Ingredients
For the Cake Batter
2 cups granulated sugar
1 3/4 cups all-purpose flour
3/4 cup Hershey’s unsweetened cocoa powder
1 1/2 teaspoons baking powder
1 1/2 teaspoons baking soda
1 teaspoon salt
2 large eggs (room temperature)
1 cup whole milk (or buttermilk)
1/2 cup vegetable oil (or melted canola oil)
2 teaspoons pure vanilla extract
1 cup boiling water (or hot freshly brewed coffee)
For the “Perfectly Chocolate” Frosting
1/2 cup unsalted butter (1 stick, melted)
2/3 cup Hershey’s unsweetened cocoa powder
3 cups powdered sugar
1/3 cup whole milk
1 teaspoon pure vanilla extract
Instructions
Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans, lining the bottoms with parchment paper rounds.
Whisk together the granulated sugar, all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt in a large mixing bowl.
Add the room-temperature eggs, whole milk, vegetable oil, and vanilla extract directly into the dry ingredients.
Beat with an electric hand mixer on medium speed for two minutes until the batter is smooth and well blended.
Stir in the boiling water gently with a wooden spoon or silicone spatula until fully incorporated; the batter will be very thin.
Divide the thin batter evenly between your two prepared 9-inch round cake pans.
Bake in the preheated oven for thirty to thirty-five minutes until a wooden toothpick inserted into the center comes out clean.
Cool the cakes in their pans on wire racks for ten minutes before turning them out onto wire racks to cool completely.
Prepare the frosting by stirring the melted butter and cocoa powder together in a medium bowl until smooth.
Alternately beat in the powdered sugar and milk on medium speed, adding the vanilla extract until a creamy, spreadable consistency is reached.
Place the first cake layer on a serving platter and spread a thick layer of frosting over the top.
Top with the second cake layer and frost the top and sides evenly with an offset spatula, garnishing with cocoa dust if desired.
Why This Recipe Works
Stirring boiling water into the cocoa at the end blooms the chocolate flavor and produces an exceptionally tender, light crumb.
Using vegetable oil instead of creaming butter ensures the cake stays incredibly moist even when chilled in the refrigerator.
The combination of baking soda and baking powder provides dependable leavening that supports the rich, dark layers without sinking.
The simple cocoa-and-melted-butter frosting is silky, pipeable, and easy to spread without tearing delicate cake edges.
Tips for Best Results
Do not be alarmed by the thin consistency of the raw batter; it is supposed to be runny, which is the secret to its signature moisture.
Swap the cup of boiling water for hot freshly brewed coffee, which intensifies the chocolate notes without imparting any coffee taste.
Ensure both cake rounds are completely cool before frosting to prevent the creamy butter-based frosting from melting and sliding off.
Use parchment paper at the bottom of the cake pans to guarantee that the moist layers release cleanly and easily every single time.
Variations & Substitutions
For an ultra-dark and bittersweet profile, substitute standard cocoa powder with Dutch-process or dark cocoa powder.
If you love sweet contrast, pair the dark chocolate layers with a homemade cream cheese frosting, peanut butter frosting, or caramel drizzle.
To make cupcakes instead of a layer cake, divide the batter among twenty-four lined muffin cups and bake at 350°F (175°C) for twenty to twenty-two minutes.
For a dairy-free version, use unsweetened almond milk or oat milk and replace the butter in the frosting with plant-based stick butter.

Can I freeze this cake?

Why did my cake sink slightly in the center?
