Buttermilk Bliss Layer Cake

1. Prepare the Oven and Pans

Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans. Line the bottoms with parchment paper and grease the sides to ensure the cakes release easily later on.

2. Mix Dry Ingredients

In a large mixing bowl, sift together the cake flour, baking powder, baking soda, and salt. This step ensures that all the dry ingredients are well combined and free of lumps.

3. Combine Wet Ingredients

In a separate bowl, whisk together the melted and cooled butter, buttermilk, vegetable oil, vanilla extract, and egg yolks. Make sure the buttermilk and egg yolks are at room temperature to help the mixture come together smoothly.

4. Whip Egg Whites

Using a stand mixer, whip the egg whites with a pinch of cream of tartar until they become frothy. Gradually add the granulated sugar and continue whipping until stiff peaks form. This process stabilizes the egg whites, giving your cake a light and airy texture.

5. Combine Dry and Wet Ingredients

Now, gently mix the dry ingredients into the buttermilk mixture until just combined. It's important not to overmix at this stage to keep the batter tender.

6. Fold in Egg Whites

Carefully fold the whipped egg whites into the batter in stages. This method keeps the batter light and airy, resulting in a fluffy cake. Be gentle and take your time to ensure the egg whites are fully incorporated without deflating them.

7. Bake the Cakes

Divide the batter evenly between your prepared cake pans and smooth the tops with a spatula. Place the pans in the preheated oven and bake for about 30 minutes. You'll know the cakes are done when a toothpick inserted into the center comes out clean.

8. Cool the Cakes

Let the cakes cool in their pans for a few minutes before transferring them to a wire rack to cool completely. This prevents them from becoming soggy from residual steam.

9. Frost and Serve

Once the cakes are cool, you can frost them with your favorite frosting or wrap them tightly for storage. Enjoy your Buttermilk Bliss Layer Cake with family and friends!
