  1. In a mixing bowl, sift together the flour, salt, and baking soda.  Stir in the sugar.
  2. In a small saucepan, simmer the butter, cocoa, instant coffee, and water.  When it’s all melted, turn off the heat.
  3. Add this to the dry ingredients.  In a small mixing bowl, beat the eggs, sour cream and vanilla until completely combined.  Add this to the cocoa mixture.
  4. Pour into a buttered 15x10x1 baking sheet or casserole dish.
  5. Bake for 20-25 minutes at 375 degrees.
  6. For the ICING: Bring butter, cocoa, milk, and instant coffee to a boil.  Remove from heat, and add sugar, vanilla and salt.  Mix well and spread over the cake when it comes out of the oven.  Sprinkle with toasted pecans.


I made this into a layer cake by putting it into cake pans and made a quick cream cheese frosting for the middle.  If you want to do this whip together 1 (8 ounce) block of cream cheese with 1 cup powdered sugar, 1/2 teaspoon salt, and 2 teaspoons vanilla.
