This quick and easy brownie in a mug recipe only takes 7 minutes to make and uses pantry staple ingredients. It’s the perfect individual serving of a fudgy brownie to satisfy those chocolate cravings!
Why this recipe works
Making a brownie in a mug is really simple. A little brown sugar, flour, milk, cocoa powder, vegetable oil, and vanilla come together in an 8-ounce mug that’s cooked in the microwave for 2 minutes. And of course, this kind of brownie is just begging for a scoop of ice cream and chocolate chips to top!
We love “in a mug” recipes. You can easily throw together the ingredients, pop them in a mug, and microwave it. In the past we’ve made chocolate mug cake and even muggies, which are scrambled eggs in a mug that make a super quick breakfast! These sort of recipes are perfect for saving time when you’re on the go, or want a little sweet treat late at night and don’t feel like dirtying up a bunch of dishes.

Ingredient Info and Substitution Suggestions
OIL – You can use vegetable oil or any neutral-flavored oil you like. Or you can use unsalted butter, just melt it before mixing together the brownie batter.
CHOCOLATE CHIPS – For extra gooey bits of chocolate, double the amount of chocolate chips and stir half into the batter.
ADDITIONS – For a richer, more deep chocolatey flavor, add 1/8 teaspoon espresso powder. You can’t taste the espresso, it just amplifies the flavor of the chocolate.

- Lightly spray the inside of the mug with cooking spray.
- Add all ingredients except the chocolate chips to a microwave-safe 8-ounce mug, and stir to combine.
- Microwave (uncovered) on high power for 60 seconds. Check it to see if it looks super gooey; if so, microwave in 10 second intervals for up to 20 seconds more. (The top should still look a touch wet in spots when it’s done; it will set as it cools.)
- Let it sit for 2 minutes, then sprinkle on the chocolate chips.
- Serve warm, topped with vanilla ice cream if desired.
Frequently Asked Questions & Expert Tips
This recipe is perfect for an 8-ounce mug, though a 6-ounce mug will also do the trick.
As each microwave is different, the cook time may vary slightly. If your brownie still looks too gooey when the timer is up, continue to cook in 10 second intervals for up to 20 seconds more. The top should still look a touch wet in spots when it’s done. It will continue to set as the brownie cools.
Serving Suggestions
Serve your brownie in a mug with an optional scoop of vanilla ice cream, chocolate drizzle, and chocolate chips. Play around with the toppings by adding some chopped Reese’s peanut butter cups, whipped cream, or fresh fruit. It’s up to you!

I’m notorious in my house for making mug recipes. I’ve tried multiple brownie in a mug recipes and this is BY FAR the best one. It has actual brownie like texture whereas lots of the others taste like chocolate cake or are waxy. Soooo good!!
Marci Schachter says
So decadent for such a quick fix. These brownies are epic.
Angie Hartley says
Hi! How much brown sugar? It seems to be left out of the recipe. Thank you!
Kristen Formaro says
Hi Angie, sorry about that. It’s 3 Tablespoons of light brown sugar. I’ve updated the ingredients to reflect that, thank you!
Amanda Formaro says
Hi Angie. It’s there, right under the cooking spray in the list of ingredients. 3 tablespoons light brown sugar.
Helen Wickstrom says
It shows the 3 tablespoons light brown sugar, but when you print the recipe it is not there.
Amanda Formaro says
I just clicked on the print button and I see the brown sugar. Are you using the button? I’m not sure why it’s not showing for you.
