A reliable, moist, and tender classic vanilla birthday cake with rich vanilla buttercream. This recipe uses simple ingredients and a specific mixing method to ensure maximum moisture and flavor, coming together in under 45 minutes.
Ensure all ingredients (butter, eggs, buttermilk) are at room temperature for best results. Do not overmix the batter once flour is added to avoid a tough cake. Spoon and level flour for accuracy. If buttermilk is unavailable, substitute with 1 cup milk plus 1 tablespoon lemon juice or vinegar, rested for 5 minutes.
