How to make express cinnamon buns

Step 1 - preparations

• Grease the baking pan with butter and dust with flour.
• Preheat the oven to 180 ℃ (top/bottom heat mode) or 170 ℃ (convection).

Step 2 - preparing the cinnamon buns

• Add flour to a large bowl, add the remaining dry ingredients.
  300 g all-purpose flour, 50 g sugar, 2 teaspoons baking powder, 0.5 teaspoon cinnamon, 1 pinch salt
• Add butter and egg.
  60 g butter, 1 egg
  
• Pour in almost all the milk and start mixing/kneading the dough.
  80-90 ml milk
  
• If the dough is not sticky enough, add the rest of the milk, and if it's too sticky, add a little flour (I didn't have to).
  
• Take the dough out onto a lightly floured surface and roll it out into a thin flatbread.
  
• Mix the sugar for the filling with cinnamon.
  100 g sugar, 2 teaspoons cinnamon
  
• Brush the entire surface of the dough with melted butter.
  approx 20 g butter
  
• Sprinkle the top of the dough with cinnamon sugar.
  
• Roll the dough into a log.
  
• Cut the dough into 8 portions.
  
• Arrange the buns in the prepared pan.
  

Step 3 - baking the buns

• Bake the buns for about 20-25 minutes - until they are nicely golden brown. You can also check with a toothpick to see if the dough inside is well baked.
• Cool the finished buns before frosting.

Step 4 - preparing the glaze for the buns

• Pour the powdered sugar into a bowl. Add heavy cream (regular milk can also be used) in portions and mix until you get a thick and smooth frosting.
  100 g powdered sugar, approx 35 ml heavy cream
  
• Frost the top of the buns with the icing.
