Granola is a food consisting of rolled oats, nuts, seeds, honey or other sweeteners such as brown sugar, and sometimes puffed rice, that is usually baked until crisp, toasted and golden brown. The mixture is stirred while baking to avoid burning and to maintain a loose breakfast cereal consistency. Dried fruit, such as raisins and dates, and confections such as chocolate are sometimes added. Granola is often eaten in combination with yogurt, honey, fresh fruit, milk or other forms of cereal. It also serves as a topping for various pastries, desserts or ice cream. Muesli is similar to granola, except that it is traditionally neither sweetened nor baked.

Rolled oats are a type of lightly processed whole-grain food. They are made from oat groats that have been dehusked and steamed, before being rolled into flat flakes under heavy rollers and then stabilized by being lightly toasted.
