Ingredients
For the Butter Cake:
- 1 cup (2 sticks) unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 1 tablespoon pure vanilla extract
- 3 cups all-purpose flour
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup buttermilk
For the Buttermilk Sauce:
- ½ cup (1 stick) unsalted butter
- 1 cup granulated sugar
- ½ cup buttermilk
- 1 teaspoon vanilla extract
- ¼ teaspoon baking soda
Instructions
Step 1: Preheat & Prepare
Preheat oven to 325°F (165°C).
Grease and flour a Bundt pan or 9×13-inch baking dish.
Step 2: Cream Butter & Sugar
Beat butter and sugar together until light and fluffy (about 3–5 minutes).
Add eggs one at a time, mixing well after each addition.
Stir in vanilla.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together flour, baking soda, and salt.
Step 4: Alternate Mixing
Add dry ingredients to the batter alternately with buttermilk, beginning and ending with flour.
Mix just until combined — avoid overmixing.
Step 5: Bake
Pour batter into prepared pan.
Bake 55–70 minutes (depending on pan size) or until a toothpick inserted in the center comes out clean.
Let cake cool slightly in the pan (about 10–15 minutes).
Make the Buttermilk Sauce
While the cake bakes:
- In a saucepan, combine butter, sugar, and buttermilk.
- Cook over medium heat until butter melts and sugar dissolves.
- Bring to a gentle boil and cook 1–2 minutes.
- Remove from heat and stir in vanilla and baking soda (it will foam slightly).
Soak the Cake
While the cake is still warm:
- Poke small holes across the surface using a skewer or fork.
- Slowly pour warm sauce over the cake, allowing it to soak in gradually.
Let the cake absorb the sauce completely before serving.
