To begin with, we build a water bath, where we melt butter with sugar and salt in an inner saucepan, pour in one glass of boiling water and, stirring constantly, add flour. It is necessary to stir intensively, then we will get the perfect custard dough, without lumps, shiny. Now remove from the stove, let it cool down. One by one, we drive eggs into the mass, holding a mixer in our hand – this will turn out faster and more reliable. We cover the baking sheet with parchment and spread the dough on it with a tablespoon. We leave some distance between the cakes, as they will spread out on the sheet. Bake in a preheated oven for about 20 minutes. We will get such "balls", hollow inside, which need to be filled with cream.
Cream: beat the egg with sugar with a mixer, add flour, pour in milk, bring to a boil in a water bath until it thickens. Then cool, put the vanilla and beat with a mixer with butter until smooth.
