Sifting Dry Ingredients – Sift dry ingredients like flour, baking powder, baking soda, and cocoa powder. Getting air into them helps make for fluffier cookies. To sift, simply combine your dry ingredients and pour into in a fine-mesh strainer. Tap or shake the strainer until everything’s in your bowl. Even if sifting is not called for, you can whisk the dry ingredients for 30 seconds to fully combine.
Creaming Butter and Sugar – Unlike stirring or mixing, creaming isn’t about combining ingredients, it’s about aerating them. Creaming creates air pockets that expand in the oven, making the dough tender. When you add sugar, that process is more effective. Sugar crystals are formed and the air is efficiently added to the butter and sugar mixture. Butter beats up fluffiest at room temperature, or when slightly softened.
Eggs – Eggs should be added at room temperature. They add moisture to the air pockets and flavor to the dough. To quickly warm eggs, place them in a bowl of warm water for a few minutes. After the eggs have been added you should also add the vanilla extract or sometimes milk (also room temperature) if the recipe calls for it.
