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 deep and chocolatey classic brownie flavor.

Brownie mug cake ingredients
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 at your own risk.
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 14 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 10 second increments, so the dessert will be ready in about 80 or 90 seconds total.
Store leftovers covered in the refrigerator for up to three days. Wait, what leftovers?
Here’s a vanilla version: Vanilla Mug Cake
Above – watch the video how to make a brownie in a mug
Brownie In A Mug
- 1 tbsp unsweetened cocoa powder
- 2 tsp dutch cocoa, or additional regular
- 3 tbsp spelt, white, or oat flour (Here’s a Keto Mug Cake Recipe)
- 2 tbsp sugar, or sub erythritol if desired
- scant 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
- Notes: If you want to remove the 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, preheat 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.
