Just because you don’t have an oven, doesn’t mean you can’t make delicious baked goods! If you have had a craving for something sweet, but only have a microwave, don’t worry, we’ve got you covered. This is an easy dessert recipe to make brownies in the microwave.

It’s full of chocolate flavor, with a fudgy texture just like regular brownies. To make it you'll need flour, cocoa powder, sugar, eggs, and butter. And of course, chocolate chips, just to give it that extra something. This will be the easiest brownie recipe you’ll ever make (and we even have a few ways to customize the recipe!). Just what you need to satisfy your sweet tooth.

Microwave Brownies Ingredients

Butter – the butter adds richness to the brownies. Oil can also be used, but the brownie will be softer.

Sugar – obviously sugar adds sweetness, but it also creates the right texture in your brownie. If you leave the sugar out, the brownies will be hard and dry. Brown sugar adds an extra flavor of caramelization and makes them more moist and chewy.

Cocoa Powder – the cocoa powder gives an extra cocoa flavor.

Eggs – this binds the brownie batter together and gives it rise.

Flour – the flour together with the eggs, holds the brownies together. Use all-purpose flour or see substitutions below.

Chocolate Chips – this makes the brownie fudgy.


How To Make Brownies In A Microwave

Place the butter in a large microwave-safe bowl and microwave on high (about 900W) in 30-second increments until the butter has melted completely. Mix in the sugars. Sift in the cocoa and beat in the eggs. Use the sieve again to add the flour. Mix the batter and then fold in the chocolate chips.

Use a folded piece of towel paper or parchment paper, and butter to grease a microwave-safe glass container. Pour in the batter and sprinkle with a few more chocolate chips.

Bake in the microwave on high, full power for about 5 minutes, that's it! To remove the cake, use a knife and slide it around the edges of the cake. Flip to remove.

Can You Make Microwave Brownies In A Mug?

Yes, you can! To make this recipe in a mug, divide the batter equally into cups with at least a 1-cup measurement. Add the chocolate chips and microwave for 1 minute and 50 seconds.


Tips for making the Best Microwave Brownies

For a lazy, shortcut version, use a store-bought brownie cake mix!

If you don't want to use butter, you can replace it with oil.

If you want, you can leave out the cocoa powder and add melted chocolate.

Make a healthier, keto-version of this brownie by using almond flour instead of flour, and using erythritol instead of sugar.

Of course, you can make this recipe in the oven too! Just use an oven-safe baking tin!

If you want to leave out the egg, you can substitute it with 1 tablespoon ground flaxseed mixed with 3 tablespoon water or ¼ cup (4 tablespoons) apple sauce.

How To Store and Soften Microwave Brownies

The microwave brownies can be stored at room temperature for up to one day, or in the fridge for up to 4 days, closed in an airtight container. keep in mind that if your brownies are too hard, you can soften them using the microwave. Just wrap each piece with damp paper towels and heat them in the microwave on medium heat for about 5-10 seconds to make them soft and moist again.
