- 2 cups granulated sugar – Adds sweetness and helps create a moist texture.
- 1½ teaspoons baking powder – Gives the cake a light lift.
- 1½ teaspoons baking soda – Reacts with the buttermilk and enhances the rise.
- 1 teaspoon salt – Balances sweetness and enhances chocolate intensity.
- 2 large eggs – Add moisture, richness, and help bind the ingredients.
- 1 cup buttermilk – The acidity helps tenderize the crumb and adds a tangy depth.
- ½ cup vegetable oil – Contributes to the cake’s incredible moistness.
- 2 teaspoons pure vanilla extract – Adds warm, aromatic flavor.
- 1 cup boiling water – Intensifies the cocoa flavor and helps bloom the chocolate.
For the Chocolate Frosting:
- 1 cup unsalted butter, softened – Forms the creamy base of the frosting.
- ¾ cup unsweetened cocoa powder – Makes the frosting rich and deeply chocolaty.
- 3½ cups powdered sugar – Sweetens and thickens the frosting to a spreadable consistency.

- Pinch of salt – Rounds out the sweetness and makes the chocolate pop.
Step-by-Step Instructions

1. Prepare the Cake Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line with parchment paper circles for easy removal.
2. Combine Dry Ingredients
In a large mixing bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. Mix well to distribute evenly.
3. Add Wet Ingredients
Add the eggs, buttermilk, oil, and vanilla extract to the dry ingredients. Mix until fully combined and smooth.
4. Add Boiling Water
Slowly pour in the boiling water, mixing on low speed until incorporated. The batter will be thin — this is key to a moist cake.
5. Bake the Cakes
Divide the batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to wire racks to cool completely.
6. Make the Chocolate Frosting
Beat the softened butter in a large bowl until creamy. Sift in the cocoa powder and mix until smooth. Gradually add the powdered sugar, alternating with the cream, beating until light and fluffy. Mix in the vanilla extract and a pinch of salt. Adjust consistency with more cream if needed.
7. Assemble the Cake
Once the cake layers are completely cool, place one layer on a serving plate. Spread a generous layer of frosting on top. Add the second cake layer, then frost the top and sides evenly.

Pro Tips for Perfect Chocolate Cake
