Here’s What You’ll Need for Your Brownie in a Mug
3 tablespoons granulated sugar: This sweetener helps your brownie feel indulgent and delicious! Just the right amount of sugar gives you that satisfying sweetness.
3 tablespoons all-purpose flour: Essential for structure, this flour keeps your brownie light yet rich. And yes, you can swap this for whole wheat flour if that’s what you have!
1 1/2 tablespoons unsweetened cocoa powder: Because what’s a brownie without chocolate? This cocoa powder provides that deep chocolate flavor that we all crave!
Pinch of salt: This tiny addition elevates the flavors! A couple of pinches of salt will balance out the sweetness.
2 tablespoons chocolate chips: You can use semi-sweet or dark chocolate, whichever makes your heart sing! Or, if you’re feeling wild, mix in some peanut butter chips for a twist!
1 1/2 tablespoons vegetable oil, melted coconut oil, or melted butter: Choose your fat, my friend! Each option adds a unique richness that helps keep your brownie moist and fudgy.
3 tablespoons milk: You can use dairy or non-dairy milk; I’ve tried it with almond milk, and it’s still amazing!
1/4 teaspoon vanilla extract: This aromatic ingredient brings warmth and enhances that lovely chocolate flavor.
Optional toppings: Ice cream, whipped cream, powdered sugar, berries, because sometimes you just need ALL the indulgence!
How to Make This Brownie in a Mug
Start by grabbing your favorite microwave-safe mug (you know, the one that screams “I belong in this kitchen?”). Add 3 tablespoons of granulated sugar, 3 tablespoons of all-purpose flour, 1 1/2 tablespoons unsweetened cocoa powder, and a pinch of salt. Stir together with a small whisk or fork until everything is nicely combined and lump-free. We want a smooth base for our brownie!
Now, let’s add in some delightful mix-ins! Stir in 2 tablespoons of chocolate chips for that melty chocolate goodness we all love.
Next, pour in 1 1/2 tablespoons of vegetable oil (or your choice of fat), 3 tablespoons of milk, and 1/4 teaspoon of vanilla extract. This mix is going to be a rich and creamy concoction! Stir it up with a spoon or small spatula until everything is just combined, don’t overmix! We want to keep that fudgy texture intact.
Here’s where the fun happens: sprinkle a few more chocolate chips on top! They’re not just for show; they’ll melt beautifully in the microwave.
Pop your mug in the microwave and cook for 60 seconds. Seriously. Just a minute! After that, check to see if it’s done by ensuring there’s no raw batter, fudgy chocolate chips are the goal here, though! If it needs some extra time, continue microwaving in 10-second increments until you reach that perfect doneness.
The smell is going to be utterly heavenly, trust me on this. Let it cool slightly, then dive right in! Top it off with some ice cream, whipped cream, or fresh berries for a divine dessert experience.

Reheating: For the best results, reheat in the microwave for 10-15 seconds until it’s warm and fudgy again. Just don’t cook it too long or it could dry out.
Freezer-Friendly: While it’s really best fresh, if you have leftovers, you could freeze them in an airtight container. Just thaw in the fridge overnight before reheating.
