Brownie in a Mug

Oh my. We’re doomed. My young friends Reilly and Alden just showed me how they make single serving brownies, in a mug, in a microwave. Takes 5 minutes.

We did experiment a bit. Turns out that you really should not use extra virgin olive oil for this recipe, it’s too strongly flavored. Corn oil or canola oil work best.

A pinch of salt helps make the chocolate more chocolate-y. I’ve added some vanilla and a tiny bit of cinnamon; you could also add a speck of instant coffee to take it up a notch.

Mug Brownie

The brownie lacks for structure (no egg) but that’s okay because it’s contained by the mug. When it’s done, it’s HOT. Perfect for topping with a little vanilla ice cream or whipping cream.

The trick is getting the cooking time right for your microwave. Every microwave oven model is different.

Our 1000 watt microwave cooked these brownies in a mug perfectly at a minute 40 seconds. If you have a stronger microwave it will likely take less time. Enjoy!

 

Brownie in a Mug Recipe

  • Prep time: 3 minutes
  • Cook time: 2 minutes
  • Yield: Makes one serving

Some mugs don't microwave well because there is metal in their ceramic glaze. They'll work but they may get very hot. Best to use a plain old everyday un-fancy mug.

Ingredients

  • 1/4 cup flour (30 g)
  • 1/4 cup sugar (50 g)
  • 2 Tbsp (13 g) cocoa (natural, unsweetened)
  • Pinch of salt
  • Tiny pinch of cinnamon
  • 1/4 cup water (60 ml)
  • 2 Tbsp canola oil or vegetable oil (NOT extra virgin olive oil, it's too strongly flavored)
  • 1 to 2 drops vanilla extract
  • 1 small scoop of ice cream or 1 or 2 teaspoons heavy whipping cream to serve

Method

1 Place flour, sugar, cocoa, salt, and cinnamon in a microwave safe ceramic mug. Stir with a fork or spoon to mix well and break up any clumps.

2 Add the oil, water, and vanilla to the cup and stir until the mixture is smooth and there are no lumps.

3 Place in microwave and heat on high until the mixture is cooked through, about a 1 minute and 40 seconds for a 1000 watt microwave. You may have to experiment and adjust the time for less or more powerful microwaves. If you don't know the power level on your microwave, start with 60 seconds and increase until the brownie is done. It should still be moist when cooked through, not dry.

4 Let cool for a minute and serve with a scoop of vanilla ice cream or a teaspoon or two of whipping cream poured over.

    I read the comments while devouring my first attempt at this. Contrary to some of the reported results, this came out perfectly for me. (I made it exactly as written.) It’s probably a dangerous recipe for me to have on hand for these gray, chilly days when I tend to crave something warm and sweet!

    Is there any way to make it more of a moist, fudge, sweet brownie? It came out kind of dry and almost… dull. It wasn’t very sweet, and I didn’t get much of a chocolaty brownie feel… I may add some chocolate syrup or something of that sort, but the brownie itself was… disappointing. I was hoping to sink my teeth into a chocolaty brownie but it kind of tasted… Earthy? It was just off and kind of odd.

    This recipe turned out well for me are usually compilation of butter in oil and it was the perfect little brownie treat.

    I have tried many different mug cookie/brownie/cake recipes with little to no success, but as I’m bored on my day off I decided to try this one. This is it. I was really nervous about over cooking it, or potential ‘exploding’ but mine came out quite delicious and fudgy at 1:10. I may try cooking it a little bit longer next time but I’m talking like 10 seconds. This has made me so happy on this bleak day. Thank you.
