Instructions
For the brownie: Melt chocolate squares, butter & ¾ cup chocolate chips in a saucepan over medium-low heat. Cool 5 minutes. Sift flour, baking powder & salt into a bowl.
In a large bowl, whisk eggs, sugar & vanilla. Add slightly cooled, melted chocolate mixture. Add dry ingredients until incorporated. Fold in extra ½ cup chocolate chips.
Pour batter into a greased 13x9 inch pan & bake at 350*F for 25-30 minutes.
After brownies have cooled completely, make the Whipped Chocolate Frosting: In a stand mixer with the whisk attachment, whisk all the ingredients until stiff peaks. Spread over cooled brownies. (This layer may lose some of it's volume over time.)
For the Ganache Drizzle: Heat ingredients in the microwave for 10 to 15 seconds. Stir until smooth. Drizzle over frosting. Refrigerate until solid. (*If doubling or tripling the ganache for an extra layer of frosting: Heat ingredients in short 10-15 second bursts in the microwave until melted, stirring in between bursts; do not burn chocolate. Allow to cool slightly & then spread over frosting & refrigerate until solid.)
