The gooey brownie in a mug was adapted from my healthy chocolate mug cake, which is one of the reader favorite recipes on my site.
To turn it into a single serving brownie, I played around with the ingredient ratios and also added some Dutch cocoa to give it that ultra rich, deep and chocolatey classic brownie flavor.

Brownie mug cake ingredients
Cocoa powder – The recipe calls for both regular unsweetened cocoa powder or cacao powder and Dutch process cocoa powder.
If you can only find regular cocoa, it still works without Dutch. The brownie mug cake will just not have as much of a rich traditional brownie flavor.
What type of flour? You can use white all purpose flour, whole grain spelt flour, or oat flour. There is also a keto option included in the recipe.
I have not tried almond flour, coconut flour, or whole wheat flour here and therefore cannot recommend those.
Oil or applesauce – The video uses coconut oil, but you can substitute any neutral oil or your favorite healthy nut butter of choice, such as peanut butter or almond butter.
While I prefer using oil instead of a low fat version, many readers have written in to say they love the results when replacing the fat for applesauce or mashed banana. So you can try one of these fat free ideas if you want to experiment.
Flavor variations
Protein Mug Brownie. Simply substitute the tablespoon of cocoa powder with an equal amount of your favorite chocolate protein powder.
Mint Chocolate. Add a few drops of pure peppermint extract (up to 1/4 teaspoon) along with the wet ingredients.
Mocha Brownie. Stir half a teaspoon of instant coffee powder in with the cocoa powder. Or use espresso in place of the milk.
Nutella Mug Brownie. Replace all of the oil with a heaping spoonful of jarred chocolate hazelnut butter or this Homemade Nutella Recipe.
How to make the recipe
To whip up the chocolate dessert, simply stir together the cocoa powder, flour, sugar or sugar free sweetener, baking powder, salt, oil or nut butter, milk of choice, and pure vanilla extract in a in a coffee mug or heat safe dish.
The brownie can be made in a microwave or a conventional oven. Be sure to grease the mug first if you want to remove the cake before eating it.
If you are baking the mug brownie in an oven, preheat it to 350° Fahrenheit or 176 °Celsius. Once it reaches the set temperature, bake the mug cake dessert for fourteen minutes on the center rack of the oven, then let it cool.
Or if you prefer a microwave brownie, place the dish or coffee cup in your microwave and cook until done. Time will depend on your microwave’s wattage.
I cooked my fudgy mug brownie for a minute, followed by two ten-second increments, so the mug dessert will be ready in about eighty or ninety seconds total.
Store leftovers covered in the refrigerator for up to three days.
Wait, what leftovers?
Here’s a vanilla version: Vanilla Mug Cake
Brownie In A Mug
Ingredients
- 1 tbsp unsweetened cocoa powder (5g)
- 2 tsp Dutch cocoa powder or additional unsweetened cocoa powder (4g)
- 3 tbsp flour (22g) (spelt, white, or oat flour, or here’s a Keto Mug Cake Recipe)
- 2 tbsp sugar or xylitol for sugar free (24g)
- 1/4 tsp baking powder
- 1/8 tsp salt
- 1 tbsp oil or nut butter (12g) (some readers sub applesauce or banana)
- 3 tbsp milk of choice (45g)
- 1/2 tsp pure vanilla extract (3g)
Instructions
- *If you want to remove the brownie mug cake before eating it, be sure to grease the mug before starting. If you can’t find Dutch cocoa, subbing additional regular will still work; it will just have less of a brownie flavor. I haven’t tried subbing applesauce or banana for the fat and therefore can’t vouch for the taste of that substitution.If baking the brownie in a mug, preheat your oven to 350 F. Combine all ingredients in a mug or 1-cup dish (or two 1/2-cup dishes). Either bake around 14 minutes, OR microwave until set. Microwave times will vary depending on wattage and if using one or two dishes – I cooked mine for 1 minute, followed by two 10-second increments.

So good! I have tried several recipes and Katie has the best! True chocoholic here.
I used all purpose flour, measured everything carefully. It was moist but cooked at a minute and a half. Like another reader, I think it was a bit cake-like. I might try taking the baking powder down a little next time. So glad you shared this! I’m sending a link to my friend.
This is sooooo good!!!! I love it!
Really amazing recipe! 😁 Put mine in for 1min 30sec. Delicious 😋
so yummy tastes like real cake! be careful though its really hot when you take it out lol
Has anyone tried it with almond flour?
You can! https://lett-trim.today/keto-mug-cake-recipe/%3C/a%3E%3C/p%3E
Straight-up delicious. I used a combination of oat and white flours. This is a super awesome recipe if you want a warm, chocolaty dessert but don’t have the time/energy to bake. I have made this many times and will make it again.
I subbed oil for banana and topped it with ice cream, so good!
Subbed peanut butter for the oil. Not quite a “brownie” but definitely satisfied my sweet tooth. I didn’t have ice cream, but that would have made it much better!
I made this tonight with coconut oil, monk sweetener, vegan chocolate chips, and almond milk. It was so so good! Microwaved for 1 min, then another two 10 second increments as suggested in the recipe. Just like you said, and voila. Perfect. So easy and delicious, great to curb the chocolate craving while sitting on the couch watching TV. Dangerous…
Thank you so much for making it 🙂
I’ve made this brownie in a mug several times now. It always tastes great and is so quick and easy. Mine seems to bake more like cake than a brownie, but I still love it. Thanks
Seriously 5 star! This hit the spot. Thank you, Katie!
Thank you so so much for making it 🙂
Yup I liked this:) it was very good:). I added some chocolate and expresso chips. Mmmmmmm
At 65 years old I’m still a major chocoholic at times! Your recipes are AMAZING Katie! Thank You so much for making this old woman’s day as usual! You never fail!
I’d never made a brownie in a mug before so I was a bit skeptical, but this is amazing. Using date sugar, whole spelt flour and almond butter makes this a nutritious dessert (until I added the vegan vanilla ice cream). I love that I don’t have an entire pan of brownies to tempt me and I can make a single serving whenever I want. This recipe and concept has changed my life for the better. 😀
❤❤
I loved this brownie in a mug. I added chocolate chips to mine. It came out perfectly!
For those who were crabbing about it taking too long to put the ingredients together, do us all a favor and go out for dessert.
