Line a cookie sheet with a silphat mat or parchment paper.

In a bowl whisk the egg whites until foamy

Add in sugar and then cocoa powder, oil and vanilla until smooth.

Add in salt, baking powder and powdered milk

Add the flour and stir until smooth.

Add in 1/2 C chocolate chips

Pour batter onto lined cookie sheet and spread as thinly as possible with back of spoon.

Sprinkle with a few more chocolate chips to fill in the holes and then sprinkle with toffee bits.

Bake in a 325 oven for 20 minutes.

Remove from oven and use a pizza cutter to cut into "shrad" shaped pieces.

Return to oven for 5 more minutes.

Remove form oven and cool. Break into pieces.

If any of the pieces are too thick and chewy you can return them to the oven at 250 degrees for 20 more minutes and then re-cool.

If your batter is thin enough though you shouldn't have a problem.
