Best Brownie Recipe

This is the only brownie recipe you'll ever need for the rest of your life.

Be prepared for the consequences of baking these:

You'll be the most popular person at the party.
You'll never be able to eat a brownie made from a box mix again, even if it's Ghirardelli.
You'll instantly gain 10 pounds.
Your children will rise up and call you blessed, and your husband also will praise you.

This recipe comes from the America's Test Kitchen cookbook, over which I have sung praises time and time again.  BUT, there is also a little twist of my own involved.

5 ounces bittersweet chocolate chips
2 ounces unsweetened baking chocolate
1 stick butter
3 TBS Dutch processed cocoa powder
1 1/4 cups sugar
3 large eggs
2 tsp. vanilla extract
1/2 tsp salt
1 cup all purpose flour

Heat oven to 350 degrees.  Line an 8 inch square pan with foil, then spray it with non-stick baking spray.  Toss all the kinds of chocolate, cocoa powder, and butter in a microwave safe bowl and heat until melted.  Stir together.  Let mixture cool slightly.  In another bowl, whisk together eggs, sugar, vanilla, and salt until combined, about 15 seconds.  Add chocolate mixture in and stir until combined.  Last, stir in the flour until no streaks remain.  Scrape batter into prepared pan and smooth the top.  Bake until toothpick comes out clean, about 35-40 minutes.  Let cool to room temperature on a wire rack, about 2 hours.  (Can be shortened if you are ravenous or addicted to chocolate.)  Pull the brownies from the pan using the foil, then cut into small (hahahahaha...who do they think we are?) squares.

I'm sure this recipe, as given, is fabulous.  BUT, what about my top secret twist?

I am so enterprising (out of cocoa powder) that I decided (desperately as a last measure) to put in a packet of Starbucks hot chocolate mix instead of the cocoa powder the recipe called for.  And the results were....

AMAZING.

Now I make it that way every time, at least until my box of hot chocolate runs out.  These are seriously good brownies.  I have a pan of them cooking in the oven right now.  Let me know if you make them and what you think.
