Ingredients:
– 2 egg whites
– 1/2 c sugar (heaping – a little more than 1/2 c is totally fine)
– 1.5 T dark cocoa powder
– 1/4 c vegetable oil
– 1/4 t vanilla
– 1/4 t salt
– 1/4 t baking powder
– 1/2 c flour
– 1/2 cup mini chocolate chips
– a few additional Tablespoons of mini or regular-sized dark chocolate chips
How do I make it?
Preheat oven to 325 with a rack in the middle of the oven. Line a heavy duty 13×18 inch jelly roll pan with a silpat (preferred), or parchment paper.
Whisk the egg whites until foamy (a minute or two). Gradually whisk in the sugar, then whisk in the cocoa powder, oil, and vanilla until smooth. Finally, whisk in the salt and baking powder.
Add the flour and stir until smooth. Stir in the chocolate chips.
Pour the brownie batter onto the lined cookie sheet and spread as thinly as possible using a silicone spatula. Sprinkle a few more chocolate chips on top.
Bake for 20 minutes. Remove the pan from the oven; using a pizza cutter or knife, cut it into pieces, without separating. You can do triangular pieces, long strips, or rectangles or squares. Endless possibilities!
Return the pan to the oven for 5 more minutes.
During these 5 minutes, prepare a glass of milk.
Remove from oven and let cool completely. Once it is cool, break the pieces apart.

If you are using parchment paper, you need to hold it down pretty firmly to make sure it doesn’t slip around while you are spreading the batter – silpats are made for moments like this. You may find it helpful to not mix the chips in to the batter, and instead add them after you spread the batter out – it will spread more smoothly using this method. I think it tastes a little better when they are in the batter as well as on top. But it’s pretty similar – whatever works for you!
