Ingredients
Scale
2 cups all-purpose flour
2 cups granulated sugar
1/2 tsp salt
1 tsp baking soda
1/2 cup sour cream
2 large eggs
1 cup unsalted butter
1 cup water
1/4 cup unsweetened cocoa powder
1 tsp vanilla extract
For the frosting:
1/2 cup unsalted butter
1/4 cup unsweetened cocoa powder
1/4 cup milk
3 1/2 cups powdered sugar
1 tsp vanilla extract
1 cup chopped pecans (optional)
Instructions
Preheat oven to 350°F (175°C). Grease and flour a 13×18-inch sheet pan.
In a large bowl, whisk together flour, sugar, salt, and baking soda. Set aside.
In another bowl, whisk together sour cream and eggs. Set aside.
In a saucepan over medium heat, combine butter, water, and cocoa powder. Bring to a boil, then remove from heat.
Pour the hot cocoa mixture into the dry ingredients and mix well.
Stir in the sour cream and egg mixture, followed by the vanilla extract, and mix until smooth.
Pour the batter into the prepared sheet pan and spread evenly.
Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
While the cake is baking, prepare the frosting: In a saucepan, melt the butter over medium heat. Stir in cocoa powder and milk and bring just to a boil. Remove from heat.
Whisk in powdered sugar and vanilla extract until smooth. Stir in chopped pecans if using.
Pour the warm frosting over the hot cake and spread quickly and evenly.
Allow the cake and frosting to cool completely before slicing and serving.
Notes
Frost the cake while it’s still warm to help the frosting soak in slightly for extra richness.
Omit pecans if you prefer a nut-free version.
Store leftovers covered at room temperature for up to 3 days.
