Ingredients

For the Cake:

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 2 sticks (1 cup) unsalted butter
• 1 cup water
• 5 tablespoons cocoa powder
• 2 large eggs
• ½ cup buttermilk
• 1 teaspoon baking soda
• 1 teaspoon vanilla extract
• Pinch of salt

For the Buttermilk Frosting (Optional but Highly Recommended):

• 1 cup buttermilk
• ½ cup unsalted butter
• 3 cups powdered sugar
• 1 teaspoon vanilla extract
• Pinch of salt

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 the butter. Add water and cocoa powder, stirring until smooth. Bring to a gentle boil, simmer for 2-3 minutes, then remove from heat and let cool slightly.
3. Combine Dry Ingredients: In a large bowl, whisk together flour, sugar, baking soda, and a pinch of salt until evenly combined.
4. Blend Wet and Dry Ingredients: Gradually add the dry ingredients to the chocolate mixture, stirring until fully incorporated. Beat in eggs one at a time, then add buttermilk and vanilla extract. Mix until the batter is smooth and lump-free.
5. Bake the Cake: Pour the batter into the prepared 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 about 1 hour.
6. Make the Buttermilk Frosting (Optional): In a saucepan, melt butter with buttermilk over medium heat. Gradually stir in powdered sugar until smooth and glossy. Add vanilla extract and a pinch of salt, mixing well.
7. Frost the Cake: Once the cake is fully cooled, spread the buttermilk frosting evenly over the top with a spatula for a smooth finish.
8. Serve and Enjoy: Slice into squares or rectangles and serve. This cake pairs perfectly with a hot cup of coffee or a cold glass of milk!

Tips for Success

• Make Ahead: The cake can be baked a day in advance and frosted just before serving.
• Storage: Store leftovers in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.
• Frosting Variation: Skip the frosting for a lighter dessert or dust with powdered sugar for a simple finish.
