Ingredients You’ll Need
These ingredients are wonderfully simple but crucial for that chewy, chocolatey texture and perfect balance of sweetness. Each staple ingredient plays its role, from the cocoa powder lowering bitterness to the oil adding moisture and richness.
- Granulated sugar: Adds the perfect amount of sweetness to balance the cocoa’s bitterness.
- All-purpose flour: Provides structure to keep the brownie firm yet tender.
- Unsweetened cocoa powder: Brings deep, authentic chocolate flavor and dark color.
- Pinch of salt: Enhances and complements the chocolate notes.
- Chocolate chips: Melt into gooey pockets of chocolate, creating texture and extra richness.
- Vegetable oil (or melted coconut oil or butter): Keeps the brownie moist and luscious.
- Milk: Adds moisture to help everything blend into a smooth batter.
- Vanilla extract: Gives a warm, aromatic depth to the flavor.
- Optional toppings (ice cream, whipped cream, powdered sugar, berries): Add flair, extra sweetness, and contrasting textures.
How to Make Brownie in a Mug
Step 1: Combine Dry Ingredients
Start by placing the sugar, flour, cocoa powder, and a pinch of salt right into your favorite microwave-safe mug. Using a small whisk or fork, mix everything thoroughly until there are no lumps and the cocoa blends evenly. This careful step ensures your brownie batter will have a smooth and even texture without any stray pockets of dry flour or cocoa.
Step 2: Add Chocolate Chips
Once your dry mix is ready, stir in the chocolate chips. They don’t just provide bursts of melted chocolate as you bite down, they also slightly thicken the batter, helping create that fudgy texture that makes a Brownie in a Mug unforgettable.
Step 3: Stir in Wet Ingredients
Now, pour in the oil, milk, and vanilla extract. Use a spoon or small spatula to gently fold everything together until just combined. Avoid over-mixing because you want to keep the brownie tender and moist. The oil and milk emulsify with the dry ingredients to form a luscious brownie batter base.
Step 4: Microwave to Perfection
Sprinkle a few chocolate chips on top for an extra melty finish, then place the mug in your microwave. Heat on high for 60 seconds initially. Check to see if it’s done—the surface should be set but still soft inside, with no raw batter visible, though it’s okay if some chocolate chips stay fudgy. If not fully cooked, microwave in 10-second increments until it reaches your perfect level of doneness. Remember, microwave strength and mug size can affect cooking time.
How to Serve Brownie in a Mug

Garnishes
The beauty of this quick treat is how easily it elevates with simple garnishes. A scoop of ice cream on top instantly creates a warm-and-cold dessert experience that’s pure bliss. Whipped cream adds airy sweetness and lightness. Sifting powdered sugar creates a pretty presentation and a delicate contrast to the rich brownie. Fresh berries can cut through the chocolate heaviness with bright, tart notes.
Side Dishes
While rich enough on its own, your Brownie in a Mug pairs beautifully with fresh fruit salads or a crisp salad to balance the indulgence. Coffee or a glass of cold milk complements the chocolate flavors and enhances the overall experience. For an adult twist, a splash of espresso or a favorite liqueur can make the moment even more special.
Creative Ways to Present
Try serving your Brownie in a Mug with edible flowers or colorful sprinkles for a festive touch. Pulse some nuts or sea salt over the top for an exciting contrast of textures and flavors. You can also layer the brownie with alternating scoops of ice cream in a clear mug to showcase those gooey chocolate chips and fudgy layers—talk about eye candy!
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover Brownie in a Mug, cover the mug tightly with plastic wrap or transfer the brownie to an airtight container. Store it in the refrigerator for up to 2 days. The texture will firm up but still be delicious when warmed.
Freezing
Because this dessert is best fresh and warm, freezing isn’t ideal. However, you can freeze the dry mix separately in a small container or zip bag to save time on future cravings. When ready, just add the wet ingredients and microwave.
Reheating
To enjoy leftover brownie, microwave it for about 20-30 seconds or until warmed through. Be careful not to overheat, or it may become dry. Add a splash of milk before reheating to help restore moisture if desired.
FAQs
Can I use a different type of milk?
Absolutely! Whole milk, skim, almond, soy, or any milk you prefer will work just fine. Just keep in mind the fat content can slightly affect the richness and texture.
What if I don’t have cocoa powder?
Cocoa powder is key for that authentic chocolate taste, but if you’re in a pinch, you could try melted chocolate or use hot chocolate mix with adjusted sugar amounts, although the flavor will be less intense.
Can I make this Brownie in a Mug vegan?
Yes! Use dairy-free milk like almond or oat milk, substitute the butter for coconut oil or vegan margarine, and double-check your chocolate chips are vegan-friendly. The recipe translates beautifully into a vegan treat.
How can I make this brownie less sweet?
Reduce the sugar by a tablespoon or use a darker cocoa powder to balance sweetness with bitterness. You can also skip the toppings that add extra sugar.
Is the cooking time the same for all microwaves?
Microwave power varies, so cooking times are approximate. Start with 60 seconds and then add 10-second increments if not done. It’s better to undercook and check than overcook and dry out your Brownie in a Mug.
