This Vanilla Butter Cake is a tender, golden-yellow cake with a delicate crumb—baked in a simple 9x13 pan and drenched in a warm, tangy-sweet buttermilk sauce that soaks in as it cools. Inspired by Depression-era and Southern farmhouse baking, it’s humble, frugal, and deeply satisfying.
No mixer needed. No fancy layers. Just one bowl, one pan, and a sauce that turns a simple cake into something truly special.
