Preheat Oven: Set your oven to 350°F (175°C) and prepare two round cake pans by greasing them or lining them with parchment paper.

Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, sugar, baking powder, and salt.

Cream Butter and Sugar: In another bowl, beat the softened unsalted butter until creamy. Gradually add the sugar, beating for about 4 minutes until light and fluffy.

Add Eggs and Vanilla: Incorporate eggs one at a time, mixing well after each addition. Stir in vanilla extract.

Mix Wet and Dry Ingredients: Alternately add the dry ingredients to the butter-sugar mixture, starting and ending with the dry mix.

Bake: Pour the batter into prepared pans and bake for 25-30 minutes, or until a toothpick comes out clean.

Cooling: Allow the cakes to cool in pans for a few minutes before transferring to a wire rack.
