Punch the dough down and transfer to an oiled surface. Using a rolling pin, roll the dough into a 16 x12 inches (40x30cm) rectangle.
With the back of a spoon or a spatula, spread 2 tablespoons (30g) of softened butter over two-thirds of the rolled dough.
Sprinkle ½ cup (50g) cheddar cheese over two-thirds of the dough.
Fold the dough like a letter into thirds, starting with the unbuttered side of the rectangle. Rotate the dough at 90° and repeat rolling the dough into a 16 x12 inches (40x30cm) rectangle.
Again, spread 2 tablespoons (30g) softened butter over two-thirds of the rectangle. Sprinkle the remaining ½ cup (50g) cheddar cheese over two-thirds of the dough.
Fold the dough like a letter into thirds, starting with the unbuttered side of the rectangle.
Cut the dough into 8 equal pieces.
Twist each piece and bring the ends together, pinch the ends and place on a parchment paper baking sheet.
Cover with a kitchen towel and let rise for 20-30 minutes.
Meanwhile, preheat the oven to 400F (200C).
Brush the buns with beaten egg and sprinkle sesame seeds on top.
Bake for 18-20 minutes or until puffed and golden brown.
