If you’re a fan of indulgent chocolate desserts, this Texas Sheet Cake recipe is about to become your go-to treat. Moist, rich, and topped with a luscious chocolate glaze, this iconic cake is a crowd-pleaser for any occasion.
Preheat your oven to 350°F. Grease a 9x13-inch sheet pan or line it with parchment paper. In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt. In a saucepan, melt the butter, then stir in cocoa powder and water. Bring to a gentle boil, then pour over the dry ingredients, mixing until combined. Add the buttermilk, eggs, and vanilla extract, mixing until smooth.
Pour the batter into the prepared sheet pan, spreading it evenly. Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
While the cake bakes, melt the butter in a saucepan over medium heat. Stir in cocoa powder and milk, then bring to a gentle simmer. Remove from heat and whisk in powdered sugar and vanilla extract until smooth.
