No-Bake Cake "Delicate Crunch"

In a saucepan, whisk together eggs, vanilla sugar, sugar, cornstarch, and sour cream.

Cook over low heat, stirring constantly, until the mixture thickens.

Remove from heat, stir in the butter until smooth and silky. Let the cream cool completely.

Mix flour, sugar, and softened butter together.

Rub the mixture between your fingers until you get fine, even crumbs.

Toast the crumbs in a dry skillet over medium heat, stirring occasionally, until golden brown.

In a dish or cake pan, layer as follows: crumbs → cream → crumbs.

Repeat the layers 3–4 times, finishing with a crumb layer on top.
