  • 2½ cups granulated sugar
  • 4 large eggs, room temperature
  • 3 cups all-purpose flour
  • ½ tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt
  • 1 cup sour cream, room temperature
  • ½ cup buttermilk, room temperature
  • 1 tbsp pure vanilla extract (or 2 tsp vanilla + ½ tsp almond extract for depth)

For the Vanilla Buttercream (Optional):

  • 1 cup (2 sticks) unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 2–3 tbsp heavy cream or milk
  • 2 tsp vanilla extract
  • Pinch of salt

👩‍🍳 Step-by-Step Instructions

1. Prep & Preheat

  • Preheat oven to 325°F (163°C).
  • Grease & flour three 8-inch or two 9-inch round pans. Line bottoms with parchment.

2. Make the Batter

  1. Cream butter & sugar until light and fluffy (~5 mins).
  2. Add eggs one at a time, mixing well after each.
  3. Sift dry ingredients (flour, baking soda, baking powder, salt).
  4. Mix wet ingredients (sour cream, buttermilk, vanilla).
  5. Alternate adding dry & wet mixtures to butter, starting and ending with flour. Mix just until combined—don’t overbeat!

3. Bake & Cool

  • Divide batter evenly into pans.
  • Bake 30–35 mins (round pans) or 50–60 mins (Bundt) until a toothpick comes out clean.
  • Cool 10 mins in pans, then transfer to wire racks.

4. Frost (Optional)

  1. Beat butter until creamy.
  2. Gradually add powdered sugar, then cream, vanilla, and salt. Whip until fluffy.
  3. Frost cooled cakes and stack for a “mile high” look!

🌟 Pro Tips for Success

🎂 Cake Perfection:

  • Room temp ingredients ensure even mixing.
  • Weigh flour (360g) for accuracy—don’t scoop!
  • Underbake slightly—cakes continue cooking as they cool.

🍦 Flavor Variations:

  • Lemon: Add 2 tbsp zest + 1 tbsp juice (replace buttermilk).
  • Chocolate Chip: Fold in 1 cup mini chips.

⏳ Make-Ahead Tips:

  • Unfrosted layers freeze well for 1 month (wrap tightly).
  • Frosting keeps refrigerated for 2 weeks (rewhip before using).

❓ Frequently Asked Questions

4. How do I store leftovers?

  • Room temp: 2 days (covered).
  • Fridge: 1 week (bring to room temp before serving).

5. Can I use cake flour?

Yes! Substitute 2¾ cups cake flour + ¼ cup cornstarch for lighter texture.
