Few desserts bring more joy to my family than a towering, classic vanilla layer cake, built from three fluffy layers and finished with clouds of silky buttercream. This recipe always turns out moist and tender, with just the right level of vanilla sweetness. It is a showstopper for birthdays or any special dinner.
From the very first time I baked this for my sister’s birthday, it has been the most requested cake for every family celebration. I love watching everyone gather around as I slice that first giant piece and serve it up with big smiles all around.

- Unsalted butter: Creates richness and moisture Use it at true room temperature so it creams properly
- Vegetable oil: Locks in softness A neutral pick like canola or sunflower works best
- Sugar: Sweetens and tenderizes Opt for fine granulated so it beats in thoroughly
- Vanilla extract: Gives that classic flavor Go for a pure extract and use a tablespoon as it really shines here

- Milk: Helps create a moist tender crumb Whole milk adds an extra bit of flavor and moisture
