05 - 1/4 cup unsweetened cocoa powder
06 - 1 cup boiling water

10 - 1 teaspoon baking soda

→ Frosting

11 - 3/4 cup unsalted butter
12 - 1/4 cup unsweetened cocoa powder
13 - 1/2 cup milk
14 - 1 teaspoon vanilla extract
15 - 3 cups powdered sugar
16 - 1 cup chopped pecans

# Instructions:

01 - Preheat oven to 350°F and grease a half sheet pan (13x18 inches) with nonstick spray. Set aside.
02 - In a large mixing bowl, stir together the flour, sugar, and salt. Set aside.
03 - In a saucepan over medium heat, melt the butter. Whisk in cocoa powder until thoroughly combined. Stir in boiling water and increase heat to medium-high. Bring to a boil and let boil for 30 seconds before turning off heat.
04 - Pour the hot cocoa mixture over the flour mixture and stir to combine, scraping the bottom and sides well.
05 - In a medium bowl, whisk together buttermilk, eggs, baking soda, and vanilla extract. Stir the buttermilk mixture into the combined chocolate and flour mixture.
06 - Pour the batter into the prepared baking sheet. Bake for 15-20 minutes, or until the top springs back lightly and edges begin to pull away from the pan.
07 - While the cake bakes, prepare the frosting by melting the butter in a saucepan over low heat. Whisk in cocoa powder, then add milk, vanilla, and powdered sugar until smooth. Stir in chopped pecans.
08 - Pour the frosting over the warm cake and use an offset spatula to spread it evenly to the edges.
09 - Allow the cake to cool until the frosting sets. Slice and serve.
