Well---- if you are bringing a cooler, then you could certainly bake brownies, package in squares for single servings... freeze those and bring along, too.

If you are at Leverick, Bucks store has ice cream.., and yes, you can get it back to the boat before it melts.

Brownie ice cream sandwiches-- Choc chip cookie ice cream sandwiches..... ummmmmmmmmm

Breeze.
