The pumpkin spice latte battle is heating up just in time for fall.

Starbucks and Panera are hyping reformulated versions of the popular drinks - which will include real pumpkin-in a fight to win over fans of the beverage in coming weeks.

Starbucks Corp says its version of the concoction this year will be made with real pumpkin and without caramel coloring. The change comes after blogger Vani Hari, known as the Food Babe, criticized Starbucks last year for the drink's ingredients and its lack of transparency around the issue.
