Preheat the oven to 300°. Prepare a 12x17-inch baking sheet by lining with silicone mat or parchment paper.
In the bowl of your mixer, beat the egg whites on medium speed until foamy, about 1 minute. With the mixer running, gradually add the sugar, 1 tablespoon at a time. Continue to beat on medium speed until thickened, about 2 minutes.
In a separate bowl, combine the flour, cocoa powder, salt, and baking powder, stir with a whisk to combine.
Add the flour mixture, butter, and vanilla to the egg white mixture and mix on low speed just until combined.
Turn the batter out onto the prepared baking sheet. Using an offset spatula, spread the batter very thin, about ¼-inch thick, leaving about 1 inch border around the edge of the pan.
Sprinkle chocolate chips evenly on top.
Bake for 30 minutes. Remove from the oven, cut into 2-inch squares. Place back in the oven for 10 minutes. Turn off the oven and without opening the oven door, let the brownie brittle cool in the oven until completely cool, at least 1 hour.
Remove brownie brittle from the oven and break apart. Place pieces on a cooling rack.
Warm melting chocolate according to package instructions. Using a spoon, drizzle over brownie brittle and let sit until chocolate is completely set. Store in an airtight container.
Recipe Note
In addition to its rich dark chocolate taste, black cocoa is often used to achieve a deep, dark chocolate color. If you'd like a darker brownie brittle for more of a "cookies and cream" taste and appearance, feel free to add additional cocoa powder!
