Notes

*Be sure to read the section in the post above on how to heat treat flour and why you should.
Storage:
Store leftovers in an airtight container in the refrigerator for up to 5 days.
They also freeze well. Cut them, but leave them in the pan. Flash freeze, then pop them in individual-sized storage bags and freeze for up to 3 months.
Tips:
  1. Make sure to use heat-treated flour in the cookie dough to make it safe for eating.
  2. Let the brownies cool completely before adding the cookie dough layer to prevent melting.
  3. Make sure you use a good brand of real chocolate chips for the ganache. They will melt better.
  4. Chill at least 8 hours or overnight for best results and clean cuts.
