Kruse was diagnosed with cancer in 1951 and died within 8 weeks. His sons Ed and Howard took over leadership of the company. By the 1960s, the company completely abandoned the production of butter and began focusing solely on ice cream. After many years of selling ice cream only in Brenham, the company began selling its ice cream in the Houston area, eventually expanding throughout most of Texas including the Dallas–Fort Worth metroplex and the state capital of Austin. By the end of the 1970s, sales had quadrupled, and by 1980 the creamery was producing over 10 million gallons (37,850,000 liters) of ice cream per year, earning $30 million annually.
