Dessert in a frying pan

I just adored one delicacy as a child - a sponge roll with jam. No matter how much I tried to cook the same myself, nothing worked. And I didn't even think that this roll could be cooked in a frying pan without using an oven. Today I will share with you the recipe of this awesome dessert in a frying pan.
2 rolls come out of the specified amount of ingredients.
Let's start with making the dough. First we need to beat eggs in a mixer with a pinch of salt. Beat until the eggs are beaten into a thick, lightened foam. After that, add sugar to the eggs and beat them thoroughly again so that the sugar dissolves. We won't need the mixer anymore.
Melt 30 grams of butter and leave it to cool.
Add a little flour to the whipped air mass and gently knead so that no lumps form. When the flour is finished, add the cooled melted butter. Mix everything well. Finish the preparation of the dough for dessert by adding baking powder. Mix and proceed to baking biscuits.
For baking, we will need a frying pan with a lid. The larger the diameter, the better. I have 28 cm. Heat the frying pan, grease the bottom and a little bit of the sides with butter. Pour out half of the prepared dough and evenly distribute it over the surface. Cover with a lid. Bake at an average temperature for about 10 minutes. Readiness can be checked with a match or a toothpick, when piercing the cake, it should not remain wet. When the biscuit is ready, turn it over to the other side and bake for another minute.
Remove the hot baked sponge cake from the pan or onto food wrap or baking paper. We wrap the biscuit in a roll. Both ends of the resulting roll are also wrapped with film or paper. I like the film better, after it the biscuit becomes more obedient when wrapped.
We do the same with the second biscuit. We leave them to cool down.
At this time, we will prepare the filling. We have apricot jam and walnuts. We clean and chop walnuts. We leave a few whole nuts for decoration.
Carefully, so as not to break, unwrap the cooled biscuits and spread with jam. Sprinkle with chopped nuts and wrap the roll. Sprinkle the rolls with powdered sugar through a sieve and decorate with nuts.
Dessert is ready in a frying pan. Rolls can be stored in the refrigerator for several days. But with us they do not have time to cool down, they are scattered still warm.
