Pretty much everyone loves chocolate, right? You do, too, which is why you’re here.

That’s why this single serving microwave baked birthday cake is so popular. And why grabbing a few Lily’s bars at your local grocery store is always a good idea.

But sometimes you just need a perfectly decadent, gooey brownie to satisfy your chocolate craving. If you have the time and someone to share it with, make up a batch of these low carb zucchini brownies. But what if you don’t?

After all, sometimes you just want a chocolatey treat in a
“now” kind of a way…and you don’t want to have to worry about sharing…or having sugar. That’s how this low carb one minute chocolate brownie you can make in the microwave came to be.

You can find a gluten free, keto friendly brownies recipe that will feed a crowd…but when you don’t want to eat the whole pan and you’re home alone, this single serve keto brownie in a mug is the best recipe to make.

Ingredients For Your Gluten Free Keto Brownie Mug Recipe

What do you need to make this simple keto brownie in a mug recipe? Only 7 ingredients!

Coconut oil
Low Carb Sweetener
Vanilla extract
Egg
Unsweetened cocoa powder
Coconut flour
Baking powder
Heavy cream

As you can see, there’s no almond flour or almond meal in this low carb brownie, which makes it perfect for those who want a nut free recipe. And because the ‘flours’ used are coconut and cocoa powder, it’s completely gluten free.

How To Make A Single Serve 1-Minute Keto Mug Brownie

Making this quick little low carb one minute chocolate brownie in a mug cake is very simple.

To start out, melt a little coconut oil in your mug. It only takes about 15 seconds or less for the coconut oil to melt into a liquid.

Then add in granular sweetener, vanilla extract, and an egg.

Then, you add in the coconut flour, cocoa powder, and baking powder to make the brownie batter thick.

I found that it works best if you combine the dry ingredients together in a separate cup first. However, if you’re like some people (ahem), and you don’t want to have to wash that extra cup, you can just mix them all in the same continer.

To thin the batter and provide more fat and flavor, heavy cream is mixed in too.

The batter should be about the same consistency as cake batter after mixing in the cream. Then it’s just microwaved on high for 30 to 90 seconds. You can bake it in an oven or air fryer too if you don’t want to use a microwave. Just bake until the desire doneness at 350°F.

If you like a really moist fudgy brownie, you’ll want to undercook it just a bit…and maybe add some sugar free chocolate chips to the batter.

Fully cooking the one minute chocolate brownie batter in the microwave for about a minute or more results in more of a mug cake texture, so it’s all up to you. What’s your favorite way to indulge in an easy brownie?

Serving And Storing Your 1-Minute Brownie In A Mug

This ends up being a rather large one minute keto brownie in a mug, perfect to share. It’s just a tad too much for one serving if you’re having it with a meal (but you could always have it as a meal!).

If you’re not wanting to share (and who would blame you?), you can easily eat half and save the other half for later, too. And just think of the possibilities!

You can enjoy this one minute chocolate brownie plain right out of the microwave (mmm, hot brownie!) and simply let the half you don’t eat cool completely and store it in an airtight container.

Or, if you’d like to treat yourself or you want to have this as an extra special dessert, you can top your freshly baked hot brownie with a little sugar free whipped cream from your whipped cream dispenser. And maybe add some sugar free vanilla ice cream, too.

This easy brownie in a mug cake is a low carb treat that you can easily whip up any time a snack craving hits you; that’s one of the best things about recipes like this.

1-minute mug cakes are a great way to stay on track even when the cravings hit. Mini dairy free waffles are another great way to make fast personal sized cakes.

Which Sweetener Is Best For This Low Carb Recipe?

I originally made the recipe with a Sukrin Fiber Syrup Gold and no egg. The net carbs are about same regardless of whether you use a fiber syrup or erythritol based granular sweetener, so that’s good news.

Some people have reported that they are sensitive to the carbs in the Isomaltooligosaccharides (IMO) based fiber syrups. If you’re concerned about this you can just use a granulated sweetener. Also, you may want to test your blood glucose levels to make sure this sweetener doesn’t cause insulin spikes for you.

Even though these fiber carbs are said to be negligible, I don’t like taking in more than I have to. That’s why swapping out the granulated sweetener can be a good choice.
