This recipe calls for some pantry staples that you likely already have on hand, each playing a crucial role in creating that perfect fudgy brownie texture and deep chocolate flavor. From the cocoa powder that delivers the chocolate punch to the oil that keeps things moist, every ingredient counts.

3 tablespoons granulated sugar: This sweetens the brownie and balances the cocoa’s bitterness perfectly.
3 tablespoons all-purpose flour: The backbone of the brownie, providing structure without making it cakey.
1 ½ tablespoons unsweetened cocoa powder: Gives that rich, intense chocolate flavor that’s essential for a fudgy brownie.
Pinch of salt: Enhances the sweetness and deepens the chocolate notes.
2 tablespoons chocolate chips plus more for topping: Adds pockets of melty chocolate that take indulgence up a notch.
1 ½ tablespoons vegetable oil (or melted coconut oil or butter): Keeps your brownie moist, tender, and fudgy.
3 tablespoons milk: Binds everything together and keeps the batter smooth.
¼ teaspoon vanilla extract: Boosts flavor with a warm, aromatic touch.
Optional toppings (ice cream, whipped cream, powdered sugar, berries): For when you want to make your mug brownie even more special.

How to Make Fudgy Mug Brownie Recipe

Step 1: Mix the Dry Ingredients

Start by placing sugar, flour, cocoa powder, and a pinch of salt directly into your microwave-safe mug. Use a small whisk or a fork to stir these dry ingredients together until everything is evenly combined and there are no lumps—this ensures a smooth batter and consistent flavor in every bite.

Step 2: Add the Chocolate Chips

Stir 2 tablespoons of chocolate chips into the dry mixture. These will melt during cooking, leaving magical pockets of gooey chocolate throughout your brownie, making each spoonful a delightful surprise.

Step 3: Incorporate the Wet Ingredients

Next, pour in the vegetable oil (or your choice of melted coconut oil or butter), the milk, and vanilla extract. Gently mix everything with a spoon or small spatula until just combined. Be careful not to overmix—that’s the secret to keeping your brownie nice and fudgy rather than cakey.

Step 4: Top and Microwave

Sprinkle a few extra chocolate chips on top of your batter. This little touch creates an irresistible melted chocolate crust on the surface. Microwave the mug on high for 60 seconds. Cooking times can vary by microwave strength and mug size, so if your brownie is still a bit underdone, continue cooking in 10-second bursts until you see a set but fudgy texture (a little melted chocolate on top is perfectly fine).

Step 5: Enjoy!

Once cooked, grab a spoon and dive into your warm, fudgy masterpiece. This brownie is best enjoyed immediately, especially when paired with your favorite toppings like ice cream or whipped cream.

Garnishes

Adding a garnish can elevate your brownie experience tremendously. A scoop of creamy vanilla ice cream melting beautifully on top, or a dollop of fluffy whipped cream adds a wonderful contrast to the rich, warm chocolate. Don’t forget a light dusting of powdered sugar or fresh berries for a pop of color and freshness that cuts through the sweetness.

Side Dishes

Though this mug brownie can stand proudly on its own, pairing it with a cool side like fresh strawberries or a tangy raspberry coulis can balance the richness and create a dessert you’ll crave over and over. A cup of strong coffee or a creamy latte is also a perfect companion for this chocolate treat.

Creative Ways to Present

Try serving your Fudgy Mug Brownie Recipe in different mugs to match the occasion or your mood. Transparent glass mugs showcase the layers and chocolate chips beautifully. Or get whimsical with themed mugs for parties or cozy nights in. You can even decorate the rim of the mug with melted chocolate and sprinkles for a festive touch that’s sure to impress anyone lucky enough to share it with you.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers, cover the mug tightly with plastic wrap and pop it in the fridge. The brownie will keep well for a day or two, though it’s best enjoyed fresh. When stored properly, the brownie will retain much of its fudgy texture but might firm up a bit—still delicious!

Freezing

Freezing the brownie in the mug isn’t ideal due to the mug itself, but you can transfer the brownie to an airtight container and freeze it for up to a month. When ready to enjoy, thaw overnight in the fridge and reheat gently in the microwave. Freezing may slightly change the texture, but you’ll still have a decadent dessert waiting for you.

Reheating

To warm up your brownie, microwave it in 10 to 15-second bursts until heated through. Keep an eye on it to avoid overcooking, which can turn the fudgy magic into dryness. Adding a little scoop of ice cream right after reheating will bring back the warm-and-cool contrast that makes this brownie so delightful.

FAQs

Can I use other types of flour in this Fudgy Mug Brownie Recipe?

All-purpose flour works best for the texture in this recipe, but you can experiment with gluten-free blends if needed. Just keep in mind that the texture might vary slightly depending on the flour’s absorbency.

What if I don’t have unsweetened cocoa powder?

If you only have sweetened cocoa, reduce the sugar slightly to balance the sweetness, but unsweetened cocoa powder is preferred to get that deep chocolate flavor without extra sugar.

Can I make this brownie vegan?

Absolutely! Use a plant-based milk like almond or oat milk, and swap the butter for coconut oil or a vegan butter alternative. Make sure your chocolate chips are dairy-free as well.

How do I know when the mug brownie is done?

The edges should look set and the top mostly firm but still slightly soft in the center. Don’t worry if the chocolate chips are still melty—that’s the sign of a perfect fudgy center.

Is this recipe adjustable for larger servings?

Yes, you can double the ingredients and use a bigger mug, but keep in mind the microwave time will increase. Start with 90 seconds and then add 10-second increments until cooked through.
