What You Need To Know

Below are the key details you need to master this recipe.

For a full set of steps and ingredients jump to the recipe card to make it now.

Mix the dry ingredients together first

It’s just easier to mix properly when you start with the dry, mix it up, then add the wet and form it into a batter.

Mix the batter thoroughly

This is an entire batch of brownies in under 10 minutes, don’t rush and mix the batter poorly you’ll end up with pockets of egg in the middle of your brownies. 

Choose the right low carb sweetener

There are many low carb sweeteners out there to choose from. Choose the one you are familiar with and that works for you. 

I always use either monk fruit or erythritol for keto desserts

Some other popular options are allulose, stevia and xylitol, although some of these may cause issues for some people. 

Note that not all sweeteners are the same and some are far sweeter than others. You may have to go by taste to make sure its sweet enough if you aren’t using monk fruit or erythritol. 

Use powdered sweetener 

Powdered sweetener, sometimes called confectioners erythritol, is a must for these brownies. 

Granular sweeteners does not distribute evenly and it wont taste as sweet. Powdering the sweetener solves that problem. 

You can either purchase powdered erythritol, or powder it yourself using a spice/coffee grinder. 

Choose the right chocolate chips

A few options available in the low carb chocolate department (imagine that was a real department somewhere!?) 

Dark bakers chocolate is very low carb, but a little on the bitter side. If you don’t like bitter chocolate choose something else. 

Hershey’s 70% Dark chocolate chip-its, are not as low in carbs, but taste more like chocolate you are used to so that trade off may be worth it to you. 

Dark chocolate melting wafers, and even a dark chocolate bar can be cut into chunks with a large knife for this brownie. 

Lindt excellence 90% dark chocolate would be a decedent and fairly low carb choice. 

There are also some chocolate chips that use low carb sweeteners like lily’s chocolate. 

Anything 85% dark chocolate or more should be low enough in cabs for this recipe. 

Use the chocolate that works for you and you like.

Choose the right container

This recipe is not unlike a mug brownie, in fact it is basically a mug brownie but a batch of them cooked in a different container. (you could use a mug though)

Choose a microwave safe container, glass is best like a Pyrex. 

For  this recipe I used a 3 cup (750 ml) rectangular Pyrex container that was the perfect size (these are great for leftovers too)

Use something similar or divide the batter up amongst many ramekins or mugs. 

The brownie will rise a lot while cooking, roughly double in size so make sure there is enough room in the container for it to expand or you will make a mess and your family will yell at you.

Don’t overcook it!

Every microwave is different so you may need to play around with it to find out how your microwave cooks these brownies. 

Start off cooking this for 2 1/2 to 3 minutes and then insert a test stick or toothpick to see if its ready. 

If the test stick pulls out clean when inserted the brownie is ready. 

If not, cook in additional 45 second increments until cooked properly. 

The brownie will cook a little bit even after you remove it from the microwave. 

If you like your brownie a little underdone then pull it out when the middle is still a bit soft and pudding like.

Let it cool and rest

The container will be HOT so use oven mitts and be careful when removing it from the microwave unless you don’t want fingerprints anymore. 

Let it rest and cool in the container for 3-5 minutes at least before cutting. 

You can of course stick a fork in it and eat it right out of the container like the champion you are…I’ve done it…many times.

Baking Instructions

Although this is intended to be a quick and easy microwave dessert for fighting those tough cravings on a low carb diet. 

These brownies can also be baked in the oven no problem just make sure you are using an oven safe dish!

Bake at 350°F [180°C] for 20-25 minutes until cooked through. 

Insert a test stick or a tooth pick into the center and if it pulls out clean its done!

    I made this with 3/4 cup ground pork rinds instead of the almond flour to further reduce the carbs. Not bad at all, quite good. I keep this recipe handy for when I’m having an intense sweet craving.
