# Expert Tips:

01 -
  • The shortcut ingredient that makes these bars impossibly soft and chewy without any complicated techniques or fancy equipment
  • That perfect crackly chocolate toffee layer on top that makes people think you have been working in the kitchen for hours
02 -
  • I learned the hard way that cutting these before they are completely cool results in chocolate everywhere and bars that fall apart, so patience really pays off here
  • Using room temperature ingredients for the dough stage makes mixing so much easier, though melted butter helps everything come together regardless
03 -
  • Line your pan with parchment paper that overhangs the sides and you can lift the whole batch out easily for cleaner, prettier bars
  • Sprinkle the chocolate chips over the hot crust instead of adding them before baking to prevent them from scorching or becoming grainy
