Ingredients Method Notes

Ingredients
  

  • 1 tablespoon  unsalted butter
  • 1 tablespoon  brown sugar
  • 1 tablespoon  granulated sugar
  • ⅛ teaspoon  vanilla extract
  • Pinch of salt
  • 1 egg  yolk (no white)
  • 3 tablespoons  all-purpose flour
  • 2 tablespoons  chocolate chips (or chunks)
  • Splash of milk (optional, if the batter looks dry)

Method
 

  1. Place the butter in your favorite microwave-safe mug and heat for about 20–25 seconds.
  2. Add both sugars, vanilla, and a tiny pinch of salt. Stir until everything is combined.
  3. Crack an egg and separate the yolk — you’ll only need that rich, golden part. Add it to the mug and stir well until fully blended.
  4. Stir in the flour with a fork or spoon until no streaks remain. 
  5.  Fold in the chocolate chips — or whatever mix-ins you love.
  6. Place the mug in the microwave and cook for 40–60 seconds, depending on your microwave’s power. Start with 45 seconds and check the texture — it should look just set on top but still soft in the middle.

Notes

  • Use a standard-size mug (10–12 oz) so the batter doesn’t overflow.
  • Don’t overmix — stir just until combined to keep the texture soft.
  • Microwave in short bursts if unsure; it’s better slightly underdone than overbaked.
  • Eat it warm. Like cookies fresh from the oven, it’s best enjoyed right away.
