This low carb keto mug brownie is a rich and decadent treat that can be ready in a matter of minutes! It’s the perfect single-serving dessert to satisfy your chocolate craving.
Since switching to a low carb way of eating, I’ve noticed that I don’t really crave sweets very often. But every now and again, the chocolate craving strikes.
I have nearly 200 dessert recipes on my site, so there is always something delicious to make. For example, my keto zucchini brownies can easily satisfy a crowd!
When to make the recipe
With most dessert recipes, you end up with leftovers. And I don’t always want to have that temptation sitting around the house.
That’s when this single-serve keto mug brownie is absolutely perfect!
The whole recipe only requires 7 ingredients and can be ready in 2-3 minutes. How easy does that sound? Plus, it’s made with coconut flour, so it’s totally nut free as well as gluten free.
You can also control the texture of your mug brownie based on how long you microwave it. Undercook for a gooey brownie, or cook the full 90 seconds for a cake-like texture. It’s completely up to you!
The next time you’re craving chocolate and don’t want to spend time in the kitchen making a whole recipe, you have to try this keto brownie in a mug.
Step by step instructions
Ready to see how easy it is to whip up a rich, decadent, keto friendly dessert?
- In a mug or ramekin, melt coconut oil and sweetener in the microwave. It will only take about 15 seconds.
- Stir in the vanilla extract and the egg.
- Mix in cocoa powder, coconut flour, and baking powder.
- Add heavy cream.
- Stir until a thick brownie batter forms.
- Microwave anywhere from 30-90 seconds to reach your desired texture.
That’s it! The next time you find yourself craving something sweet and chocolate, you’re only 5 steps away from this delicious low carb mug brownie.
Note on cooking time
When microwaving, keep in mind that a shorter cooking time will give you a fudgy brownie while a longer cooking time will make the texture more cake-like.
I recommend starting with 45 seconds, then checking the center. The cook time will also depend on the keto brownie mug or ramekin you’re using.
How to serve it
I always enjoy my mug brownie warm with a little bit of homemade whipped cream on top. It’s so good! I make mine using a whipped cream dispenser.
You could also top your freshly baked brownie with a little keto vanilla ice cream for an extra delicious treat. The cold ice cream will melt into the hot brownie for an incredibly satisfying dessert.
If you like your brownies with walnuts, feel free to chop a few and add them on top! You could even pan toast them for a few minutes to deepen their flavor before adding them to the brownie.
If you’re going to treat yourself, you may as well do it right!
Despite being made in a ramekin, this keto brownie actually turns out quite large! I think it’s perfect for 2 servings.
This means you can share it with someone special, or save the other half for tomorrow’s dessert.
Or, if it fits your macros, you can always treat yourself to the whole thing. The full recipe is 250 calories with 14 grams of total carbohydrates and 6 grams of fiber. This leaves you with 8 net carbs for the whole brownie.
It’s certainly an indulgence, but it’s not overboard to enjoy all to yourself!
If you decide to save half, simply store in an airtight container in the refrigerator.

My husband asked for this mug cake for a treat. He really enjoyed it. My daughter liked it a lot too. Topped with keto whipped cream. It’s a keeper recipe. Thank you for sharing this.
Absolutely delicious, easy to make, and helps me stay on track!
Too much chocolate for me.
Fair enough, I understand that coconut flour is super absorbent and that it is your recipe but, I still think the proportion of BP to flour incorrect.
I made this today with the changes (I mentioned) in flour to BP.
The results were impressive but, sadly I didn't pick up on the 2 TABLESPOONS of cocoa powder which made the brownie very bitter and inedible.
"2 tablespoons unsweetened cocoa powder
2 teaspoons coconut flour
½ teaspoon baking powder"
I think the Gremlins took over and it should read
2 teaspoons unsweetened cocoa powder
2 Tablespoons coconut flour
½ teaspoon baking powder
I intend making these again (correcting ingredient amounts I mentioned) as the recipe has potential for being absolutely divine.
All the best.
I have made it the way it's listed for years without an issue. A serving of cocoa powder is 1 tablespoon so 2 teaspoons might not be enough. Some cocoa powder is more bitter than others.
"2 teaspoons coconut flour"
"½ teaspoon baking powder"
I think this is a typo?
Should the recipe not be 2 TABLESPOONS coconut flour?
(BP ratio to flour is totally disproportionate as it stands)
I am about to make this with the adjustment suggested but, cannot rate until then. Looking forward to your response 🙂
You actually need only about a fourth to a third of coconut flour compared to all-purpose flour and almond flour. It soaks up the liquid and egg to expand so you don't need as much of it.
I actually did this by mistake (I used two tablespoons, instead of teaspoon), but to fix it I had to double the egg, the baking soda, the sugar and the time... as the author said you don't need much coconut flour. It turned out quite well after the adjustment 🙂
If I "undercooked" this brownie, would I have a "molton" brownie?
I haven't tried it with this recipe, but it should work.
I'm afraid this tastes bitter. I've seen recipes with half the amount of baking soda for only 12 brownies, so that's probably the problem. I didn't get much of a chocolate taste despite all the cocoa; maybe more coconut oil is needed to "lubricate" the flavor.
You could try more vanilla extract and reduce the cocoa a little. A bit more sweetener may work too.
