    microwaving mug brownie recipe



  • Don't overcook it: Microwaves vary, start off by cooking for 1 minute, and then cook in 15-second intervals as necessary.
  • Picking the right mug: Use a heavy mug, with no metal, that can hold at least 1 cup of liquid. This helps when mixing the mug brownie mix to become less messy.
  • Let it cool: Letting your mug brownie rest briefly after it comes out of the microwave makes a difference in texture and it's flavor. Serving a mug brownie straight from the microwave will be too hot to enjoy.
