# Expert Tips:

01 -
  • They come together in under ten minutes of actual hands-on time, perfect for those oh-crap-I-forgot dessert emergencies
  • The combination of buttery cake base, melted chocolate, and crunchy toffee hits every single texture craving at once
02 -
  • Dont skip the cooling step—I once cut these too early and ended up with a delicious but messy chocolate puddle situation
  • If your toffee bits start burning before the eight minute mark is up, pull them out earlier—ovens vary wildly
03 -
  • Room temperature ingredients help the dough come together more smoothly, though melted butter is fine straight from the microwave
  • For extra toffee flavor, fold half a cup of toffee bits into the base dough before pressing it into the pan
