Ingredients
  

  • 6 Oreo cookies original
  • 3 tablespoons whole milk or oat/almond milk for dairy-free
  • ¼ teaspoon baking powder

Equipment

  • 12 oz microwave-safe mug
  • Fork or spoon for crushing/mixing

Method
 

  1. Place 6 Oreo cookies into a 12 oz microwave-safe mug.
  2. Use a fork to crush the Oreos into fine crumbs — the finer, the better.
  3. Add 3 tablespoons of milk and ¼ teaspoon baking powder.
  4. Stir until fully combined into a thick, smooth batter.
  5. Microwave on high for 60–90 seconds. Start at 60 seconds and check — the top should look set but slightly moist.
  6. Let cool for 30 seconds (mug will be hot!). Add desired toppings and serve immediately.

Notes

  • For a 2-ingredient version, skip the baking powder. The cake will be denser but still delicious.
  • For dairy-free/vegan: substitute oat milk, almond milk, or soy milk.
  • Don't overcook — a slightly underdone center firms up as it cools and stays wonderfully gooey.
  • Use a mug that's at least 12 oz to prevent overflow.
  • Flavor variations: try Mint Oreos, Golden Oreos, or Double Stuf for different flavors.
