Is A Brownie In A Mug As Good As A Regular Brownie?
Yes, a Brownie in a Mug is every chocolate lover's dream come true. It's warm, gooey, and rich in flavor, with the perfect fudgy texture you expect from a traditional brownie.
The best part? You only need one mug, a microwave, and a few basic ingredients to make it. No need for fancy equipment or long baking times!
Ingredients You'll Need
- ¼ cup All-Purpose Flour- Provides the structure and body of the brownie, helping it hold its shape while still staying soft.
- 2 tablespoon Cocoa Powder- The main source of chocolate flavor, giving the brownie its rich, fudgy taste.
- 2 tablespoon Sugar- Sweetens the brownie and balances the bitterness of the cocoa.
- ¼ teaspoon Baking Powder- Acts as a leavening agent, giving the brownie a little lift so it isn't too dense.
- Pinch of Salt- Enhances the flavors, especially the chocolate, and balances the sweetness.
- ¼ cup Milk- Provides moisture to the batter, ensuring the brownie isn't dry.
- 2 tablespoon Vegetable Oil- Adds richness and keeps the brownie moist and tender. Unlike butter, it creates a softer crumb.
- ¼ teaspoon Vanilla Extract- Adds warmth and depth of flavor, complementing the cocoa and sugar.
How To Make A Brownie In A Mug
Mix the Dry Ingredients. In a 16 ounce microwave-safe mug, whisk together ¼ cup flour, 2 tablespoon cocoa powder, 2 tablespoon sugar, ¼ teaspoon baking powder, and a pinch of salt.
Add Wet Ingredients. Stir in ¼ cup milk, 2 tablespoon vegetable oil, and ¼ teaspoon vanilla extract until smooth. Be sure to mix all the ingredients thoroughly, scraping the bottom and sides of the mug until no dry streaks remain.
Microwave. Place the mug in the microwave and cook on high for 1 minute to 1 minute 15 seconds in 30 second bursts. This prevents it from becoming overcooked and dry. The brownie should rise and be set on top but still moist in the center.
Add Toppings. Allow the mug brownie to rest for 1 minute for the heat from the mug to finish dispersing. For an extra treat, sprinkle chocolate chips on top or add a scoop of vanilla ice cream. Enjoy your brownie straight out of the mug while it's still warm!
Tips And Tricks
Making a Brownie in a Mug is super simple, but a few tricks can help you get the best results in under 30 minutes every time:
- Don't overcook. Microwave times vary, so start with 1 minute and check the brownie.
- Mix thoroughly. Be sure to mix the batter well to avoid any pockets of dry ingredients.
- Use a large mug. Make sure your mug is big enough (at least 12 oz) to prevent the batter from overflowing as it rises.
Variations
If you want to switch things up, here are a few fun and delicious variations you can try to one of our best brownie recipes:
- Peanut Butter Brownies- Swirl a spoonful of peanut butter into the batter before microwaving for a nutty twist.
- Mint Brownies- Add a drop of peppermint extract and some crushed peppermint candies for a refreshing, minty flavor.
- Brownie Ice Cream- Break the mug brownie into chunks and mix it into your favorite ice cream!
- S'mores Brownie- Top with mini marshmallows and graham cracker crumbs after microwaving for a gooey, campfire-inspired treat.
What To Enjoy With A Brownie In A Mug
While this Brownie in a Mug is delicious on its own, you can take it to the next level by pairing it with:
- Vanilla Ice Cream- The warm brownie and cold ice cream combination is irresistible!
- Whipped Cream- Add a dollop for an extra creamy finish.
- Fresh Berries- A handful of strawberries or raspberries adds a fresh, fruity contrast to the rich brownie.
How Long Do They Last?
A mug brownie has its best texture immediately after its one-minute rest. If necessary, cover the cooled mug and keep it at room temperature for up to one day. Reheat it for only a few tested seconds because additional microwave time can make it rubbery. Freezing is not recommended unless testing confirms that the texture recovers successfully.
However, it's so quick to make that we recommend whipping up a fresh one each time you crave a brownie!
Frequently Asked Questions
For the best mug size for a brownie in a mug, use a microwave-safe 12-16 oz mug. It gives enough headspace to prevent a mug brownie overflow while still cooking evenly into a fudgy mug brownie with a gooey center.
Avoid small 8-10 oz mugs because the batter can rise quickly and spill, especially with baking powder or vigorous mixing.
As a rule, don't fill the mug more than halfway, and if your microwave runs hot, cook in 30-second bursts so the edges don't overcook while the center sets.
A mug brownie turns rubbery almost always because it's overcooked. Microwaves cook fast, and even an extra 10-15 seconds can push a microwave brownie in a mug from fudgy to chewy and tough (plus it keeps cooking from residual heat).
It can also happen if you used a too-small mug (causing uneven cooking), overmixed the batter, or added too much flour relative to moisture.
A brownie in a mug usually turns dry because it's overcooked (microwave wattage varies a lot), or because the batter has too many dry ingredients.
Using a smaller mug can also make a microwave mug brownie cook unevenly, so the edges dry out before the center sets.
For a more fudgy mug brownie, use a 12-16 oz microwave-safe mug, measure dry ingredients carefully, add a splash more milk or a teaspoon of oil if the batter looks thick, and microwave in 30-second bursts, stopping when the center is still a little soft.
Resting for a minute gives you a gooey middle without drying it out.
For a fudgy brownie in a mug, use a 16 oz mug, mix just until combined, and microwave in 30-second bursts based on your wattage, stopping when the edges look set but the center is still slightly glossy.
Letting it rest for 1 minute finishes the cooking without turning it rubbery.
You can double the batter recipe, but divide it into two individual mugs. Cook them one at a time for even cooking and the best texture.
