3 Ingredient Nutella Brownie Mug Cake

If you’re still looking for a dessert to make for your loved ones this weekend, I recommend my Nutella Brownie Mug Cake. It’s just 3 ingredients and cooks in the microwave. I’ve shared this recipe before, but it’s so good, I wanted to send a reminder.

This mug cake is so fantastically easy and is always such a hit when I make it. It’s chewy, fudgy, Nutella-y. It’s sure to be a great ending to your Valentine’s Day meal.

Don’t let the ramekins throw you off. You can’t actually make the desserts in the ramekins as the brownie rises about 2/3 in a 12 oz mug. The mug is ideal for mixing all the ingredients and for cooking the brownie. The one issue with this recipe is that it’s not the prettiest thing when it’s done. Unlike my traditional mug cakes, this doesn’t have a smooth cake surface. It actually looks quite blotchy and cracked when it’s finished. I actually did tinker with the recipe and made ones that looked prettier, but they just didn’t have that super chewy and fudgy texture anymore.

So I scooped it out and plated it in ramekins and topped with with some powdered sugar and strawberries to hide the imperfections. I may have eaten a couple bites from each brownie to make them fit into the ramekins. You know, for taste testing purposes.

Since I’m doing a Valentine’s Day theme here, I adjusted this recipe to make two brownie cakes. And I attempted to top them with heart-shaped strawberries slices. (Side note. why is it that when you actually need heart-shaped strawberry slices, none of them are coming out that way and when you don”t need them, you get so many that are?)

If you really want to kick it up a notch, you can top it with ice cream and fudge sauce and make a whole brownie sundae out of it.

(P.S. If you enjoy this mug cake, it’s featured in my 5-Minute Mug Cakes book.)

Recipe now updated with video! Please note, I only made one brownie for the video but the recipe below is for two. You can easily make one by halving all the ingredients. You can find all my recipe videos on my youtube page.

3 Ingredient Nutella Brownie Mug Cake

A Nutella brownie that is just 3 ingredients and cooks in the microwave.

Ingredients:

 
  • 1/2 cup + 2 tbsp Nutella
  • 1 large egg, gently whisked
  • 4 tbsp all purpose flour

Directions:

  1. The directions here are for making 2 mug cakes. You can easily halve the recipe if you just want to make one. Split the whisked egg evenly into two oversized microwave safe mugs (approximately 2 tbsp of whisked egg per mug). I used 12 oz mugs.
  2. Add 1/4 cup + 1 tbsp of Nutella into each mug. Add 2 tbsp of flour into each mug. Mix with a sturdy whisk until batter is smooth. Batter will be very thick, so you will need to exert some power in your whisking. 
  3. Microwave each mug separately for about 1 minute. Allow the brownie to cool slightly before eating. If you want an extra chewy brownie texture, allow the brownie to fully cool (about 20-30 minutes). For a nicer presentation, I recommend removing cake from mug and placing into a smaller plate or ramekin and then topping with powdered sugar, fruit, or ice cream on top.

  1. Oh my gosh I love this recipe. So genius!! 3 ingredients. Wow. Pinned!

  2. I don’t care how ugly it looks when it’s done – you had me at nutella and brownie. I just pinned this to my dessert board. I can’t wait to try it! 

  3. Just made this and it was absolutely delicious! So simple to assemble, and the end result is moist and fudgy. Probably my favorite mug cake recipe that I’ve tried- I will definitely be making this again and again!

  4. This looks really yummy but can you tell me the number of calories per mug? I’m kinda watching my weight but I think it’s time for a little indulgence.. :3

  5. You had me at “I may have eaten a couple bites from each brownie to make them fit into the ramekins. You know, for taste testing purposes.”
    You’re obviously my kind of cook! Thanks.

  6. Hi love the recipe! is it ok to use self raising or plain flour? Thank you! (big fan of you mug cakes)

    • i would suggest try with plain flour. dont use self rising because this cake isn’t supposed to have a rising agent

  7. hi! its look delish but i am confused(Add 1/4 cup + 1 tbsp of Nutella) add 1/4 cup of what

  8. I have a question, if I mixed the entire recipe( two servings) in one mug, would I have to double the cook time or leave it cooling any longer?

  9. This was delicious and my kids loved it! I cooked for 2 minutes in my 800 watt microwave and it came out perfectly. 

  10. I’m not sure how long to cook this, since I’ve tried your nutella mug cake (instead of brownie) and it took much longer than the indicated time. What should the brownie look like on top?

    • the brownie should basically look like the photo, minus the strawberries. it will be crackly and the batter should be completely cooked.

  11. is there a way to make this without flour?  looks amazing btw! 

  12. I forgot to add the additional T of Nutella, oops. 🙂 but it still turned out delish! I might just leave that out every time, why mess up a good thing?

  13. Is it possible to bake this in the oven? And how hot? (my english is not that good because i am dutch)

  14. 1/2 a cup????!!!!! What ingredient is this?!?!? 1/2 a cup is not an ingredient!!!!!

  15. My 11yo son asked if he could have a banana with some nutella. After he finished the banana I noticed he still had about 1/4 cup of nuttella in the bowl. (gross miscalculation on his part) So I looked this up and added 2 Tbsp flower and an egg white (whites=fluff, yolk=chew) and the result was fluffy and silky deliousness. Cheers!

  16. Can you also use wheat flour?

  17. Amazing recipe! I am new at baking and I was looking at some easy to make recipe for my mom’s birthday. I saw this recipe and decided to give it a go. Loved it. Looking forward to your new recipes 🙂

  18. Really good! I’m impressed how simple and efficient this recipe is. I put them only 30 seconds in the microwave though.
