Prepare the dough: In a large bowl, combine flour, sugar, salt, and yeast. Add lukewarm milk, melted butter, and egg. Mix until a dough forms.
Knead the dough: Knead the dough on a lightly floured surface for 5-7 minutes until smooth and elastic. Place in a greased bowl, cover, and let rise for 1 hour.
Prepare the topping: In a saucepan, melt butter, sugar, and honey. Add sliced almonds and stir to coat.
Assemble the cake: Roll out the dough into a rectangle and transfer to a baking sheet. Spread the almond topping evenly over the dough. Let it rise for 10 min.
Bake the cake: Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until golden brown.
Prepare the filling: In a bowl, whip heavy cream with powdered sugar and vanilla extract until stiff peaks form.
Assemble the cake: Once the cake is cooled, slice in half horizontally. Spread the whipped cream filling over the bottom layer and top with the other cake layer.
Cut into squares and serve.
