Step-by-Step Instructions
Step 1: Preheat & Prep
Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. This ensures your cake comes out effortlessly.
Step 2: Prepare the Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. This ensures an even distribution for the best texture.

Step 3: Prepare the Wet Ingredients
In a separate bowl, whisk together the buttermilk, oil, eggs, and vanilla extract. This is crucial to thoroughly mix the wet ingredients.
Step 4: Combine Wet & Dry
Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Overmixing can lead to a tough cake, so be gentle.

Step 5: Bake the Cakes
Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Be vigilant about checking for doneness to prevent over-baking.
Step 6: Cool & Level (Important!)
Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely. Leveling the cakes creates a smooth surface for frosting—a key step to a visually appealing cake.

Step 7: Prepare the Buttercream
In a large bowl, beat the softened butter until light and fluffy. Add the powdered sugar gradually, beating on medium speed until smooth and creamy. This section is important for a smooth, stable frosting.
Step 8: Frost & Decorate
Once the cakes are completely cool, frost the first layer with half the buttercream. Top with the second cake layer and frost the entire cake with the remaining buttercream. Garnish as desired. Consider using fresh berries or chocolate shavings for a beautiful look.
