Chocolate Mug Brownie Ingredients
How to Make a Mug Brownie
- In a coffee mug or other large mug, mix vegetable oil and cocoa powder until you have a thick, chocolatey liquid.
- Add in salt and sugar and thoroughly mix through until smooth.
- Using a fork, thoroughly mix in an egg.
- Carefully stir in flour and baking powder. Thoroughly mix together.
- Fold in chocolate chips until evenly distributed.
- Microwave for 1 minute. The brownie in a mug will rise, then sink a little bit, and should still be wet to the touch.
FAQ
You can make this mug brownie recipe in the oven rather than the microwave. If baking, preheat the oven to 350℉ and bake for about 14 minutes. Make sure to use an oven-proof mug or dish.
You can use a 1:1 substitute of butter instead of oil if you prefer. The flavor will differ and the texture may slightly change.
Tips for Making a Brownie in a Mug
- Don't overcook it: Microwaves vary, start off by cooking for 1 minute, and then cook in 15-second intervals as necessary.
- Picking the right mug: Use a heavy mug, with no metal (this is very important), that can hold at least 1 cup of liquid. This helps when mixing the mug brownie mix to become less messy.
- Let it cool: Letting your mug brownie rest briefly after it comes out of the microwave makes a difference in texture and it's flavor. Serving a mug brownie straight from the microwave will be too hot to enjoy.
