Special equipment: a 26-by-18-by-1-inch baking sheet
Preheat the oven to 350 degrees F. Spray a 26-by-18-by-1-inch baking sheet with nonstick spray and line with parchment paper, leaving a 1-inch overhang over the sides. Spray the parchment with nonstick spray.
In a large bowl, whisk to combine the flour, cocoa powder, baking powder and salt; set aside.
In a stand mixer, beat the butter and sugars together on medium-high speed until light and fluffy, about 3 minutes. Reduce the speed to low and beat in the eggs 1 at a time, then the vanilla extract until completely incorporated. Add the flour mixture a cup at a time and beat until combined.
Remove the bowl from the stand and use a rubber spatula to fold in the chocolate chips and cherries. Press the dough evenly into the prepared pan and bake until cooked through, about 30 minutes. Cool on a rack to room temperature, about 20 minutes.
Pour the Chocolate Ganache over the brownies and let cool. Cut into 32 rectangle-shaped cookie bars.
Put the chocolate chips in a medium bowl and set aside. In a small saucepan, heat the heavy cream over medium heat until small bubbles form around the edge of the pan, about 3 minutes. Pour the heavy cream over the chocolate and stir until completely melted and smooth.
