CHICAGO — Battle Bars and Stella Blue Coffee have partnered to introduce a new caffeinated protein bar: Dark Chocolate Espresso Battle Bar.

Each bar features 17 grams of protein and 100 mg of caffeine. The bars also are made without artificial sweeteners, fillers or canola oil.

“We partnered with Battle Bars to bring our fans a delicious, caffeinated protein bar that delivers real fuel,” said Dan Katz, founder of Stella Blue Coffee. “Made with Stella Blue Coffee, the Dark Chocolate Espresso Bar is my go-to before the studio, the gym, or when I’m chasing Stella and my kids around the house. Hope you guys love it as much as I do.”
