Ingredients & Their Roles

For the Vanilla Cake Layers

• 2 ½ tsp baking powder – Ensures the cake rises evenly and stays fluffy.
• ½ tsp baking soda – Enhances lift and works with buttermilk for tenderness.
• ½ tsp salt – Balances sweetness and enhances flavor.
• ¾ cup unsalted butter (room temperature) – Adds richness and moisture.
• 1 ¾ cups granulated sugar – Sweetens and helps create a soft texture.
• 4 large eggs (room temperature) – Bind ingredients and contribute to structure and richness.
• 1 tbsp pure vanilla extract – Deepens the flavor profile.
• 1 cup buttermilk (room temperature) – Activates baking soda, adds moisture, and a slight tang for depth.

For the Vanilla Buttercream Frosting

• 1 cup unsalted butter (softened) – The creamy base for your frosting.
• 4 cups powdered sugar – Sweetens and thickens the frosting.
• 2 tsp vanilla extract – Gives the frosting its signature flavor.

Step-by-Step Instructions

1. Preheat & Prep

• Preheat your oven to 350°F (175°C).
• Grease and flour two 9-inch round cake pans, or line them with parchment paper circles.

2. Mix Dry Ingredients

• In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

3. Cream Butter & Sugar

• In a large bowl, beat butter and sugar together on high speed until light and fluffy (about 3–4 minutes). This adds air, ensuring a tender cake.

4. Add Eggs & Vanilla

• Beat in the eggs one at a time, mixing well after each addition.
• Stir in the vanilla extract.

5. Alternate Dry Ingredients & Buttermilk

• On low speed, add the dry mixture in three parts, alternating with buttermilk in two parts, beginning and ending with dry. Do not overmix.

6. Bake

• Divide batter evenly between pans and smooth the tops.
• Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
• Cool in pans for 10 minutes, then transfer to wire racks to cool completely.

7. Make the Frosting

• Beat butter on medium speed until creamy.
• Add powdered sugar, 1 cup at a time, beating slowly until combined.
• Stir in vanilla and salt.
• Add cream a tablespoon at a time until desired consistency is reached (smooth and spreadable).

8. Frost and Decorate

• Level cake layers if necessary.
• Place the first layer on your serving plate, spread frosting evenly on top, then add the second layer.
• Frost the top and sides, smoothing with a spatula.
• Decorate with sprinkles, piping, or candles as desired.
