# How to Make It:
01 - Place Oreo cookies in a microwave-safe mug and crush thoroughly using a fork until finely crumbled.
02 - Pour in milk and mix until cookies are fully soaked and thick paste forms.
03 - Stir in flour, optional sugar, and baking powder until well blended.
04 - Add egg and optional vanilla extract; mix until batter is smooth and uniform.
05 - Microwave on high for 1 minute and 30 seconds. Check doneness; cake should be set but moist. If needed, cook additional 10–20 seconds.
06 - Allow to cool for 1–2 minutes before enjoying directly from the mug.
