That's how a record crumbles.

An Oklahoma girl sold more Girl Scout cookies than any other in the organization's history, beating the record by just 10 boxes.

Middle School student Katie Francis, of Oklahoma City, officially broke the record when she sold a staggering 18,010 boxes of cookies.

The previous record was 18,000.

Francis, who was also the national top seller in 2013, set a goal to sell 20,000 boxes and still has one more week of selling left.

Jaimie Siegal, director of marketing and communications at Girl Scouts of Western Oklahoma, said they want to wait until the selling period is over before commenting on Francis' success.

ABC Bakers and Little Brownie Bakers are the two commercial bakers licensed by Girl Scouts of the USA to produce Girl Scout Cookies.

According to the Girl Scouts, the five top selling cookies are Thin Mints (25 percent), Samoas (19 percent), Tagalongs (13 percent), Peanut Butter Sandwich (11 percent) and Shortbread (9 percent).
