08 - Let cool completely in pan before cutting into bars.

# Expert Tips:

01 -
  • These bars come together with just three ingredients for the base and whatever you have in your pantry for topping
  • The texture is somehow both chewy and crisp with that perfect crackle when you bite through the toffee layer
02 -
  • Do not skip the step of letting the chocolate chips sit on the hot crust before spreading or they will not melt evenly
  • Cutting these while they are even slightly warm results in chocolate smeared everywhere and no clean rectangles
03 -
  • Room temperature ingredients help the dough come together faster but melted butter works fine straight from the microwave
  • Line your pan with parchment paper leaving overhang on the sides like handles for easy removal
