Pop-Tarts 'Gone Nutty' Debut In Peanut Butter

Kellogg's has debuted two new Pop-Tarts flavors: peanut butter and frosted peanut butter. The "Gone Nutty" varieties, which both contain a peanut butter filling, pack a sugary punch -- the peanut butter flavor is topped with a sprinkling of sugar crystals and the frosted chocolate flavor features a frosted chocolate crust.
