For the Yeast Dough:
Warm the milk and cubed butter together in a saucepan until the butter is melted and the mixture is lukewarm.
In a large bowl, mix the flour, sugar, and salt. Crumble the yeast over the flour mixture, then pour in the lukewarm milk-butter mixture.
Using the dough hooks of a hand mixer (or a stand mixer with a dough hook), knead everything for 7 minutes until a smooth dough forms.
Cover the dough and let it rise for about 45 minutes.
For the Pudding Cream:
While the dough is rising, prepare the pudding. Heat the milk in a saucepan until it begins to boil.
In a small bowl, whisk the pudding powder with sugar and 3–4 tablespoons of the hot milk until smooth. Pour this mixture back into the saucepan, stirring constantly, and bring to a boil again until thickened.
Transfer the pudding to a bowl and cover directly with plastic wrap (so it touches the surface) to prevent a skin from forming. Let it cool completely.
Prepare the Cake Base:
Grease a 12-inch (30 cm) springform pan. Preheat the oven to 350°F (180°C).
Knead the risen dough briefly on a lightly floured surface, then roll it out into a round shape about 12 inches (30 cm) in diameter.
Place the dough in the prepared pan, cover, and let it rest for another 15 minutes.
For the Almond Topping:
In a saucepan, bring the butter, cream, sugar, and honey to a boil.
Reduce the heat and let the mixture simmer for about 2 minutes.
Remove from heat and stir in the sliced almonds.
Spoon the mixture evenly over the dough and spread it gently with a spatula.
Bake the Cake:
Bake in the preheated oven for about 30 minutes.
Right after baking, carefully loosen the edge of the springform pan. Let the cake cool completely.
Assemble the Bienenstich (Bee Sting Cake):
Once cooled, carefully cut the cake horizontally in half. Place the bottom layer on a cake plate and secure a cake ring around it.
Whip the heavy cream with cream stabilizer until stiff. Stir the cooled pudding briefly to smooth it, then fold in the whipped cream.
Spread the cream evenly over the bottom cake layer.
Pre-cut the top layer into 10–12 slices (this makes serving easier), then place it carefully on top of the cream.
Chill for at least 2 hours. Keep chilled until serving. The cake makes about 12 slices.
