How to Make Flourless Chocolate Mug Brownie Recipe
Step 1: Mix the Batter
Start by grabbing a microwave-safe mug that’s at least 12 ounces to avoid spillage. Combine the cocoa powder, sugar, milk, vegetable oil, vanilla extract, salt, and baking powder if you’re using it. Whisk everything together thoroughly until the batter is smooth and there are no lumps hiding in the mix. This simple step ensures your brownie bakes up evenly with that silky, fudgy texture we love.
Step 2: Add Chocolate Chips
This step is totally optional but highly recommended if you adore extra gooey bites. Gently fold in the chocolate chips so that they’re evenly distributed throughout the batter. Watch how they melt into little pockets of richness during cooking—it’s pure chocolate bliss!
Step 3: Microwave the Brownie
Pop your mug in the microwave and cook it on high for one minute to one minute and thirty seconds. The timing depends on your microwave’s power, so start with one minute and check if the center has just set but still looks a bit soft—this gooeyness will make it heavenly. Overcooking can dry it out, so keep an eye on it the first time you try this recipe.
Step 4: Cool and Enjoy
After microwaving, let the brownie sit and cool for a couple of minutes. This pause helps it set perfectly while still being warm and gooey. Now’s the moment to add any toppings you love—go wild or keep it simple, the choice is yours!
How to Serve Flourless Chocolate Mug Brownie Recipe

Garnishes
Sprinkle some powdered sugar on top for a fancy touch, add a scoop of vanilla ice cream to balance the intense chocolate, or dollop whipped cream for that classic dessert vibe. Even a drizzle of caramel or chocolate sauce compliments this rich brownie beautifully, enhancing its decadence without overpowering the dense chocolate soul.
Side Dishes
A quick fresh berry salad or a few slices of banana make delightful, refreshing companions to this brownie. The tartness and natural sweetness of fruit contrast nicely with the rich chocolate, adding dimension to your dessert experience without adding complexity.
Creative Ways to Present
If you want to impress guests or just have fun, serve the brownie in little glass jars or ramekins topped with mini marshmallows toasted under a broiler for a campfire-inspired treat. You can also swirl peanut butter into the batter before microwaving for a luscious surprise or sprinkle chopped nuts on top for texture. The possibilities are endless and all delicious!
Make Ahead and Storage
Storing Leftovers
This brownie is best enjoyed fresh, but if you do have leftovers, cover your mug tightly with plastic wrap or transfer the brownie into an airtight container. Store it in the refrigerator for up to two days. Keep in mind it will firm up further, losing some of its warm gooey charm but still tasting delightful.
Freezing
While this brownie is ideal for immediate indulgence, you can freeze portions by scooping the baked brownie into a freezer-safe container. Freeze for up to one month. Thaw overnight in the fridge and then reheat to regain that fresh-from-the-microwave softness and flavor.
Reheating
To bring your brownie back to life, microwave it in short 10-second bursts until just warmed through. Avoid overheating to prevent drying out. A quick warm-up revives the gooey texture and makes it feel like a brand-new treat.
FAQs
Can I use other types of milk for this recipe?
Absolutely! This recipe is very flexible. Whether you prefer almond, soy, oat, or any other dairy-free milk, it works perfectly without compromising taste or texture.
Does the brownie taste very different without flour?
The flavor is intensely chocolatey and slightly richer due to the absence of flour. The texture is fudgier and more like a dense, rich truffle than a typical cakey brownie. It’s a delicious twist that chocolate lovers adore.
Can I make this recipe without a microwave?
If you don’t have a microwave, you can bake the batter in a small oven-safe dish at 350°F (175°C) for about 10-15 minutes. Keep a close eye to avoid drying out the brownie since ovens vary.
What if I don’t have baking powder?
You can skip the baking powder if you want a denser brownie. It’s optional and mainly adds a touch of fluffiness; the brownie will still be fudgy and delicious without it.
How can I make this recipe vegan?
Simply use a plant-based milk and replace the vegetable oil with melted coconut oil or vegan butter. Make sure your chocolate chips are dairy-free. You’ll have a vegan-friendly Flourless Chocolate Mug Brownie Recipe that’s every bit as good as the original.
