Chocolate Toffee Sheet Cake

sorry horrible picture my flash went crazy on the cake :)

2 cups flour
2 cups sugar
1/4 teaspoon salt
1/4 cup (heaping) cocoa powder
2 sticks salted butter
1 cup boiling water
1/2 cup buttermilk
2 eggs, beaten
1 teaspoon baking soda
1 teaspoon vanilla extract

For the Icing:
1 3/4 stick Butter
1/4 cup (heaping) cocoa powder
7 Tablespoons Milk
1 teaspoon vanilla extract
3 1/2-4 cups Powdered Sugar
1/2 cup finely chopped pecans (optional)
2/3 cup toffee bits

Directions:

For the Cake:
Preheat oven to 350ºF. Spray a sheet cake pan with non-stick cooking spray (or Bakers Joy). In a large bowl, mix together the flour, sugar, and salt. Next, in a medium saucepan, melt the butter over medium-high heat. Add the cocoa powder and whisk together. Once combined, add hot coffee & allow mixture to boil for 30 seconds. Remove from heat and pour over flour mixture and stir it in to cool down the mixture.
In a measuring cup, whisk together the buttermilk, beaten eggs, baking soda, and vanilla extract. Pour buttermilk mixture into butter/chocolate mixture and whisk until well combined. Pour batter into the prepared sheet cake pan and bake at 350ºF for 20 minutes.

For the Icing:
While cake is in the oven, it's time to make the icing. Melt butter in a medium saucepan over medium high heat. Add the cocoa powder and whisk to combine. Turn off heat and add the milk, vanilla, and powdered sugar; stir together until well combined. Next add the chopped pecans and toffee bits, stir together, and pour icing over warm cake (spreading it lightly with a spatula).

I got this recipe from mylifeasamrs It was super yummy and it was gone fast at the party. I think that the only thing that I would change is to add more toffee chips to the frosting.
