    Study Notes

    • Cookie spread refers to the expansion of a cookie beyond its original shape during baking.
    • Factors that influence spread include ingredient selection, formula processes, and baking conditions.

    Factors Affecting Spread

    • Sugar type and amount: smaller granules of sugar create more spread than larger granules due to increased dispersion in dough and prevention of gluten development.
    • Creaming time: increased creaming promotes spreading by incorporating air into the dough, which expands when heated.
    • Chemical leavening agents: release gases during baking, creating a lighter cookie that spreads outward.
    • Baking temperature: lower temperatures delay starch gelatinization and protein coagulation, promoting spread.
    • Dough temperature: warmer dough spreads more than colder dough.
    • Flour type: softer flour with lower protein content allows more spread.
    • Pan greasing: decreases spread resistance, allowing for more spread.

    Limiting Spread

    • Larger sugar granules: decrease air incorporation into the dough, limiting spread.
    • Less chemical leavening: reduces gas release, decreasing spread.
    • Toughening ingredients: increasing flour content or using stronger flour limits spread.
    • Higher baking temperatures: not recommended, as it can lead to uneven cooking and burning, but it can limit spread if used with caution.
