A rich, moist chocolate cake made with Coca-Cola for extra depth and tenderness, topped with a smooth, glossy chocolate frosting. This nostalgic dessert is simple to make and irresistibly fudgy.

Ingredients

1 cup Coca-Cola

1/2 cup vegetable oil

1/2 cup butter (1 stick)

3 tbsp cocoa powder

2 cups sugar

2 cups flour

1/2 tsp salt

2 eggs

1/2 cup buttermilk

1 tsp baking soda

1 tsp vanilla extract

1/2 cup butter (for frosting)

2 1/3 tbsp cocoa powder (for frosting)

6 tbsp milk or cream (for frosting)

1 tsp vanilla extract (for frosting)

3 3/4 cups confectioners sugar

Instructions

  1. Preheat oven to 350 F (180 C) and grease and flour a 13×9-inch baking pan.

  3. In a large bowl, mix sugar, flour, and salt.
  4. Pour the warm cocoa mixture over the dry ingredients and mix until combined.
  5. Add eggs, buttermilk, baking soda, and vanilla extract. Mix until smooth.
  6. Pour batter into prepared pan and bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  7. For the frosting, heat butter, cocoa powder, and milk in a saucepan until melted and smooth.
  8. Remove from heat and whisk in confectioners sugar and vanilla extract until smooth.
  9. Spread frosting over the warm cake and allow it to cool completely before serving.

Notes

Add mini chocolate chips to the batter for extra richness.

Use dark cocoa powder for a deeper chocolate flavor.

Top with chopped pecans or walnuts for added texture.

Store covered at room temperature for up to 2 days or refrigerate for up to 5 days.

Warm slices briefly in the microwave (10 to 15 seconds) before serving.
