Brownie Mug Cake Tips

  • Use a large mug (at least 14 ounces) so the contents do not spill over during the mixing and baking process.
  • You can use water or milk for the liquid in this recipe. The milk adds slightly more flavor, but either works great.
  • Cook time is calculated for a standard 1200 watt microwave. Cook time may vary depending on wattage. We suggest cooking it for 60 seconds, then check for doneness before cooking for another 30 seconds.
  • Let the brownie cool in the microwave for 5 minutes before eating. The mug will be hot!
  • If you want to save some or all of the brownie for later, cover and store at room temperature. You can reheat for 10 to 15 seconds before consuming.
  • Ice cream, chocolate syrup and whipped cream are optional garnishes for this dessert.

  1. Thanks for the great recipe! I’m generally very sceptical of “hack” type recipes but this was a very quick and effective recipe and saved me when I had a crazy sweet craving at 1:30am.
    This is also the top result when you search on Pinterest – and I think that plus all the brilliant reviews are testament to how good it is 🙂

  2. Definetly making it tonight. I love the idea of adding sugar and chocolate to each ones taste.
