During the month of October, Voodoo Doughnut will be raising money for the National Brain Tumor Society by donating a portion of the proceeds of its popular Mango Tango doughnut.

The special doughnut was created by former Voodoo Doughnut CEO Robert “Lobster” Ludwig, who was diagnosed with brain cancer in 2013 and passed away in October 2015. Voodoo Doughnut honors Ludwig’s legacy with the fundraiser.

“Most of us have been effected by cancer in some way or another. Teaming up with an organization that hits so close to home reminds us of this scary impact. We hope to continue spreading awareness and funds in honor of Robin,” says Voodoo Doughnut co-founder, Tres Shannon.

The Mango Tango is a raised yeast doughnut filled with mango jelly and topped with vanilla frosting and Tang dust. Voodoo Doughnut locations across the country will participate in the fundraiser.

“The National Brain Tumor Society is honored to partner with Voodoo Doughnut. The Mango Tango is not only raising crucial funds to support our mission of finding better treatments and, one day, a cure for brain tumors, but it’s also raising invaluable awareness. With no known prevention or early detection methods, few available treatments, and no existing cure, as a community we can’t afford to not take action,” says Lauren Gainor of the National Brain Tumor Society.
