A Guinness World Records adjudicator was on hand to certify the cupcake's girth. It was more than eight times the size of the previous record holder.
The colossal cupcake took 12 hours to bake and included 800 eggs and 200 pounds each of sugar and flour.
Slices of the cupcake were served in exchange for donations to the Susan G. Komen for the Cure breast cancer organization.
Ryan Abood, owner of New Hampshire-based Gourmetgiftbaskets.com who made the cupcake, told the Detroit Free Press that it clocked in at an estimated 2 million calories.
