Description

This Fluffy Chocolate Cake recipe is the ultimate treat for chocolate lovers—light, moist, and rich with deep cocoa flavor. Made from scratch with buttermilk, oil, and a touch of hot coffee to enhance the chocolate, this cake is perfect for birthdays, holidays, or any time you’re craving a decadent yet airy dessert. Topped with creamy chocolate frosting, it’s a guaranteed crowd-pleaser.


Ingredients

For the cake:

All-purpose flour

Unsweetened natural cocoa powder

Baking powder

Baking soda

Salt

Granulated sugar

Eggs

Buttermilk

Warm water or hot coffee

Vegetable oil

Pure vanilla extract

For the frosting:

Unsalted butter

Confectioners’ sugar

Unsweetened cocoa powder

Heavy cream or milk

Vanilla extract

Salt


Instructions

  • Preheat oven to 350°F. Grease and line two 9-inch round cake pans.
  • In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  • In another bowl, mix eggs, buttermilk, oil, and vanilla. Gradually add dry ingredients.
  • Stir in warm water or coffee—batter will be thin, which helps create a fluffy texture.
  • Divide batter evenly between pans and bake for 30–35 minutes, until a toothpick inserted comes out clean.
  • Cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
  • For frosting: Beat butter until smooth, add cocoa and powdered sugar alternately with cream. Stir in vanilla and a pinch of salt.
  • Frost cooled cake layers generously and decorate as desired.

Notes

  • Add espresso powder to intensify chocolate flavor.
  • Raspberry jam or peanut butter makes a great layer filling.
  • Use dark chocolate ganache instead of frosting for a richer finish.
  • For cupcakes, bake 18–22 minutes.
  • Store frosted cake at room temperature (2 days) or fridge (5 days). Freeze slices up to 2 months.
  • Buttermilk substitute: 1 cup milk + 1 tbsp vinegar or lemon juice.
  • Coffee enhances chocolate without adding coffee flavor.
