The best brownie mug cake

Single serving and easy to make, this decadent chocolate recipe can also be high protein, gluten free, sugar free, and vegan, with no eggs required.

And do you want to know the best part? Unlike many other chocolate brownie mug cake recipes, this one calls for absolutely no box brownie mix!

Feel free to add chocolate chips, or top with Coconut Ice Cream or Keto Ice Cream.

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.

For the 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.

For the fat: 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 haven’t tried a low fat version, many readers have written in to say they’ve had good results replacing the oil for applesauce or mashed banana. So you can try one of these fat free ideas if you want to experiment.

For a protein mug brownie: Simply substitute the tablespoon of cocoa powder with an equal amount of your favorite chocolate protein powder.

Flavor variations: Add a few drops of pure peppermint extract for a mint chocolate brownie in a mug.

Or add a drop or two of almond or maple extract or up to half a teaspoon of instant coffee powder.

You can even make a Nutella brownie mug cake by replacing the oil with a spoonful of 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 degrees Fahrenheit. 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?

Yield 1 mug brownie

Ingredients

  • 1 tbsp unsweetened cocoa powder
  • 2 tsp Dutch cocoa powder or additional unsweetened
  • 3 tbsp flour (spelt, white, or oat flour, or here’s a Keto Mug Cake Recipe)
  • 2 tbsp sugar or xylitol for sugar free
  • 1/4 tsp baking powder
  • 1/8 tsp salt
  • 1 tbsp oil or nut butter (some readers sub applesauce or banana)
  • 3 tbsp milk of choice
  • 1/2 tsp pure vanilla extract

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.

    What a great one serving brownie! Delicious and surprisingly easy! I used 2 Tbsp cocoa powder and added just a touch more sugar to balance. One minute in my 1200 watt microwave was all it needed. And I could kick the bowl since there were no raw eggs – bonus!!

    So I misread the recipe and used 3 Tablespoons total of cocoa powder and it was still good!!! Really fudgy flavor and a nice texture.

    I’ve always tried mug cakes and brownie recipes from TikTok and such and they always failed. They either tasted horrible or were a pain to clean. This one though… *Chef’s kiss*. Fudgy, moist, and does not rise out of the mug or burns at the edges.

    I didn’t add chocolate chips (I didn’t have them), and mine cooked completely in 1 minute in the microwave. Also, I mixed the batter in a bowl and greased my mug before pouring (more like putting) in the thick brownie batter. So the mug will be easier to clean.

    Thank you so much for this amazing recipe, it changed my life for the better 🙂

    my brother; a university student, was studying hard late tonight, and was craving brownies. seeing as it was late i didn’t want to make an entire dish, so this recipe was perfect, as it took literally two minutes to make, doesn’t make a mess, and is still as good as a home baked brownie. will be making again!! 🙂

    I never comment on food blogs, but I make this recipe every few days when I’m craving something sweet, it’s the best mug cake I’ve tried. I add chocolate chips and substitute 2 tbsp sugar for 1 tbsp monkfruit and another tbsp vanilla cake protein powder. I also use whole wheat flour with peanut butter, which results in 20 grams of protein packed into a delicious personal sized brownie. What’s not to love?
