Brioche Buns recipe or Brioche bread recipes are different than regular dough recipes because of the amount of fat it contains. A regular bread recipe typically contains flour, yeast, water, salt. A brioche bread recipe is an enriched recipe that contains milk, eggs, and butter. My Brioche Buns recipe contain ¼ cup of sugar to give it an extra hint of sweetness, which is not typical in a regular bread recipe.
