Nougat Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat the oven to 350°F (175°C).
In a bowl, combine milk, egg whites, and vanilla extract.
Pour the mixture into two cake pans and bake until golden.
For the filling, mix chopped almonds, sour cream, sugar, and lemon juice in a saucepan.
Cook the mixture over low heat until it begins to thicken.
Let the filling stand for an hour before using.
