Step 1

Combine all ingredients except chocolate chips into an oversized mug and mix with a small whisk until batter is smooth. Stir in half of the chocolate chips.

Step 2

Line a large round plate with parchment paper. Dump cookie batter onto plate. Batter will be quite sticky. Try your best to shape it into a round disc (like photo above). Add remaining chocolate chips on the surface.

Step 3

Cook in microwave for about 50 seconds (careful not to overcook because just a few seconds can overcook the cookie). Let cookie cool for a few minutes before eating.
