Here’s the story of this Microwave Mug Brownie, or Brownie Mug Cake, whichever your heart desires. So, four days ago I had a craving. For a brownie.

You know, those cravings? The ones you try to ignore but no matter what everything begins to look like a brownie? Well yeah, I ignored it for a day. And it only got worse.

Then I tried to buy one, that was a disaster. Took two bites out of it and threw it away. I didn’t want to bake a whole batch…because then I might eat a whole batch.

Wait, what? Bake just one? In 60 seconds? Seriously? That’s a brilliant idea! That sounds like a Microwave Mug Brownie!


So, that’s 4 tbsp of flour, 4 tbsp of sugar, 2 tbsp of oil, 2 tbsp of cocoa powder, 2 tbsp of water, and 1/4 teaspoon of salt mixed with the flour. Looking good so far. Now we need a cup.

Meet my favourite cup. Hi cup.

And my favourite M&M. You know, despite everyone thinking pink is my favourite colour, I actually prefer green. My walls are green. This bed sheet i’m lying on while typing this is green. My towel is green. Okay, you get the point.

Pink is second.

Okay let’s mix the water with the oil, and add in 1/2 teaspoon of vanilla extract.

Okay, add the sugar and the cocoa powder. Now mix! You can use a fork, that’s what I did.

Now the flour and the salt. Get ready for it.

PLEASE DO NOT EAT THIS LIKE THIS. Well, technically, you could, since there are no raw eggs or so…but come on we only have to wait like a little bit to cook it! Hold on!

And because I’m greedy Just for kicks I added in some chocolate chips. Yes, I opened an entire container of chocolate chips to get a tablespoon. The craving was that bad.

Into the microwave you go! Say a little prayer that it doesn’t explode everywhere.
I put mine on 60 seconds – it was perfect.

Come to Mama.

Can I just take a minute while this is cooling to admit that I ate this WAY too quick, burnt myself and forced myself to be patient. Have you ever smelt brownies baking? Yes, well imagine that happening in less than a minute. I couldn’t wait, literally.

Let’s dig in.

This Microwave Mug Brownie was actually, like, really good.
Really really good.
All the delicious flavours of a brownie, chewy and fudgy. Oh yes.

She’s also very happy.

  • 2 tablespoons oil
  • 2 tablespoons water
  • 4 tablespoons brown sugar or coconut sugar, white sugar or cane sugar
  • 2 tablespoons cocoa powder
  • 4 tablespoons flour
  • ¼ teaspoon sea salt
  • ½ teaspoon vanilla extract
  • 1 tablespoon chocolate chips + extra for on top


  • In a mug, add in the oil, water, sugar and cocoa powder. Whisk together for about 15 seconds. Add in the flour, sea salt and vanilla extract.
  • Stir to combine for about 30 more seconds to ensure it’s all incorporated, ensuring you get the bottoms too. Add in the chocolate chips and fold in. Feel free to sprinkle some of them on top.
  • Place in your microwave for 60 seconds. It's okay if it's slightly undercooked because it'll continue to cook while it cools. It's better for it to be slightly undercooked than overcooked. Remove and let cool for about 3 to 5 minutes. Trust me!
  • Dig in, and enjoy!

    Great recipe! Don’t overcook – it may look a little undercooked when it comes out of the microwave but you don’t want to go any longer. Made it several times and this recipe is a keeper. Great to make a single serving than have a tray of brownies around the kitchen. Thank you, Jessica!
