Why You’ll Love This Foolproof Brownie in a Mug Recipe
- Ready in just 5 minutes, perfect for busy weeknights or last-minute cravings.
- Uses simple pantry staples you probably already have on hand.
- Has a fudgy, rich texture, never cakey or dry.
- Single serving means no leftover brownies to worry about or waste.
Choosing Your Ingredients for the Perfect Fudgy Texture
For a dense, fudgy brownie, I recommend using oil instead of butter. Oil creates a moister, chewier texture, while butter tends to make it slightly more cake-like and rich. As for cocoa powder, both natural and Dutch-processed work well here—the difference won’t affect this quick brownie much, so use whichever you have. The real secret? No eggs. Leaving eggs out avoids the spongy, cakey texture typical of mug cakes and helps keep the brownie fudgy and luscious.

Notes
The Best Equipment for a Microwave Brownie
A wide, microwave-safe mug is your best friend for this recipe. Its broad shape helps the brownie cook evenly, preventing edges from drying out while the center remains raw. Aim for a mug size between 10 and 14 ounces; this amount keeps batter contained and avoids messy overflows. Tall, narrow mugs tend to cook unevenly, so definitely choose a wider one for the best results.
Ingredients
- 3 tablespoons granulated sugar
- 3 tablespoons all-purpose flour
- 1 ½ tablespoons unsweetened cocoa powder
- Pinch of salt
- 2 tablespoons chocolate chips (plus more for topping)
- 1 ½ tablespoons vegetable oil, melted coconut oil, or melted butter
- 3 tablespoons milk
- ¼ teaspoon vanilla extract
- Optional toppings: ice cream, whipped cream, powdered sugar, berries
How to Make a Brownie in a Mug
- Combine the dry ingredients: Place 3 tablespoons granulated sugar, 3 tablespoons all-purpose flour, 1 ½ tablespoons unsweetened cocoa powder, and a pinch of salt in a mug. Whisk with a small fork until smooth and lump-free. Stir in 2 tablespoons chocolate chips.
- Add the wet ingredients: Pour in 1 ½ tablespoons vegetable oil (or melted coconut oil or butter), 3 tablespoons milk, and ¼ teaspoon vanilla extract. Stir gently with a spoon or rubber spatula just until combined. Avoid over-mixing—the batter should be slightly uneven.
- Top and microwave: Sprinkle a few chocolate chips on top. Microwave for 60 seconds, then check the center. If it isn’t set, cook in 10-second bursts until done (the brownie should be fudgy, not runny). The exact timing will depend on your microwave’s wattage; consult this guide for recommended cooking times.
- Serve immediately: Enjoy warm straight from the mug, optionally topped with ice cream, whipped cream, powdered sugar, or fresh berries.
