# Expert Suggestions:

01 -
  • It actually delivers fudgy chocolate richness in less time than your coffee brews.
  • No fancy equipment, no baking sheet drama—just a mug and a fork.
  • When a craving hits at 10 p.m. and your willpower is gone, this saves you.
02 -
  • The mug size matters more than you'd think—too small and it overflows, too large and it cooks unevenly.
  • Overcooking by even 15 seconds turns fudgy into cake, which defeats the entire point.
  • Cold milk makes a lumpier batter, so room-temperature ingredients actually help here.
03 -
  • Keep your cocoa powder fresh—old cocoa loses its punch, and this recipe relies on chocolate flavor more than anything else.
  • Use a ceramic or glass mug, not plastic—plastic can leach weird flavors and doesn't distribute heat as evenly.
  • If your microwave runs hot, start checking at 45 seconds rather than waiting the full minute.
