Preheat the Oven: Preheat your oven to 325°F (163°C). Grease and flour a Bundt pan to prevent the cake from sticking.
Mix Wet Ingredients: In a large mixing bowl, combine the melted butter and sugar. Beat until well blended. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Incorporate Dry and Wet Mixtures: Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk. Begin and end with the dry ingredients. Mix until just combined, being careful not to overmix.
Step 2: Bake the Cake
Pour the Batter: Pour the batter into the prepared Bundt pan, spreading it evenly.
Bake: Bake in the preheated oven for 60-70 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown and slightly cracked.
Step 3: Prepare the Butter Sauce
Combine Ingredients: In a small saucepan, combine the sugar, cubed butter, and water. Cook over medium heat, stirring constantly, until the butter is melted and the sugar is dissolved.
Add Vanilla: Remove from heat and stir in the vanilla extract.
