Ingredients
For the Cake
- 2 cups all-purpose flour
- 2 cups sugar
- 1 cup butter
- ¼ cup cocoa powder
- 1 cup water
- ½ cup buttermilk
- 2 eggs
- 1 tsp baking soda
- 1 tsp vanilla extract
- ½ tsp salt
For the Warm Chocolate Frosting
- ½ cup butter
- ¼ cup cocoa powder
- 6 tbsp milk
- 3 cups powdered sugar
- 1 tsp vanilla
- Whole pecans (as many as needed to cover the top like the picture)
Instructions
1. Prepare the Cake Batter
- Preheat oven to 180°C (350°F).
- Grease a large rectangular sheet pan.
- In a bowl, combine flour, sugar, and salt.
- In a saucepan, melt the butter with cocoa powder and water. Bring to a gentle boil.
- Pour this hot mixture over the flour mixture and mix well.
- Add buttermilk, eggs, baking soda, and vanilla.
- Mix until smooth.
2. Bake the Cake
- Pour the batter into the sheet pan.
- Bake for 18–22 minutes, until a toothpick comes out clean.
- Leave the cake in the pan — do NOT remove.
3. Make the Warm Chocolate Frosting
- In a saucepan, melt butter, cocoa powder, and milk.
- Bring just to a simmer.
- Remove from heat and whisk in powdered sugar and vanilla until smooth.
4. Frost the Cake
- Pour the warm frosting over the hot cake.
- The heat helps the glaze spread beautifully and become shiny like in your picture.
- Immediately place pecans evenly all over the top while frosting is still warm.
5. Cool and Serve
Let the cake cool until the frosting sets. Cut into squares and enjoy!
