Use natural cocoa powder for classic tang and color, and be sure your buttermilk and eggs are at room temperature so the batter emulsifies smoothly. Red food coloring intensity varies by brand; adjust to achieve a vibrant but not dark hue, or use gel color sparingly. Avoid overmixing once flour is added to keep the crumb tender. If your kitchen is warm, chill frosting briefly if it gets too soft, and crumb-coat the cake before the final layer for a clean finish. For extra moisture, brush cooled layers lightly with buttermilk or simple syrup. The cake keeps covered and refrigerated for up to 4 days; bring to room temperature before serving for best texture.
