2 Ingredient Mug Brownies

Can we talk brownies for a second?

I have a deep love for those sweet chocolaty bars and they will always have a special place in my belly.

I dig homemade but am definitely not one to snub my nose at a box mix. So when I saw this cleverly titled book 50 Fixes for Brownie Mixes (affiliate), from my friend Aimee at Like Mother Like Daughter, I knew I needed to add it to my collection. The first recipe I knew I needed to make? This brownie in a mug!

Recipe Features:

  • 2 Ingredients: The base for this recipe is literally TWO ingredients.
  • Single Serving: It makes a hefty single serving or two smaller servings.
  • Easy to Customize: You can add so many mix-in items to make this more customized to your tastes (see below).
50 Fixes for Brownie Mixes

I was pleasantly surprised by the wide variety of recipes included in this book. There is everything from brownie pancakes, brownie ice cream, brownie milk shakes, and MUG BROWNIES.

Basically what I’m saying is that you need to head into Costco or some other bulk warehouse and buy a bunch of brownie mixes so you can be prepared to make at least a dozen of these treats.

What You’ll Need:

This mug brownie with brownie mix is every chocolate lovers dream. Easy to make and minimal ingredients. Below is a quick breakdown. For measurements see the recipe card below.

  • Brownie Mix: Pick your favorite. This is where 99.9% of the flavor is going to come from so I suggest picking one that is super rich.
  • Water: Regular ol’ H2O.
Microwave Mug Cake

Step by Step Instructions:

Since the mug brownie is made without cocoa powder, AND took less than 2 ingredients and 90 seconds, I knew they it was THE recipe for me.

  1. Combine the brownie mix and water in a mug. Mix to combine.
  2. Microwave 90 seconds.
  3. Top with whipped cream, ice cream, or chocolate chips.

Hard to believe you can have a dessert ready in under five minutes, am I right? We topped ours with a little ice cream and chocolate syrup. We agreed that it gets two thumbs up.

It did turn out a little more cake like but that works for me since I prefer my brownies less fudge textured.

Mug Brownies Tips and FAQ’s:

NOTE BEFORE YOU START: This is a mug recipe that only uses two ingredients. It won’t have the same oven baked taste that the classic recipe you know and love has. 

HOWEVER, they are still amazing and perfect for a quick treat! 

Last tip, use a BIG mug or two smaller mugs.

This recipe has a love/hate relationship with my readers. Some people love it, some hate it. We’ve made it our mission to try ALL of the suggestions left below and here are a few of our FAVORITE mix in ideas:
Mini Chocolate Chips
A spoonful of Nutella
Vanilla Extract
Mayonnaise – Seems weird but a heaping teaspoon gives the brownies a fudgier finish.
Chopped pieces of your favorite candy bar.
Chopped nuts.
Mini marshmallows.
Crumbled cookies (hello OREO’s!)
Top with frosting or ice cream

What is the best brownie mix?

You really cannot go wrong with any quality brownie mix. Our personal favorite is Ghirardelli Triple Chocolate Brownie Mix . I mean, it is so full of chocolate flavor that you just cannot beat it. However, Betty Crocker Triple Chunk Brownie Mix and  Duncan Hines Dark Chocolate Fudge Brownie Mix come in a close second.

Do I need to add eggs to a box brownie mix?

Brownie mix has vegetable oil. While I'm not a fan of using vegetable oil, nothing about this is good for us. Lol. I mixed the ingredients as written and added a teaspoon of vegetable oil. Made all the difference. Then topped it with mini chocolate chips after the 90 seconds. Perfect fix for a sweet tooth moment.

Thanks for the tip, Steph!

ATTENTION! Cook for 90 seconds! Watch as it cooks. When it starts to bubble less, take it out! You can stop a mug cake then put it back in. Will not work!

Nutella will usually only work with the fudgy high end brands!

Mayo added is the trick! The fat and egg give it a little extra fudgy consistency.

@Jesseca, This has happened to me twice before. Once when I made them in a friends microwave and the wattage was much higher than mine, and once when I pulled it out too early and put it back in. I discovered that they need to be cooked in one go for the best results. Hope this helps!

Honestly haven't had this happen before. Do you have specifics? What type of cake mix? Wattage of the microwave? How long is "longer"? I'd love to help troubleshoot.

Not sure where I went wrong. I did the directions...sprayed the cup, mixed dry brownie mix with...I did the tsp of Nutella and 2 TB of water. I put it in for 60 seconds and it was still raw. I put it in for a little longer (30 sec max) and it still wasn't the way it should be. I gave it a try anyway and topped it will a scoop of vanilla ice cream. It ended up being really chewing and got hard...too hard to eat. It seems that it may be over cooked, but yet wasn't cooked enough. It still tasted good, as I'm not real picky with chocolate. I will definitely be trying again, but I might need some tips on what to do diffrrently. My microwave is 1100

We've found that some box mixes don't work well with the nutella mixed directly into the cake. We have started heating the nutella in the microwave and drizzling it over the top and then adding ice cream. It also will have a slightly different texture, but it shouldn't be hard and chewy. I'll test this version again today and see what I can figure out for you.
