Microwave Mug Brownie Recipe
The Microwave Mug Brownie is your secret weapon for those moments when the chocolate craving hits and you need a rich, molten treat in minutes, not hours.

This single-serve delight satisfies your sweet tooth without any fuss or fancy equipment—just pure chocolate bliss made easy with the magic of your microwave.

Ingredients You’ll Need
This Microwave Mug Brownie is proof that simple, everyday ingredients can work wonders. Each one brings its own magic to the mug, from the earthy depth of cocoa powder to the creamy richness of chocolate chips. Don’t skip or skimp—these basics are the ticket to a brownie that truly satisfies!
- All-purpose flour: This is the backbone of your brownie, providing just the right amount of structure to hold together all the gooey goodness.
- Granulated sugar: Sweetness is a must, and sugar guarantees each bite is indulgently delicious.
- Unsweetened cocoa powder: The star of the show—cocoa adds that unmistakable, deep chocolate flavor.
- Pinch of salt: Never underestimate salt; it balances the sweetness and intensifies the chocolate flavor.
- Unsalted butter (melted) or coconut oil: Richness and moisture are the keys to fudgy brownies, and butter brings both to the party (plus, coconut oil is a fun dairy-free twist!)
- Water (or milk): Liquid helps both texture and tenderness; milk adds extra richness, while water keeps things light.
- Pure vanilla extract: A little vanilla rounds out the flavors and adds a warm, comforting aroma.
- Semisweet chocolate chips: Chocolate chips create melty pockets of chocolate—an irresistible surprise in every bite.
- Vanilla ice cream and chocolate syrup (optional): These are the perfect finishing touches for a true dessert experience!
How to Make Microwave Mug Brownie
Step 1: Whisk Together the Dry Ingredients
Start by grabbing your favorite microwave-safe mug—something that feels good to hold is always a plus! Add the flour, sugar, cocoa powder, and just a pinch of salt to the mug. Give everything a thorough whisk to ensure your cocoa and sugar are evenly distributed and there are no lumps hiding at the bottom. Mixing the dry ingredients first sets the stage for a smooth, uniform brownie batter.
Step 2: Add the Wet Ingredients and Mix
Next, pour in the melted butter (or coconut oil), water (or milk), and pure vanilla extract right on top of your dry mix. Use a spoon or mini-whisk to stir it all together. It takes just ten seconds to come together; you want the mixture to be fully combined but not overworked, so your Microwave Mug Brownie stays tender and fudgy. Don’t forget to gently fold in those semisweet chocolate chips—they’re what make each spoonful extra decadent!
Step 3: Microwave to Gooey Perfection
Place your mug in the microwave and cook on full power for 60 to 90 seconds. Microwave strengths vary, so start at 60 seconds and check if the top looks fully cooked—springy and no longer wet. If needed, zap it for another 10-30 seconds, keeping a close eye so it doesn’t overcook. The brownie should look set but stay delightfully moist. Let it cool for about 5 minutes—if you can resist—and watch it turn into a warm, fudgy masterpiece.
How to Serve Microwave Mug Brownie

Garnishes
To take your Microwave Mug Brownie to the next level, don’t hold back on garnishes! A scoop of vanilla ice cream on top slowly melting into the warm brownie is a match made in dessert heaven. Drizzle with chocolate syrup for a glossy, eye-catching finish—and if you’re feeling fancy, add a sprinkle of sea salt or a dusting of powdered sugar.
Side Dishes
While this mug brownie shines solo, it pairs perfectly with a handful of fresh berries for a little tartness to offset the chocolate. Try it with a glass of cold milk, your favorite coffee, or even a dollop of whipped cream. For a grown-up twist, serve it alongside a rich espresso or a splash of Bailey’s in your coffee.
Creative Ways to Present
Who says a Microwave Mug Brownie has to be plain? Layer your brownie with mini marshmallows for a s’mores vibe, or swirl in a spoonful of peanut butter before microwaving for a gooey surprise. Use fun mugs, festive sprinkles, or even layer two brownies with your favorite frosting for a mini mug cake “sandwich.” It’s all about making your dessert your own—don’t be afraid to play!
Make Ahead and Storage
Storing Leftovers
If you have leftover Microwave Mug Brownie (it happens, but rarely!), just cover your mug with plastic wrap or transfer the brownie to an airtight container. It will stay moist and delicious at room temperature for up to a day, or up to two days if refrigerated. Pop it in the fridge if you’re saving it for tomorrow—this helps keep it fresher for longer.
Freezing
Brownies in the freezer? Absolutely! Let your mug brownie cool completely, then gently remove it from the mug (a butter knife around the edge helps) and wrap it in plastic wrap or foil. Place in a freezer-safe bag or container. It’ll keep well for up to 2 months. When the craving hits, you’re just a quick zap away from gooey goodness.
Reheating
To enjoy your Microwave Mug Brownie just like new, reheat it in the microwave for 10 to 20 seconds until warmed through. If you’ve frozen your brownie, let it thaw on the counter for an hour or give it an extra burst in the microwave. Be careful not to overheat, or you’ll lose that perfect, fudgy texture.
FAQs
Can I make Microwave Mug Brownie vegan?
Absolutely! Swap the butter for coconut oil or a vegan butter, use plant-based milk or water, and check that your chocolate chips are dairy-free. The texture stays fudgy and delicious, with all the chocolatey goodness!
Why did my brownie turn out dry?
Microwaves cook quickly and unevenly, so be careful not to overcook your brownie. Start with 60 seconds, then add just a few more seconds at a time. The brownie should appear set on top but slightly soft inside for that perfect gooey center.
Can I double the recipe?
You certainly can! Either make two individual brownies in separate mugs, or use a larger microwave-safe bowl for a double batch. Just remember to increase the microwave time slightly and check doneness frequently.
Is it safe to microwave my mug?
Always use a microwave-safe mug, typically labeled on the bottom. Avoid anything with metallic trim, and consider the thickness of the mug—thinner mugs may heat up (and cook the brownie) faster, so adjust timing as needed.
Can I add nuts or other mix-ins?
Definitely! Feel free to fold in chopped walnuts, pecans, peanut butter chips, or even a swirl of caramel. Make your Microwave Mug Brownie truly your own by experimenting with your favorite flavor additions.
