Nutella Mug Brownie - It takes just 3 ingredients and just 1 Minute to make thee BEST EVER Brownie in a Mug!

Hi Bold Bakers!

We all know that dessert is the most important meal of the day so let’s get down to business with my Microwave Mug Nutella Brownie. If you’re a chocoholic like me, you appreciate a good chewy brownie. For a brownie this delicious, it’s incredible to learn that the recipe requires just three ingredients and takes just a minute to yield in the microwave.

How to Make a Brownie in a Mug

This easy brownie recipe is made with just a few ingredients: a bit of Nutella (store-bought or homemade nutella), a gently-whisked egg, and all-purpose flour. Like most baked goods, whisk your wet ingredients together first then add them to your dry. Once your batter is ready, your homemade brownie is ready for the microwave–the perfect nutella snacks.

Why Use A Microwave?

Microwaving your brownie in a mug will actually steam any liquid in your batter from the inside out rather than the outside in, meaning you’ll have as chewy of a brownie as its traditionally-baked predecessor.

Cooking time given is based on my 1200W Panasonic Inverter Microwave so your timing might vary. I suggest checking it after 1 minute of baking and go from there. If your brownie is overcooked, it will dry out and harden. Your microwave brownie will be done once the top has just firmed.

I’ll admit, I was sceptical at first but it turned out really good!

Hi Gemma

Which egg substitute would you recommend for this recipe? I generally use natural yogurt when making brownies in the oven but wondered if you would recommend something different.

Thanks,

Kerry

OMG WELL THAT WAS JUST DELICIOUS!! I was a bit sceptical after my mug doughnut disaster this morning, and since this just seemed very quick and easy but looked very yummy, I thought it was too good to be true! But after putting it in my microwave and adding some vanilla ice cream and had a taste, I was WOWED!! Very very yummy and tasted just like a perfect nutella brownie despite how easy it was, will defo be making again and defo recommend!!!!!!

All I did differently was use a different brand of chocolate spread and it got all oily and gross. It smelled burnt before it was even cooked.

The Nutella makes this a little overly sweet, but if you sub out some of it for peanut or almond butter (unsalted), then the sweetness is milder. If you sub the flour out for oat flour (which is what I did), then you can even turn this into a healthy breakfast. Just add cocoa powder and maple syrup (or any other sweetener) to taste before you put it in the microwave. 🙂

Mug cakes always turn out a little spongy though. I find peanut butter is the perfect fix to this. They turn out creamy with just a few spoons of peanut butter into the mix. I’ve been trying to find a substitute ingredient that can make a mug cake creamy but so far have not found one.

Mug cakes perfect for quick snacking when studying. 😀
Hope my mum doesn’t kill me for taking so much of her Nutella at once though.
