# Expert Tips:

01 -
  • You get two completely different textures in every single bite, rich and dense brownie meets chewy cookie
  • The marbled pattern makes these look like you spent hours creating something fancy when it's actually quite simple
02 -
  • Underbaking slightly is your friend here, the centers continue to set as they cool and you want them fudgy not dry
  • Completely cooling before slicing is non-negotiable, warm browkies will crumble and fall apart instead of cutting into clean squares
03 -
  • Room temperature ingredients for both layers prevent the batter from seizing or separating
  • Use a light-colored pan to prevent the edges from overbaking before the center sets
