Instructions
The Cake
Preheat the oven to 350℉ (180℃).
Spray a 13×18-inch sheet pan or 11×16 jelly roll pan with cooking oil and line it with parchment paper. Set aside.
Heat the butter, water, and cocoa in a large saucepan on medium-high heat and bring it to a boil.
Remove the pan from the stove, stir in the brown and granulated sugar, then follow with the flour, baking soda, and salt. Mix until well blended.
Next, add the eggs, vanilla extract, and sour cream. Mix with a hand-held mixer or whisk until thoroughly combined.
Pour the cake batter into the prepared pan. Bake in a preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Let it cool for about 20 minutes.
Chocolate Frosting
Heat milk, cocoa, and butter in a medium saucepan, bring it to barely a boil, then immediately remove it from the heat.
Stir in the confectioners' sugar and vanilla, and mix until blended. Spread the frosting over the warm cake.
Sprinkle with toasted pecans if desired. If it's for an easy birthday cake, sprinkles are festive.
Notes
Adjust bake time according to the sheet pan's size. For a thicker cake, use a smaller pan, but if you want a larger, but thinner cake, the size in the recipe is perfect.
Toasted walnuts work fine if you live somewhere pecans are harder to find. Spreading a cup of mini marshmallows on the top for the last 5 minutes of baking time is also great.
