The Best Brownies (Williams Sonoma Recipe)

Jackie proved herself as a little chef in the kitchen today. She put out a batch of brownies in under an hour. When we were at Wrightsville Beach, she and I had an opportunity to go shop at Williams Sonoma. She bought a pan with her earned allowance:

This afternoon here's what she did:

Brownies
8 Tbs. unsalted butter
4 oz. bittersweet chocolate
1/2 cup all purpose flour
1/4 cup cocoa powder
1/2 tsp. baking powder
1/4 tsp. salt
1 cup sugar
2 eggs
1 tsp. vanilla extract

Preheat oven to 350 degrees and grease pan.
Melt butter and chocolate. In a bowl, whisk together flour, cocoa, baking powder and salt until combined. Set aside. In large bowl whisk together sugar, eggs, and vanilla. Add chocolate mixture and whisk in the flour mixture til combined. Bake until top is shiny and toothpick inserted comes out with only a bit of crumbs attached. About 30-40 minutes. Remove from oven and let cool on rack for at least 30 minutes then invert and cut into 12 yummy brownies.
