Baking Adjustments
2 Tbsp. scoop: Bake for 10-11 minutes. Makes 30 cookies.
3 Tbsp. scoop: Bake for 12-13 minutes. Makes 20 cookies.
4 tablespoon scoop (¼ cup): Bake for 14-15 minutes. Makes 15 cookies.
I bake with light baking sheets, so my recipe times reflect that. If your cookie sheets are dark, you may need to adjust the baking time by baking the cookies for a shorter period.
