"Creaming" is a baking technique used to mix butter and sugar together until the mixture becomes light and fluffy. This process incorporates air into the mixture, which helps to create a lighter texture in baked goods like cookies and cakes. It's important to use softened butter for the best results, as it blends more easily with the sugar. During the creaming process, you typically start by beating the butter and sugar together with a mixer or a wooden spoon. Once the mixture is fluffy and pale in color, you can add other ingredients like eggs or flour. Proper creaming is essential for achieving the right consistency and flavor in your baked treats.
