Microwave Chocolate Mug Brownie

Total Time
Prep 1 min
Cook 1 min

This makes a delicious brownie for one in about a minute. I used a 1500 watt microwave. 60 seconds makes a molten center brownie. 75 seconds make a uniformly done brownie. Careful not to overcook.

This is 5 stars with these corrections: switch the water out for milk and decrease the sugar & flour to 2T each instead of 4T.

I'm leaving this review for the people who, like me, have searched through multiple brownie-in-a-mug recipes that ended up tasting like total dirt to find a good one. I have tried a handful of recipes that had good reviews and when they end up tasting like crap even though I followed the directions exactly, I wonder where I went wrong. This is FINALLY a decent recipe that actually tastes like a brownie and doesn't end up dry and bitter (but that can happen to any recipe if you microwave it too long, be wary). I think one of the secrets is to use melted butter instead of oil. It is essential to the way it cooks but doesn't give it an oily taste. If you don't like it to be too sweet, cut the sugar by a tablespoon or two. I also substituted milk for water, which I suggest doing in any cake/pancake/muffin recipe. I cooked it in a 1500 watt microwave for 60 seconds and it was just a bit too liquidy/molten for me so I gave it another 15 seconds and it was great. My end conclusion is that you're honestly just not going to be able to make a perfect tasting brownie like you would by baking a box mix in an oven for an hour by just throwing 5 or 6 ingredients in a mug and microwaving it for a minute, but that when you are craving a chocolate fix and want a decent brownie this recipe will definitely satisfy you! I really hope my review helps someone!

Yum!! I tried it by the recipe first, then made some alterations... I used self raising flour instead of plain. Also, I halved the sugar to 2Tbs but I used 1Tbs white sugar, 1Tbs brown sugar which made it nice & fudgy :-) Cooked for 60sec in 1200w microwave :-)
