Cappuccino Brownies

Yum...  Just thinking about these is making my mouth water.  I don't remember where I got this recipe, but my guess would be Martha Stewart.

1/2 c unsalted butter, softened
4 oz unsweetened chocolate, coarsely chopped
1 1/2 c sugar
1 tbls instant espresso powder
2 tsp vanilla
4 large eggs, lightly beaten
1 c flour
3/4 tsp cinnamon
1/2 tsp nutmeg
1/4 tsp salt
3/4 c semi-sweet chocolate chips

1. Preheat oven to 325 degrees with rack in center.  Butter a 9-in. square baking pan.  Line bottom with parchment paper.  Coat paper with butter.  Set aside.
2. In a large heatproof bowl, combine butter and unsweetened chocolate.  Place over a saucepan of simmering water, stirring occasionally until completely melted.  Let cool slightly.  Whisk in sugar, espresso powder, vanilla and eggs.
3. In a small bowl, whisk together flour, cinnamon, nutmeg and salt.  Add to chocolate mixture and stir until just combined.  DO NOT OVERMIX!  Fold in chocolate chips.
4. Pour into pan and bake until a toothpick comes out slightly wet - about 30-35 minutes.  Cool in pan on wire rack until completely cool.  Remove from pan.  Using a damp, warm knife, cut into squares.  Remove parchment paper and serve.
