How to make a brownie in a mug

Once you have your ingredients, you can make your brownie in a mug in less than 5 minutes! Make sure you use a microwave-safe mug before mixing your ingredients.

  • First, whisk dry ingredients. Whisk together the flour, sugar, cocoa powder and salt.

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.

    Great easy recipe!! So quick and so good!  It Literally only took 90 seconds in the microwave.  It’s a large serving too so you can share or eat it yourself. I made 1 in a bowl and 1 in a mug. Both were perfect.  My husband and I liked it more than traditional boxed brownies.  It was a little sweet for my daughter (who ever heard of such a thing:) so I may leave out a few chocolate chips for her.  Thanks for this quick last minute dessert recipe, when you just really need some chocolate!

    Made this with coconut oil and almond milk and some dark choc chunks.  Was delicious!  Great pick me up after a long day with a cranky teething baby, and something I actually had the energy to make.
