No need to fire up the oven—this brownie in a mug recipe delivers all the fudgy, chocolaty goodness you crave, all in one little mug!
When summer is in full swing or the holidays roll around, and the house is buzzing with kids, friends, and all the wonderful chaos they bring, I’m all about baking big batches of sweets. But once the kids are back at school and it’s just Michael, the pups, and me, I definitely don’t need a whole tray of my favorite brownie recipe tempting me every time I walk through the kitchen! My go-to for those sudden chocolate cravings? A brownie in a mug—the perfect dose of gooey, chocolaty goodness for one. Plus, clean-up couldn’t be simpler, with just one mug to wash.
While the brownie is delicious on its own, you can never go wrong with a dollop of whipped cream or a scoop of vanilla ice cream. And if you’re in the mood to truly gild the lily, sprinkle some chocolate chips on top midway through cooking.
“This is by far the best brownie in a mug recipe I’ve made. And I’ve made a lot.”
What You’ll Need To Make A Brownie In A Mug
Step-by-Step Instructions
Put the butter and chocolate chips in a mug—an 8-ounce mug is ideal, but a bigger one works too. Microwave in 20-second bursts, stirring in between, until the chocolate is mostly melted, about 40 seconds total.
Using a small spoon, stir the mixture until the chocolate is melted and completely smooth.
Stir in the sugar, vanilla, and salt.
Add the egg yolk and stir until smooth.
Add the flour to the mug and stir to combine.
Stop stirring when the batter is smooth and shiny. Using a paper towel, wipe down the batter on the inside edges of the mug.
Microwave uncovered on high for 45 to 55 seconds, until the brownie is puffed and set. (If your microwave runs hotter or cooler, you may need to adjust the time.) Let it rest for 5 minutes, then dig in straight from the mug—preferably with a scoop of vanilla ice cream or a dollop of whipped cream.

- ⅛ teaspoon vanilla extract
- Pinch salt
- 1 egg yolk
- 3 tablespoons all-purpose flour
Vanilla ice cream or whipped cream, for serving (optional)
Instructions
- Place the butter and chocolate chips in a mug (an 8-ounce mug is the perfect size, but larger will work too) and melt in 20-second increments in the microwave, on high power, stirring in between, until the chocolate is mostly melted, about 40 seconds total. Using a small spoon, stir until completely smooth. Stir in the sugar, vanilla, and salt. Add the egg yolk and stir until smooth. Stir in the flour until smooth and shiny. Using a paper towel, wipe down the batter on the inside edges of the mug.
- Microwave, uncovered, on high power for 45 to 55 seconds until puffed and set. (You may need to adjust the time for less or more powerful microwaves.)
- Let the brownie rest for 5 minutes. Serve in the mug with a scoop of vanilla ice cream or a dollop of whipped cream.
- Note: If you'd like melty chocolate chips on top, as shown in the photo, microwave the mixture for 30 seconds, sprinkle on some chips, then finish cooking for 15 to 25 seconds more.

I made this last evening, and we both enjoyed it, although it was a bit too sweet for my tastes. I found it took a bit more than the noted time to cook the brownie, and I stopped it when it was still sort of brownie-pudding consistency. I think that was at about 1 min & 15 seconds (our microwave works in 15 second increments).
I may try to make again cutting the sugar, and see if I enjoy it more.
It was easy to make.
