Classic Vanilla Butter Cake with Buttermilk Sauce
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.
Ingredients
For the cake:
- 2 cups (250 g) all-purpose flour
- 1 ½ cups sugar
- ½ cup (115 g) butter (softened)
- 2 eggs
- 1 cup buttermilk
- 1 tsp vanilla extract
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
For the buttermilk sauce:
- 1 cup sugar
- ½ cup butter
- ½ cup buttermilk
- 1 tsp vanilla extract
- ½ tsp baking soda
Instructions
- Preheat oven to 180°C (350°F) and grease a baking dish or loaf pan.
- Cream butter & sugar:
Beat until light and fluffy. - Add eggs & vanilla:
Mix in eggs one at a time, then add vanilla. - Combine dry ingredients:
In another bowl, whisk flour, baking powder, baking soda, and salt. - Alternate mixing:
Add dry ingredients and buttermilk to the batter in batches, mixing gently. - Bake for 30–40 minutes
Until golden and a toothpick comes out clean.
Make the sauce (while cake bakes):
7. In a saucepan, combine sugar, butter, and buttermilk.
8. Bring to a gentle boil, then remove from heat.
9. Stir in vanilla and baking soda (it will foam slightly).
Finish:
10. Poke small holes all over the warm cake.
11. Pour the hot buttermilk sauce evenly over the cake.
12. Let it soak and cool before serving.
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.
