    This recipe for microwave mug brownie has been a favorite of mine for a while. Last year I shared a video of me making it on Instagram and it is the most saved post on my feed. I heard from so many people that it is the most delicious gooey brownie in a mug.

    Be sure to give a try and save it for later when you need to treat yo self in the future.

    Is it safe to cook a brownie in the microwave?

    Yes, this recipe is safe. The egg is blended with the other ingredients and will cook thoroughly in the microwave. It is fine to cook this single brownie in a microwave-safe mug or bowl. Keep in mind that microwaves can vary, so it is best to cook the mug brownie for 1 minute and then in 10-second increments until done. The brownie is done when it has slightly risen, is not raw in the center, but still gooey.

    Can you overcook a brownie in a mug with egg?

    Yes, you can. You will know the brownie has been overcooked if it is completely dry and tough. The best way to avoid this from happening is by cooking for 1 minute before checking. Then cook for 10 seconds at a time checking each time until done.

      Thank you for those! I finally found a brownie mug recipe that I actually liked. I actually enjoyed this one and ate the entire thing, unfortunately all of the other ones ended up in the trash. I substituted cocoa powder for brownie mix, but kept everything else the same including measurements. This was delicious, thank you again!

      This is my go-to mug brownie recipe! It's easy and simple and that's what I want in a quick recipe. I've looked at others that call for sifting flour and cocoa powder and have seven or eight ingredients and multiple steps and teaspoons and half tablespoons... Nah. This is easy and I love that it's just a mug, a tablespoon, and a spoon to mix!

      I do reduce the sugar to 1 tablespoon but that's entirely so I can pour tooth-achingly-sweet caramel sauce on top and I like a less sweet base to offset that.

      I make this brownie mug recipe one night and save the second half for the next night and it reheats wonderfully the next day.

      I've learned from experience that I never like mug cakes with egg - they come out too cake-y for me, and sometimes even tasting like egg. So I substituted with flax egg this time. The flavor of the brownie was perfect! Texture was great too, but also a bit too oily.... I would rate it 4/5, but because I used the flax egg I don't know how much they will have messed with things so I don't want to give it a REAL rating. 🙂
      But thank you for the yummy treat!
