About Killer Brownie:
Born in the bakery of Dayton, Ohio’s beloved Dorothy Lane Market in the early 1980s, Killer Brownie began with one seriously indulgent creation: a rich, fudgy, double-layered brownie with a thick ribbon of gooey caramel and pecans. What started as a local cult favorite has grown into a nationally loved dessert brand, known for its signature layers, decadent flavors and unapologetically over-the-top treats. Today, Killer Brownie is available at grocery retailers nationwide and at killerbrownie.com.
