Sugar and Plumm A La Mode Kit
How to win friends and influence people: Wrap up a semi-custom brownie à la mode kit (choose from chocolate-fudge brownies, chocolate-chip blondies, or both, plus two sauces—salted caramel, chocolate fudge, or butterscotch). Show up at the front door with a gallon of ice cream and a smile. (It even works on in-laws and crabby, complain-y neighbors!)
