Buttery, chewy bars layered with rich toffee and chocolate, made with a cake mix base for easy preparation.

# What You'll Need:

→ Base Layer

01 - 1 box (15.25 oz) yellow cake mix

04 - 1 cup semi-sweet chocolate chips

03 - Press dough evenly into prepared baking pan to form base layer.

# Expert Advice:

  • The cake mix hack creates a buttery, tender base without measuring flour or leaveners
  • These bars come together in under 10 minutes of active prep time
02 -
  • Letting the hot base sit for 2-3 minutes after adding chocolate chips is the secret to easy spreading
  • Cutting these bars before they are completely cooled will result in a messy, gooey disaster
03 -
  • Room temperature ingredients mix more evenly and create better texture
  • The toothpick test does not work here since these should remain slightly chewy
