Do you have butter on Chelsea buns?

Yes, butter is traditionally used in Chelsea buns. Chelsea buns are a type of sweet yeast bun that is popular in the United Kingdom. They are made with a sweet yeast dough that is rolled up with currants and then baked. The buns are then brushed with butter and sprinkled with sugar before being baked again. The butter helps to give the buns a rich flavor and a golden brown color.
