Baking and Cooling

  1. Bake the brownies in the preheated oven for 50-55 minutes, or until an inserted toothpick comes out dry or almost dry.
  2. Cool the brownies fully (at least 2 hours) before slicing for clean, even cuts.
  3. Store leftovers at room temperature in an airtight container.

Notes

  1. Cookie layer and brownie batter can also be boxed. If so, follow instructions on the packaging.
  2. Semi-sweet chocolate can be substituted for dark chocolate. However, chocolate that's more than 60% cocoa is not recommended.
  3. Recipe can be halved and made in a 9x9 inch pan - bake time will be about the same or slightly shorter.
