07 - Return to oven for 8-10 minutes until toppings are slightly bubbly and edges are golden.
08 - Cool completely in pan before cutting into bars.

# Expert Advice:

01 -
  • They taste like you spent hours making caramel from scratch when it really took five minutes
  • The buttery base edges get perfectly crisp while staying chewy in the center
02 -
  • Do not overbake the base during the first 15 minutes or the final texture will be crumbly instead of chewy
  • Let the bars cool completely before cutting or the chocolate will smear and the toffee will slide right off
03 -
  • Press the dough slightly thinner at the edges to prevent them from becoming too thick and hard to bite through
  • If the toffee bits are large give them a quick chop so they distribute more evenly across the top
