Chocolate Sheet Cake
Description
This Chocolate Sheet Cake recipe begins by mixing dry ingredients including flour, sugar, cocoa powder, baking soda, and salt. Wet ingredients—eggs, buttermilk, hot water, and vegetable oil—are incorporated to create a runny batter, which is poured into a greased 11x15-inch baking dish and baked at 350°F for about 20 minutes, until a toothpick comes out clean.
The frosting combines melted butter with cocoa powder, milk, and vanilla, whisked with sifted powdered sugar into a smooth glaze. This is poured over the warm cake and spread quickly before setting. Optional toppings like chopped nuts or sprinkles can be added immediately for extra texture and decoration.
Its sheet form yields a large quantity suitable for parties. The cake is moist with a tender crumb, complemented by a rich, glossy chocolate frosting that adheres smoothly over the top. The cake pairs well with ice cream or can be served as is for chocolate lovers.
Leftover cake stores well at room temperature for a few days or freezes up to two months. The cake may be baked ahead without frosting, then frosted just before serving.

Instructions
Cake
- Preheat the oven to 350 degrees F.
- To make the cake, mix flour, sugar, cocoa powder, baking soda, and salt in a large bowl.

Frosting
- To make the frosting, melt butter in a medium pot over low heat. Add cocoa powder, milk, and vanilla and whisk until smooth. Add powdered sugar and whisk until smooth.
