Brownie in a Mug

Print

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

Print
  • 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 (50 g)
  • 1/4 cup sugar (70 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.

    This recipe was delish! I used dark cocoa powder, only about 1 tbs real sugar then a few packets of splenda (came to aporoximately 1/5 cup sugar mix) and followed the directions the rest of the way. Microwaved for 50 sec on high wattage microwave. The dollop of whipped cream on top made it! Thank you for the recipe. *As previously mentioned, the single serving is large* Thanks for the awesome post!

    Hi there! I looked at this recipe and it looks AMAZING!! I can’t wait to try this! The only problem I have is that I want to make this in a small ramekin that can hold 1/3 of a cup, and this recipe can’t be made in my ramekin. Do you mind giving me measurements to me so I can make this myself? If you can, thank you in advance!

    Great recipe! Thanks!!

    At first I was using lots of whipped cream with the brownie, but I figured out that it also tastes very yummy to just pour a little milk in the mug, after cooking. I use a little less sugar, too.

    This is the best brownie in a mug recipe I’ve found…and I’m a dessert in a mug junkie! A few tips: use a white or lite colored mug. I’ve found the best bake is with that. Also, stir the dry ingredients really really well to remove clumps of cocoa and flour! Definitely DON’T use olive oil…the taste is so incredibly overpowering.
    Lastly, this makes a large single serving. You can successfully half the recipe and put it in the micro for about 50 seconds at 1000 watt if you want a half of a serving. Pair this with ice cream and you’re in heaven!
