Begin by preheating your oven to 350°F (175°C). Grease and flour your baking pan, ensuring an easy release for the final masterpiece.

In a large mixing bowl, cream together 1 cup of unsalted butter and 2 cups of superfine sugar until light and fluffy. This forms the foundation for the cake’s decadent texture.

Add four farm-fresh eggs one at a time, beating well after each addition. Introduce 2 teaspoons of pure vanilla extract to infuse the batter with a heavenly aroma.

Sift 3 cups of all-purpose flour in a separate bowl to ensure a smooth, lump-free texture. Gradually fold the sifted flour into the wet mixture, alternating with 1 cup of rich buttermilk. This step guarantees a perfectly balanced consistency.

Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for approximately 45-50 minutes or until a toothpick inserted into the center comes out clean. This precise baking time ensures the ideal combination of moistness and firmness.
