Ingredients
  

Microwave mug cookie
  • 3 tbsp all-purpose flour
  • 2 tbsp brown sugar
  • 1 tbsp melted butter
  • 1 tbsp milk
  • 0.25 tsp vanilla extract
  • 0.0625 tsp salt
  • 2 tbsp chocolate chips

Equipment

  • 1 microwave-safe mug

Method
 

Mix the dough in the mug
  1. Add all-purpose flour, brown sugar, melted butter, milk, vanilla extract, and salt to a microwave-safe mug and stir until combined. The mixture should look dry at first before it starts coming together.
  2. Stir until a smooth dough forms, scraping the sides of the mug as needed. Stop as soon as the dough is even with no dry pockets.
  3. Fold in the chocolate chips until they’re evenly distributed. You should see chips throughout the dough rather than clumped in one spot.
Microwave and rest
  1. Microwave on high for 60 seconds, then check the cookie. It should look just set around the edges but still slightly soft in the center.
  2. Microwave on high for an additional 0 to 30 seconds if needed until just set. Watch closely so the top doesn’t dry out or turn rubbery.
  3. Let cool for 1 minute before enjoying. The center will finish setting as it rests.

Notes

For a gooier center, stop the microwave as soon as the cookie is just set; it will continue to firm up during the 1-minute rest. Store leftovers covered in the refrigerator for up to 2 days and reheat in the microwave for 10 to 15 seconds. Freezing is not recommended due to texture changes. For a dairy-light option, use plant-based butter and milk in the same amounts.
