Prepare the yeast cake by mixing flour, yeast, sugar, warm milk, butter, egg, and salt in a bowl.
Knead the dough until smooth, then let it rise in a warm place for about 1 hour.
Preheat the oven to 350°F (180°C). Roll out the dough and place it in a greased baking pan.
For the topping, melt butter, sugar, honey, and cream in a saucepan. Stir in the almonds and spread over the dough.
Bake for 25-30 minutes until golden brown. Let cool completely.
For the filling, heat milk in a saucepan. Whisk sugar, egg yolks, and cornstarch in a bowl. Gradually add hot milk, then return to the pan and cook until thick. Stir in vanilla and let cool.
Fold whipped cream into the cooled custard. Slice the cake horizontally and spread the filling between the layers.
Notes
Store the cake in the refrigerator. Serve chilled.
