I was tempted to call this recipe “One-Minute Microwave Brownie For One,” but if you have some restraint and self-control you can split it with someone and it becomes For Two.  I make this mug brownie for my daughter and I when a craving for chocolate in the baked and gooey form comes over us and handfuls of chocolate chips or nibbles of chocolate bars from the pantry just won’t do. There’s something about warm, molten chocolate that is just so satisfying, and when you need your chocolate fix in this fashion and have no patience to wait, this microwave brownie is the recipe to make.  It’s extremely easy, made in one small bowl without a mixer, and your brownie is ready in one minute, give or take, depending on your microwave’s strength. This microwave chocolate brownie in a mug is egg-free. That’s great for those of us who like our brownies more along the lines of raw and gooey rather than well cooked. There’s no baking powder or baking soda in this easy mug brownie recipe, which is great for a few reasons. The texture stays denser and more brownie-like rather than cakey.  And if you’ve ever ‘baked’ anything in the microwave, you know that things have a tendency to rise and overflow with no warning. That’s less likely to happen with this recipe sans baking powder or soda. The texture isn’t as densely chewy as typical baked brownies, but ‘beggars can’t be choosers’ is what comes to mind with this recipe. It’s a mug brownie ready in one minute, it’s warm, decadent, and studded with chocolate chips throughout. Enough said.
