Tips and Variations

2. Go Fudgier: For rich, fudgy brownies, use milk or a plant-based milk alternative in place of water.

Frequently Asked Questions

Why is my mug brownie so dry and cake-like?

A dry, cakey mug brownie is typically the result of overcooking. Microwaves work fast, and even a 15-second difference can produce a different texture. Next time, cook for less time, and leave a chocolate toothpick inserted partway so you can check after 25 minutes.

Can I substitute butter for vegetable oil?

Yes, you can! Butter also melts nicely in place of vegetable oil. That little extra bit of butter is going to add just a little richness, a little butteriness, to your brownie. But make sure to use the equal (2 tablespoons) of melted butter.

My mug brownie overflowed. What did I do wrong?

That’s likely to be because either your mug isn’t big enough or you’ve stirred for too long and the batter contains too much air. Be sure to use a regular-sized coffee mug, no smaller than 8-10 ounces, and don’t overmix the ingredients.

What type of cocoa powder is best?

This recipe is fine with either natural unsweetened cocoa powder or Dutch-processed cocoa powder. Natural cocoa powder will provide the brownie a less-heavy, fruitier chocolatey taste) and Dagoba cacao powder because the brownie will have a deeper, mellower chocolate taste. or simply as an excuse for a midnight snack!
