Ingredients

  • All-Purpose Flour: The foundation that provides structure to your brownie, creating a tender crumb.
  • Granulated Sugar: Adds the perfect amount of sweetness to balance the rich chocolate flavor.
  • Unsweetened Cocoa Powder: The star ingredient that delivers intense chocolate taste in every bite.
  • Pinch of Salt: Enhances and rounds out the chocolate flavor, making it even more irresistible.
  • Vegetable Oil (or Melted Butter): Provides moisture and richness for a fudgy, gooey texture.
  • Milk: Makes the brownie extra moist and soft. Substitute with water for a firmer texture.

How to Make Brownie in a Mug

In just a few minutes, you can whip up a single-serving, molten chocolate treat right in your microwave. 

Don’t believe me? Check out these simple steps!

1. MIX DRY. In a microwave-safe mug, whisk the dry ingredients so they’re evenly distributed. 

2. ADD WET. Add the oil, milk, and vanilla and stir with a fork until the batter is smooth and all the dry ingredients are incorporated. Stir in the chocolate chips last.

3. MICROWAVE for 1 minute. It should look puffy but slightly wet in the middle. 

4. ADD extra chocolate chips (optional), then leave to rest for a few minutes. 

5. SERVE warm with a scoop of vanilla ice cream or a dollop of whipped cream.

A Note on Microwave wattage:

Mine is 1000-watt, and 60 seconds was just right.

If yours is higher (or you’re unsure) cook for 45 seconds and check the brownie. Then cook in 10-second intervals until it’s done.

Similarly, if yours is under 100 watts, you might need to cook the brownie for closer to 90 seconds.

Tips For the Best Brownie in a Mug

This fudgy brownie in a mug is my go-to for those late-night chocolate cravings or when I just need a quick pick-me-up.

But if you’ve ever made a mug cake before, you’ll know they can go wrong in a matter of seconds. 

So, read these tips before you start!

  • Mug size. Use a mug that holds at least 8-10 ounces to prevent the batter from overflowing during cooking.
  • Whisk well. Whisk the dry ingredients until no lumps remain for a smooth batter.
  • Avoid overcooking. Microwave for 1 minute, then check for doneness. It should look slightly wet on top, but it will set up as it cools. 
  • Optional mix-ins. Melt some peanut butter or Nutella in the mug and mix that in with the batter. Or add chopped nuts or extra chocolate chips for added flavor and texture.
  • Topping ideas. Top the warm brownie with a scoop of vanilla ice cream, a dollop of whipped cream, a drizzle of caramel or chocolate sauce, or a sprinkle of powdered sugar.

How to Store

Microwave mug brownies are best enjoyed fresh and warm out of the microwave for optimal taste and texture.

  1. What wattage microwave did you base this recipe on? I have both an 1100 and 1000 wattage. Which do I use? Please answer my question asap. I have all these ingredients on hand and would like to try this recipe. Thanks so much.

    • Hi Susan!
      Mine is 1000 watts and 60 seconds is just right for this mug cake.
      But if you’re unsure, start with 45 seconds and go from there.
      I’ve added a note about this in the post, so thanks for asking 🙂
