Mug Brownie Ingredients / What You Need

Make sure to scroll down to the recipe card at the bottom of this post for the full recipe and instructions.

  • Vegetable oil. You can use any type of light colored oil like canola oil as well.
  • Water. You can also use brewed coffee in place of water for a more intense chocolate flavor.
  • Vanilla extract. This amps up the flavor of the chocolate.
  • Granulated sugar
  • Unsweetened cocoa powder. Any brand will work, you can even use Dark cocoa powder or Dutch processed. Whatever you have in your pantry is fine!
  • Kosher salt
  • All purpose flour
  • Semi-sweet chocolate chips. You can also use mini chocolate chips, or even peanut butter or white chips.

How To Make A Brownie In A Mug:

  • All you do to make a mug brownie is mix all the ingredients in your favorite large mug and pop in the microwave for 90 seconds! Of course all microwaves are a little different, so make sure that the brownie is set on the inside and a toothpick inserted in the center comes out clean.
  • Top it off with some ice cream, hot fudge, or powdered sugar for an extra special dessert!
  • You don’t even need to grease the mug!

What Can You Add Into Your Mug Brownie:

I like to add chocolate chips in my mug brownie, as I included in the recipe, but you don’t have to stop there! Get creative! Here are a few fun ideas:

  • Peanut Butter Chips
  • White Chocolate Chips
  • A tablespoon of peanut butter dropped right into the middle of the batter before you microwave it.
  • A tablespoon of Nutella, same as the peanut butter.
  • A dusting of powdered sugar
  • A spread of frosting on top when it’s warm.
  • Ice cream!!
  • Hot Fudge
  • Whipped cream

What Size Mug Should You Use?

A large mug is necessary for this recipe to cook properly. If you use a smaller mug, they are generally a little narrower in diameter, which doesn’t allow for the centers to cook and the edges over-cook.

TIP: I recommend using a 12 – 14 ounce mug, which gives the cooking a little more surface area. Most mugs nowadays are that larger size, so most likely you have one right in your cupboard! If you don’t have a larger size mug, you can even use a small bowl.
