Decide on a date and time for the exchange. Make one dozen for each guy in the exchange . You only need to bake for the other guys, so don't count yourself. Arrange your cookies on nice, festive-looking plates. Colored plastic wrap and ribbon are optional here, but fun.
Bars are also just fine.
Make copies of your recipe to share with the other bakers. Don't skimp on ingredients - use butter, for goodness sake. Obviously, no Chips Ahoy, Slice 'n Bake, etc. No Martha Stewart recipes. Each guy bring an extra dozen to leave out for the rest of the staff to enjoy .
