Quaker Oat Squares cereal

Quaker Oat Squares are a popular breakfast cereal recognized for their crunchy texture and toasted oat flavor. The Quaker Oats brand has a storied history dating back to 1877, founded in the United States, and has since become one of the most iconic names in American food production. The brand was originally established by Henry Parsons Crowell and became a pioneer in modern packaging and marketing for grain products.

Today, Quaker is owned by PepsiCo, a global food and beverage giant headquartered in Purchase, New York. While most of the production for the North American market takes place in US-based facilities, such as the historic mill in Cedar Rapids, Iowa, PepsiCo manages a vast global supply chain that may involve regional production centers depending on the specific market and distribution requirements. As of 2026, PepsiCo remains the ultimate owner, continuing to leverage the Quaker brand across a wide range of nutritional breakfast and snack products.
