How to make buns with pudding and blueberries step by step

Step 1 - preparing the yeast starter

• Crumble the yeast into a bowl, add sugar and mix together.
  15 g fresh yeast, 1 teaspoon sugar
  
• Pour in the milk (it must not be too hot!) and mix until you get a uniform liquid.
  125 ml milk
  
• Cover the bowl with the starter with cling film or a cloth and set aside in a warm place (without drafts) for about 20 minutes.
• The starter is ready when it visibly puffs up and thickens.
  

Step 2 - preparing the dough for sweet buns

• Pour the flour into a large bowl and add the remaining ingredients, then pour in the yeast starter.
  300 g all-purpose flour, 50 g sugar, 1 egg, 40 g butter
  
• Knead together into an elastic and smooth dough - I do this with a mixer.
  
• Cover the bowl with the dough with cling film or a cloth and set aside in a warm place (without drafts) for about an hour to rise.
  

Step 3 - preparing the pudding for the filling

• Pour about half a glass of milk (intended for the pudding) and add the pudding powder and sugar (if using) to this reserved portion - mix.
  1 package vanilla pudding, 380 ml milk, 3 teaspoons sugar
  
• Pour the rest of the milk into a saucepan, add the mixed pudding and heat together (stirring frequently) until you get a thick pudding.
  
• Cover the pudding with cling film, ensuring the film touches the surface of the pudding, and set aside to cool.
  

Step 4 - preparing the buns

• Once the dough has doubled in volume, briefly knead it by hand.
  
• Remove the dough onto a lightly floured countertop and lightly knead it again.
  
• Roll out the dough into a thin flat cake about 0.5 cm thick.
  
• Spread the cooled pudding over the top of the dough.
  
• Sprinkle blueberries over the pudding.
  approx. 250-300 g blueberries
  
• Roll the dough into a log, starting from the narrower side.
  
• Cut the dough into slices to get 8 buns.
  
• Arrange the buns in a buttered and floured baking dish, then cover the dish with cling film or a cloth and leave the buns for about 30 minutes – for them to puff up and rise slightly.
  

Step 4 - baking the buns

• While the buns are rising, preheat the oven to 170℃ in convection mode or 180℃ in top/bottom heat mode.
• Remove the film from the risen sweet buns and place the dish in the oven.
• Bake the buns for about 25 minutes – until they are nicely browned.
• After baking, cool the buns.

Step 5 - preparing the icing for the buns

• Pour the powdered sugar into a bowl and add two tablespoons of milk - mix - if the icing is too thick or all the sugar has not dissolved, add a little more milk.
  100 g powdered sugar, approx 2-3 tablespoons milk
  
• Glaze the top of the buns with icing.
