Note: Adjustments are needed when baking at high altitudes. Common cookie recipe adjustments are needed to help avoid spreading and may include slight increase in baking temperature, slight decrease in leavening agents (e.g., baking powder and baking soda), fat, and/or sugar, as well as slightly increasing fluid ingredients and flour. Consult online resources to adjust this and other baking recipes.
