Preheat Oven: Preheat your oven to 350°F (175°C).
Cream Butter and Sugar: In the bowl of an electric mixer, cream together the butter and sugar until light and fluffy.
Add Eggs and Vanilla: Incorporate the eggs one at a time, then mix in the vanilla extract.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
Mix Dry with Wet Ingredients: Gradually add the dry ingredients to the creamed mixture, mixing just until combined.
Prepare the Pan: Line a 10x15 inch pan with parchment paper and lightly grease it.
Spread the Batter: Evenly spread the batter in the prepared pan.
Bake: Bake in the preheated oven for 13-15 minutes, or until a toothpick inserted into the center comes out clean.
Recipe Notes:
If you are using salted butter, omit the additional salt from the recipe to balance the flavors.
Ensure all ingredients are at room temperature to help them blend more uniformly.
