Butter Cow


In 1911, J.K. Daniels sculpted the Fair's first butter cow and was succeeded by J.E. Wallace of Florida. In 1957, Earl Frank Dutt of Illinois took over the sculpting duties. Norma “Duffy” Lyon of Toledo, Iowa, began sculpting in 1960, becoming the fourth person and first woman to sculpt the Fair's butter beauties.

In 2006, after 15 years of apprenticing with Duffy, Sarah Pratt of West Des Moines became the Fair's fifth butter sculptor. In addition to her first Butter Cow, Pratt also crafted Superman of Superman Returns (Norwalk, Iowa, native Brandon Routh, who starred as the Man of Steel) and "Mr. State Fair" Bill Riley (in honor of his 60th Fair).

The Butter Cow starts with a wood, metal, wire and steel mesh frame and about 600 lbs. of low moisture, pure cream Iowa butter. Once inside the 40-degree cooler, layers of butter are applied until a life-size butter cow emerges - measuring about 5-1/2-ft high and 8-ft long. Each year, much of the butter is recycled and can be reused for up to 10 years.

A real dairy cow weighs more than 1,000 pounds, but the butter version comes in at around 600 pounds. Did you know the butter cow would butter about 19,200 slices of toast and take an average person two lifetimes to consume?

In addition to the Butter Cow, a companion sculpture also graces the Agriculture Building coolers.

Nothing Could Be 'Butter' in 2023 Than Iconic Iowa Athletes

The iconic Iowa State Fair butter cow will have some very important Iowa athletes to share the cooler with this year. Long time Iowa State Fair butter sculptor Sarah Pratt, along with her apprentices Hannah and Grace, will meticulously sculpt the likenesses of Jack Trice, Kurt Warner and Caitlin Clark. There are so many great Iowa athletes but we were only able to pick three, one from each of Iowa's public universities.

Jack Trice was Iowa State’s first African American athlete and 2023 commemorates his untimely death during a football game in 1923. His life and legacy have been an inspiration and 100-year commemoration programs include “I Will” Action Grants, a University museum exhibition and the creation of Jack Trice Way as a part his namesake stadium on the Iowa State University campus. His likeness in butter will be a testament to his impact on not only Iowa State but on college athletics across the country. The first Iowa State Fair butter cow was sculpted just 12 years before Jack Trice played football and ran track for Iowa State.

Kurt Warner is the only person to be inducted into both the Pro Football Hall of Fame and the Arena Hall of Fame. Warner graduated from the University of Northern Iowa in 1993 and was named the Gateway Conference’s Offensive Player of the Year. Like many in Iowa, he spent some time working for local grocer Hy-Vee before going to play for the Iowa Barnstormers, the Amsterdam Admirals and then the St. Louis Rams, the New York Giants and the Arizona Cardinals. An impressive resume with 208 passing touchdowns, 4 pro bowls and 12 seasons, Warner’s likeness in butter is the perfect testament to his calm, cool and collected demeanor.

Caitlin Clark, University of Iowa women’s basketball standout player, has added countless accolades and awards to her points and assists records, but nothing is more iconic of her impact as an Iowan than being recognized with a likeness in butter at the Iowa State Fair. Clark, a senior from West Des Moines, attended Dowling Catholic High School. She is the first player in Division 1 women’s basketball history to record more than 1,000 points and 300 assists in the same season. In 2023, Caitlin was named consensus National Player of the Year, Academic All American and Collegiate Female Athlete of the Year.
