Mug Brownie

  • Jump to Recipe
  • A few years back, and still today, my edible cookie dough remains one of my most popular recipes. I put making a brownie in a mug on my to-do list and four years later I am just getting around to making it.

    I like a fudgy brownie (versus cake-like) so expect a little gooiness here. It is a cross between a cooked brownie and brownie batter. Pure deliciousness.

    The challenge here is that the mixture is cooked and to get the right texture, but not too dry and not too fudgy, you still can’t really use an egg. One yolk or white and it is still too much.

    I really took one for the team recipe testing and tasting over 5 mug brownie recipes. Yes, 5.

    Some didn’t make enough, others left you wanting more, I didn’t like having to mix the dry ingredients, melt butter in another and then mix. I just wanted to basically have a dump cake in a coffee mug.

    The Mug

    Don’t use a standard coffee mug. You’ll want something oversized around 14 or 16 ounce should work.

    Also note that that they get super hot in the microwave. Be mindful that if it has metallics on it, it could spark or get even hotter. Stay away from those.

    Cooking Times

    Cooking times are going to vary. I know I’ll get a billion comments about how theirs didn’t cook right so I am going to talk about this issue here and also in the recipe notes.

    You can two variables (three if you count altitude): the wattage of your microwave and the shape of your mug. A higher wattage will cook faster. A squattier, wide mug will cook faster.

    I recommend testing the time in 15 second increments until you find your sweet spot.

    Add Ins

    You had no idea there were so many things to consider when making a mug brownie, did you? Now to the fun stuff…

    What to mix in! Here are some of my favorite toppings and mix ins. Keep in mind that some of the candies might also require a little longer cook time (only by 15 seconds or so), but they are still quick and easy.
