This classic vanilla butter cake is soft, rich, and deeply comforting—taken to another level with a warm buttermilk sauce that soaks right into the cake. It’s the kind of old-fashioned dessert that tastes even better the next day.

💡 Why This Cake Stands Out
The buttermilk sauce seeps into the cake, making it incredibly moist, buttery, and slightly caramelized—almost like a cross between a cake and a pudding.
🧊 Storage Tips
- Store covered at room temperature for 2 days, or refrigerate up to 5 days
- Reheat slightly before serving for the best texture
❓ FAQ
Can I use regular milk instead of buttermilk?
You can add 1 tbsp vinegar or lemon juice to 1 cup milk as a substitute.
Why does the sauce foam?
The baking soda reacts with the buttermilk, creating a light, airy texture in the sauce.
Can I add toppings?
Yes—pecans, coconut, or even a scoop of vanilla ice cream work beautifully.
