This is the recipe for brownies you've been waiting for. Rich brownies topped with coffee buttercream AND caramel sauce. They are so decadent just a few bites is all you need for your caramel macchiato craving.
In this free 5-day email series learn all my tips for incorporating a low-carb lifestyle into the life of your family.
This is one of the most indulgent recipes I've ever made. Chocolate keto brownies with coffee buttercream icing AND caramel sauce? Oh yes. I had no problem taste testing these last Friday after a long week.
How to Make Brownies
There are many variations on a traditional brownie recipe. To start you need either cocoa powder, melted chocolate, or both. This keto brownie recipe calls for cocoa powder. This is based on Hannah's Fabulous Low Carb Brownie Recipe. Hannah's brownies were one of the first guest posts I've featured and are still one of the most popular.
For keto brownies, you need chocolate, a sweetener, most of the time you need a flour, and then a binding agent like eggs. The ingredients are simple and if you've done any low carb baking you probably have most of them in your pantry already.
I'm a dump and mix kind of girl. My favorite recipes are ones that you add everything at once then mix it up. Simple. Fast. Done. With 5 kids in the house using every cup and plate in my cabinets I try to keep the dishes I use to a minimum.
Mix up the brownie batter, put it in an 8 x 8 baking dish and bake. The chocolate chips are optional in this recipes because once you cover the keto brownies with coffee buttercream and caramel sauce you really don't need them.
How to make Buttercream
Buttercream is my favorite type of frosting hands down. It is SO easy to make and it's just as easy to make it sugar-free as to make it with regular sugar. To make a perfect buttercream all you need to do it whip up some butter and add powdered sweetener. In almost all of my recipes, I just use my sweetener blend of xylitol, erythritol, and stevia. Buttercream is one recipe that I do recommend using a powdered sweetener such as Swerve. You can grind your own sweetener at home but it's hard to get it as powdery as professionally ground sweeteners.
How to Make Caramel Sauce
Making caramel is one of the trickiest techniques for a home cook. It can be hard to tell when it is done. Having made caramel dozens and dozens of time over the last few years here are my tips:
1. Start slow. It is easier to turn up the heat for a caramel that is taking too long than to try and save a burned caramel.
2. Whisk, whisk, whisk. I've made caramel enough that I'm confident leaving it unattended in the early cooking stages but if you are new to caramel making stay at the stove and watch it. The ingredients for a sugar-free caramel are not something you want to throw away.
3. Go by smell and color. I know my caramel is done when it is a deep golden brown, smells very fragrant, AND has some darker bits at the bottom of the pot. As soon as this happens, remove the pot from the heat immediately and whisk furiously to reduce the temperature. Some of my caramel recipes call for some extra butter or cream added at the end to reduce the temperature quickly but that isn't always necessary.
I love swirling pretty designs in icing. To make this one on my Caramel Macchiato Keto Brownies just alternate dragging the knife back in forth horizontally and then do the same thing vertically.
After my first go at this recipe, I cut the amount of buttercream frosting in half. They came out too sweet. But if you have a real sweet tooth and want an over the top indulgent dessert go ahead and double the buttercream recipe listed!
Leftover Brownies Truffles
Any time I mention my leftover brownie truffles I get odd looks. Leftover brownies? Who has those? Maybe I am the only one but if you are baking just for 1 or 2 sometimes you can be left with half a tray of brownies that you are tired of eating for dessert after 6 nights in a row. You could freeze them. Or you can make truffles. This was one of the easiest recipes I've made Fudge Brownie Truffles from because the topping has so much moisture you don't need to do anything else. Smush them, mix well until you have a smooth dough, shape into balls and either dust with cocoa or dip in melted chocolate. Then enjoy the best mocha truffles you've ever tasted.

I followed the recipe to a T, and love all that you post. Brownies recipe and the butter cream frosting are definitely winners. HOWEVER, the caramel sauce crystalized into a sheet when I poured it over the frosting. I ended up letting it completely harden, then removed it in chunks and tossed it. I will make the recipe again, but skip the caramel sauce, unless you can recommend a good quality keto version I can buy pre-made. Thanks for all your fabulous recipes, Taryn. I'm a fan!
Taryn says
Thanks for the feedback! I'd appreciate if you can also leave reviews on the fabulous recipes and not just the ones that don't work for you 😉 As far as caramel sauce I like the sauces from ChocZero.
Kim says
What is the measurement to sub THM Baking Blend and what do I omit?
Taryn says
2/3 cup in place of the almond and coconut flours.
Wafaa says
Hello
What do you in your recipe half and half please?
Taryn says
Half and half is common in the United States. It is half milk and half cream. You can use a light cream instead.
Lynn Robinson says
Can you use THM gentle sweet in the frosting?
Taryn says
No, these would be much too sweet. You need the bulk of the sweetener to make a true icing consistency. You could just grind xylitol or erythritol to a powder and use that.
Cheryl says
I needed to at least double the buttercream to come even close to having enough to cover the chocolate cake.
Taryn says
Hi Cheryl, that shouldn't be the case. Did you use an 8x8 pan? Did you use swerve? This makes 16 tablespoons of icing as it is written. That is plenty to cover the brownies.
Cheryl says
I am so embarrassed and I posted on your Facebook page. I FORGOT TO ADD THE CREAM CHEESE. I had softened it in micro and found it later. I did not know how to let you know. I made another batch and it was perfect. Please feel free to delete this and Ibwill add a 5 star. I ms so sorry. 😢
Taryn says
That's ok! It happens to all of us at some point.
Nancy Dibler says
Caramel sauce came out in clumps. Cooked to long?
Taryn says
Which sweetener did you use? Did it taste burned?
Nancy Dibler says
Did not taste burned . But did not drip like yours. It ate well. Family ate it. One piece left.
Nancy Dibler says
I used the sweet trimmed mama sweetener
Nancy says
What is your opinion of Monkfruit
Taryn says
I like monk fruit. If you decide to use it you will need more. It is 1:1 for sugar. Gentle Sweet is 2:1.
Abigail says
Do these freeze well?
Taryn says
Yes. The caramel sauce will crystallize but they are still delicious. It's just more like a toffee than a caramel at that point.
Christina says
I’ve seen you talk about using ground raw sunflower seeds as a sub for almond flour to make something nut free. Would that work in this recipe?
Taryn says
Yes, I think so. I haven't tested it in every recipe yet. If you try please lmk how they turn out!
Aimee Shugarman says
This is wonderful!!!! So much flavor in every bite.
Tayler Ross says
My favorite coffee shop drink turned into a delicious treat! I love this!
Kelly Anderson says
The sweetener in the buttercream came out grainy.
Taryn says
Did you use powdered erythritol, like Swerve?
