Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9x13-inch sheet pan or line it with parchment paper.

Step 2

In a large mixing bowl, sift together the flour, sugar, cocoa powder, salt, and baking soda. Set aside.

Pour the butter mixture into the dry ingredients and stir until combined.

In a small bowl, whisk together the buttermilk, vanilla extract, and eggs. Add this mixture to the batter and stir until smooth.

Step 6

Pour the batter into the prepared sheet pan, spreading it out evenly.

Step 7

Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.

Step 8

While the cake is baking, prepare the glaze: In a medium saucepan, melt the butter over medium heat. Stir in the cocoa powder and milk, whisking until smooth.

Step 9

Remove the glaze mixture from heat, then stir in the powdered sugar and vanilla extract until no lumps remain.

Step 10

Once the cake is out of the oven, allow it to cool slightly for 5-10 minutes. Pour the warm glaze over the cake, spreading it out evenly with a spatula.

Step 11

Let the glaze set at room temperature before slicing and serving. Enjoy your homemade chocolate sheet cake!
