisk together the pudding and milk.

Mix the applesauce with a tablespoon of sugar, heat, combine with the prepared custard powder, and bring to a boil.

Pour this applesauce-pudding mixture over the baked crust and smooth it out.

Separate the remaining 3 eggs and beat the egg whites until stiff peaks form.

Mix 4 tablespoons of sugar and the egg yolks with the cream. Gently fold in the stiffly beaten egg whites.

Pour the cream-egg white mixture over the applesauce layer and smooth it out.

Bake for another 40 minutes at 200°C (390°F). Enjoy your meal!
