Copycat Costco Vanilla Cake

Step-by-Step Instructions:

Step 1: Preheat the Oven and Prepare Cake Pans
  1. Preheat your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans, tapping out any excess flour.
Step 2: Prepare the Cake Batter
  1. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
  2. Add the vegetable oil to the butter mixture and mix until well combined.
  3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined, being careful not to overmix.
Step 3: Bake the Cake Layers
  1. Divide the batter evenly among the prepared cake pans. Smooth the tops with a spatula.
  2. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
  3. Remove the cakes from the oven and let them cool in the pans for 10 minutes before transferring them to wire racks to cool completely.
Step 4: Prepare the Frosting
  1. In a large mixing bowl, beat the softened butter until smooth and creamy.
  2. Gradually add the powdered sugar, one cup at a time, beating well after each addition.
  3. Add the vanilla extract and 2 tablespoons of heavy cream or milk. Beat until smooth and fluffy, adding more cream or milk as needed to achieve the desired consistency.
