1/2 cup semisweet chocolate chips
4 ounce semisweet chocolate baking bar
1/2 cup unsalted butter (1 stick)
1 cup firmly packed brown sugar
1 tsp vanilla extract
2 large eggs
3/4 cup plus 2 tbs all-purpose flour
1/4 tsp baking powder
1/4 tsp salt
Preheat oven to 350 degrees. Line an 8x8 baking pan with parchment paper. Chop the 4 ounce baking bar into small pieces and melt in a heatproof bowl over simmering water. Add the butter and stir until smooth. Remove from heat and let cool until it reaches room temp. Once cooled, stir in the brown sugar and vanilla. Add eggs and mix well. In a separate bowl shift together the flour, baking powder, and salt. Fold in the dry ingredient mixture to the chocolate mixture and mix until blended. Stir in chocolate chips and pour batter into pan. Bake for 25-30 mins and remove from oven to cool for 10 mins.
