Ingredients
  

  • 4 tablespoons all-purpose flour
  • 2 tablespoons granulated sugar
  • ¼ teaspoon baking powder
  • Pinch of salt
  • 3 tablespoons milk any kind works
  • 2 tablespoons vegetable oil or melted butter
  • ¼ teaspoon vanilla extract
  • 2 tablespoons chocolate chips semi-sweet or milk chocolate
  • 1 tablespoon additional chocolate chips for topping optional

Instructions
 

  • Prepare your mug by lightly greasing the inside with butter or cooking spray to ensure easy cleanup (though this is optional).
  • Combine the dry ingredients by adding the flour, sugar, baking powder, and salt to your mug. Stir with a fork until well mixed.
  • Add the wet ingredients – pour in the milk, oil or melted butter, and vanilla extract. Mix thoroughly until no lumps remain, making sure to scrape the bottom of the mug where flour often hides.
  • Fold in the chocolate chips gently with your fork, distributing them evenly throughout the batter.
  • Sprinkle the additional tablespoon of chocolate chips on top if using (this creates a delicious melty top layer).
  • Microwave on high for 60-90 seconds. Start with 60 seconds for a gooier center, and add additional 10-second intervals if needed. The cake is done when it rises and the top looks set but still slightly moist.
  • Let stand for 2 minutes before eating – this allows the cake to finish cooking and prevents burning your mouth on molten chocolate chips.

Notes

  • For the best texture, avoid overmixing the batter which can make your cake tough.
  • The cooking time varies depending on your microwave’s wattage – start with less time as you can always add more.
  • For a richer version, use melted butter instead of oil and add an extra tablespoon of chocolate chips.
  • Different mugs conduct heat differently – wider mugs typically cook faster than taller, narrower ones.
  • This recipe doubles easily if you’re using an oversized mug or want to share, but you’ll need to increase the cooking time by about 30 seconds.
