Instructions
1. Prepare the Cake
- Preheat your oven to 350°F (175°C).
- Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.
2. Mix Wet Ingredients
- In a large saucepan over medium heat, melt 2 sticks of butter.
- Add 1 cup water and 5 tbsp cocoa powder, stirring until smooth. Bring to a gentle boil, then simmer for 2-3 minutes.
- Remove from heat and let cool slightly.
3. Combine Dry Ingredients
- In a large mixing bowl, whisk together 2 cups flour, 2 cups sugar, 1 tsp baking soda, and a pinch of salt.
4. Blend Wet and Dry Ingredients
- Gradually add the dry ingredients to the warm chocolate mixture, stirring until fully combined.
- Beat in 2 eggs, one at a time, followed by ½ cup buttermilk and 1 tsp vanilla extract. Mix until the batter is smooth and lump-free.
5. Bake the Cake
- Pour the batter into the prepared baking pan and spread evenly.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool completely in the pan on a wire rack for at least 1 hour.
6. Prepare the Buttermilk Frosting (Optional)
- In a medium saucepan, combine 1 cup buttermilk and ½ cup butter. Heat over medium, stirring until the butter melts completely.
- Gradually whisk in 3 cups powdered sugar until smooth and glossy.
- Stir in 1 tsp vanilla extract and a pinch of salt. Remove from heat.
7. Frost the Cake
