Equipment

  • Microwave-safe mug (10–12 oz)
  • Fork or spoon (for mixing)
  • Microwave

Ingredients
  

  • 4 Oreo cookies
  • 3 tablespoons milk any type
  • ¼ teaspoon baking powder optional, for extra fluffiness
  • 1 teaspoon sugar optional, for extra sweetness

Instructions
 

  • Crush the Oreos – Place the Oreo cookies in a microwave-safe mug and crush them using a fork or spoon until they become fine crumbs.
  • Add the milk – Pour in the milk and stir until the mixture is smooth and well combined.
  • Optional additions – Stir in baking powder for a fluffier texture and sugar if you prefer it sweeter.
  • Microwave – Heat the mixture in the microwave on high for 60–90 seconds until the cake rises and sets. Cooking time may vary depending on your microwave’s power.
  • Check doneness – Insert a toothpick or fork into the center. If it comes out clean or with a few moist crumbs, the cake is ready.
  • Let it cool – Allow the mug cake to cool for 1–2 minutes before enjoying.
  • Enjoy! – Optionally, top with whipped cream, ice cream, or extra crushed Oreos for an indulgent touch.

Notes

Adjust the sweetness – Oreos are already sweet, so adding sugar is optional.
Baking powder tip – If you prefer a slightly fluffier mug cake, add ¼ teaspoon baking powder.
Microwave variations – Every microwave is different, so adjust cooking time as needed. Start with 60 seconds and add 10-second intervals if needed.
Dairy-free option – Use almond milk, oat milk, or soy milk for a dairy-free version.
