This simple brownie recipe is made in a mug in less than 10 minutes, most of which is cooling time so you don’t burn your mouth. In many ways, this recipe is similar to my mug cake recipes, except that it has more chocolate and no leaving agent or egg yolk. I love desserts made in a mug. They can satisfy your sweet tooth cravings in minutes – no need to mix up a big bowl of something or wait for the oven to work its magic.

Also? Kids with a bit of know-how can easily make these recipes themselves. My 10-year-old will make this brownie or this apple crisp in a mug by himself when he wants a sweet treat on the weekend or after school.

This brownie in a mug recipe makes one large, fluffy brownie with bits of gooey, melted chocolate chips throughout. We like to serve it with a big scoop of vanilla ice cream or a generous dollop of whipped cream. (Or both, why not?)

Tips for Success

While this recipe is super easy, there are a couple of tips I strongly recommend. In fact, I daresay they are essential!

  • Use a large mug. Although this brownie does not rise as much as a mug cake, I still like to use a 15-oz mug to make it. This gives your brownie plenty of room to cook in the microwave and leaves lots of room for adding ice cream right to the mug.
  • Use a microwave safe mug. This almost goes without saying. Almost.
  • Stir well. Make sure you stir the brownie batter well to prevent bits of dry batter from getting stuck along the bottom edges of your mug.
  • Let it cool. It is very important that you give this brownie at least 5 minutes to cool after cooking. Not only will it be VERY HOT but the brownie also needs this time to firm up and finishing cooking.
