I first started making mug cakes way back in the day when I was in college. My mom used to send me little kits – or prepackaged individual cakes and brownies. The idea was that you tossed the dry ingredients in a microwave-safe cup or bowl, and then add water, vanilla, and oil and you had cake!

What a treat that was for a poor college student like me! Do keep scrolling for a really cute idea I had an idea that would a fun Valentine gift for your college student, BFF, or workmate too! Here is a little preview:mug brownie wrapped in valentine paper with raffia ribbon and directions

There will be directions and a downloadable printable below. This would be a really cute little gift for someone special who needs a little love:)

Are Brownies in a Mug Vegan?

The difference is that back in the day, when my mom would make her “Cake Kits”, she used an angel food cake mix as part of the dry ingredients because an angel food cake mix contained egg whites. We don’t do that if we are making a vegan cake or brownie though.

It took me many trials and errors to get a vegan mug cake just right. This vegan brownie in a mug is the first one that I’m sharing with you!

What Kind of Mugs Should I Use for  Mug Cake or Brownie?

  • The most important factor to consider is that the mug should be microwave safe! It seems obvious, but do make sure. A mug that is not meant for the microwave may get very hot to handle, yet not allow the inner contents to properly cook. It might also break, causing damage to your microwave.


  • The next important factor to consider is that your mug should probably be a boring plain white mug. I have found, through experimentation, that the cute colored mugs just don’t heat as consistently. I think the color must either absorb or reflect the heat. Feel free to experiment with your colored mugs. I just can’t guarantee the cooking time. 


How to Make Vegan Brownies in a Mug:

You can either mix everything together in separate bowls and then carefully pour the mixed ingredients into the mug before microwaving, or you can just go ahead and mix things up in the mug. This is part of the fun in my opinion! 

If you choose to mix your brownie in the mug, it’s important that you carefully clean the sides of the mug with a paper towel before microwaving.

Wipe the inside of the cup before microwaving or your finished product will look messy.

Otherwise, the cup will look really messy! Unless you don’t care…you are eating a brownie in a mug and maybe these things just don’t matter!

It will still taste fabulous!

The Dry Ingredients

Start with the dry ingredients. Make sure that the cocoa powder and brown sugar have been thoroughly broken up and mixed until everything is quite powdery looking. Then go ahead and add in the chocolate chips.dry ingredients mixed in mug for vegan brownie.

Are chocolate chips vegan?

They can be, even if they aren’t labeled vegan. Read the back of the package and make sure yours do not include dairy. I can not guarantee that the sugar used is vegan though. I like to use these dairy-free chocolate chips I buy on Amazon. Mini chips are the perfect size for these single size servings of brownies. 

The Wet Ingredients:

You can either choose to just dump them in the mug and mix well or do as I did and mix the wet ingredients together in a bowl first and then dump them into the mug with the dry ingredients. It is less messy this way – but the flavor and texture will be the same either way. 

Why Vinegar in the Brownies?

You know, it’s just my little special touch that makes the texture and flavor better. It’s like buttermilk pancakes vs regular pancakes. It’s just a different flavor and texture. Adding the vinegar with the milk works the same as adding buttermilk….mostly. 

The Special Finishing Touches:

I sprinkle a few chocolate chips and these vegan sprinkles on top just for fun!

How Long do I Microwave the Brownie Mug?

This is a tricky one because not all microwaves cook the same. I microwave for 90 seconds. The mug brownie will be done when it is no longer wet on top and is somewhat firm to the touch. You can always put it back in for 10-second increments up to about 30 seconds. Don’t overcook though or your brownie will be too dry. This brownie pictured below needs to cook a little longer:

Serving Suggestion? 

Top with some vegan ice cream of course! Eat while still warm and the ice cream will get nice and melty. Yum!

The Valentine Craft/Gift:

I thought it would be super cute to make a little valentine’s gift for some of my sweet friends. tied and finished mugs with cute red valentine wraps with hearts, directions on paper mug, tied with raffia ribbon

  • I mixed the dry ingredients in each mug,
  • wrapped each in the valentine treat bags you can get at any store this time of year,
  • made some cute tags with instructions to make the brownie mug,
  • backed them with colored card stock,
  • and then tied it off in raffia ribbon which I found on Amazon.

Dry Ingredients

  • 3 Tablespoons flour
  • Tablespoons brown sugar packed
  • 2 Tablespoons cocoa powder
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt use less if desired
  • 2 Tablespoon vegan chocolate chips more for sprinkling on top

Wet Ingredients

  • 4 Tablespoons plant milk of choice
  • 3/4 teaspoon white vinegar
  • 1/2 teaspoon vanilla extract
  • 2 ½ Tablespoons vegetable oil like melted coconut, avocado, or corn


  • In a 12-14 ounce microwave-safe mug, mix together dry ingredients: flour, brown sugar, cocoa powder, ground cinnamon, salt, vegan chocolate chips. Set aside
  • In a separate small bowl, measure out the plant milk. Pour the vinegar and vanilla into it and then the oil.
  • Give the liquids a stir and pour all at once into the mug with dry ingredients. Mix well, ensuring the dry ingredients from the bottom of the mug are well incorporated.
  • Put in a microwave. Microwave times will vary. Heat on high for about 90 seconds till the top is no longer shiny and wet. If you need to microwave longer, do it in 10-second increments.
  • Allow cooling slightly before eating. Top with sprinkles, or vegan vanilla ice cream.


Special Note:
The ingredients were developed for one single serving size - or one mug. If you want to batch prepare the dry ingredients for six brownie mugs at a time follow these ingredient amounts:
1 cup plus 2 Tablespoons flour
3/4 cup plus 3 Tablespoons brown sugar
3/4 cup cocoa powder
1 1/2 teaspoon ground cinnamon
1 1/2 teaspoon salt
Mix all together into a mixing bowl.
You will need 3/4 cup chocolate chips BUT - Hold off on the chocolate chips till the dry ingredients are measured out in the mugs and add 2 Tablespoons to each of the 6 mugs. If you mix the chips in all at once with the dry ingredients, they will sink to the bottom of the bowl  and not distribute evenly into each mug. 
IMPORTANT - you will measure out 1/2 cup dry mix for each cup one at a time BUT you will take out 1 teaspoon. This is the exact amount needed for each mug - 1/2 cup less 1 teaspoon.
One teaspoon might seem trivial - but ingredients for this individual-sized brownie mug were developed for exactly this proportion. 
NOW add in the 2 Tablespoons chocolate chips and mix together. 
The wet ingredients are the same as above as they will be mixed and  added to each cup separately.
