Ingredients
For the Cake:
2 cups all-purpose flour
2 cups granulated sugar
3/4 cup unsweetened dark cocoa powder
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
1 cup buttermilk
1/2 cup vegetable oil
2 large eggs
1 teaspoon vanilla extract
1 cup boiling water
For the Frosting:
1/2 cup unsalted butter
2/3 cup dark cocoa powder
3 cups powdered sugar
1/3 cup milk
1 teaspoon vanilla extract
Pinch of salt
Step-by-Step Instructions
Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
In a large mixing bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
Add buttermilk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix on medium speed until just combined.
Carefully pour in the boiling water and mix on low speed until the batter is smooth. The batter will be thin – this is normal.
Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely in the pan before frosting.
For the frosting, melt butter in a saucepan over medium heat. Whisk in cocoa powder until smooth.
Remove from heat and stir in powdered sugar, milk, vanilla, and salt. Beat until smooth and spreadable.
Spread the frosting evenly over the cooled cake. Let set for 30 minutes before serving.
Expert Tips
Use high-quality dark cocoa powder for the deepest, richest flavor. The boiling water helps bloom the cocoa, enhancing its chocolate intensity.
For an even more sophisticated flavor, add 1/2 teaspoon of espresso powder to the dry ingredients – it amplifies the chocolate notes without making the cake taste like coffee.
This cake pairs wonderfully with fresh berries or a scoop of vanilla ice cream. It’s also perfect for making ahead – the flavors develop even more richness overnight.

Frequently Asked Questions
Can I make this cake ahead of time?
Absolutely! This cake actually tastes better the next day as the flavors have time to meld. Store it covered at room temperature.
What makes this cake “less sweet”?
We use a higher ratio of cocoa to sugar and a dark chocolate frosting that’s balanced rather than overly sweet, creating a more sophisticated dessert experience.
Can I freeze this sheet cake?
Yes, both the unfrosted cake and frosted cake freeze well. Wrap tightly in plastic wrap and freeze for up to 3 months.
