Crush the Oreos: Place the Oreo cookies in a microwave-safe mug and crush them using a spoon or fork until they’re fine crumbs.
Add Milk:Pour the milk into the mug and mix until the Oreos form a smooth batter.
Combine Ingredients:Add the sugar (if using), baking powder, and all-purpose flour to the mug. Mix well to create a uniform batter.
Microwave:Microwave the mug on high for 1-2 minutes, depending on the power of your microwave. Check after 1 minute to avoid overcooking.
Cool & Serve:Let the mug cake cool for about a minute before enjoying. Optionally, top with whipped cream, ice cream, or crushed Oreos for extra flair.
Notes
Cooking times may vary based on your microwave’s wattage. Always keep an eye on the mug cake as it cooks.
