Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step is crucial to ensure that your cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar using an electric mixer or a whisk. Beat until the mixture is light and fluffy, which typically takes about 2-3 minutes.
Step 3: Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition. Then, incorporate the vanilla extract.
