We knew that this keto macadamia brittle was destined to be a holiday season classic around here at first bite. It’s a taste combination that is pure magic — keto toffee, roasted macadamias, and ultra dark chocolate.
A Keto Classic Christmas Cookie 🎄🍪
The new status of “classic” in our house ultimately comes down to one thing — replay value. Like all of you, we are quite busy and try to work from our pantry rather than make unplanned one-off trips to the grocery store. This Keto Macadamia Brittle uses only a few ingredients that we always have around — butter, erythritol, macadamias, vanilla, and super dark chocolate. 🍫 This makes it an easy one to reach for to make consistently year after year.
This recipe’s simplicity also makes it incredibly kid-friendly, so it is fun for the whole family 👪 around the holidays. Our little ones love to watch the sweetener transform and caramelize. With appropriate supervision they can stir in the nuts and help to pour out the mix. Then the magical hardening occurs, after which they love breaking the brittle up and dipping it in dark chocolate.
Costco “Blue Bag” Macadamias’ Cult Following
Like many of you who have confessed this to us on Low Carb Papa’s Facebook page, we are completely addicted to the Royal Hawaiian Salted Macadamia Nuts that are sold in our Costco off and on in the powder blue bags. I am being generous when I say “on and off”, as it has been mostly off recently. Their scarcity is probably the only thing preventing my from totally blowing my fat macro on them, so I suppose I should be somewhat thankful.
Recently my Costco has started putting out a pallet of undersized macadamia halves by the same grower (Royal Hawaiian) in slightly different packaging. I grabbed some packs as a consolation prize in my quest to procure a new supply of the much-desired “blue bags”. 🥈
As I dove into them on the way home, getting macadamia nut oil and salt all over my steering wheel, I thought a little about opportunities their size might present. They are almost the size of large peanuts 🥜, you know?
So, peanuts. Peanuts, peanuts, peanuts. Peanut… brittle? Keto macadamia brittle? Dipped in dark chocolate, because why the hell not?
Using Erythritol Sweetener In Keto Macadamia Brittle
Credit really has to be given here to Carolyn Ketchum of All Day I Dream About Food whose process for making erythritol-based pecan brittle has been adapted to use macadamias here. (Spoiler alert: It behaves mostly the same as sugar. Erythritol is terrific stuff, right?)
It also boggles the mind a little she was doing this back in 2010. You know what I was doing in 2010 while she was experimenting with erythritol brittle? Eating garbage food that was killing me. This is a woman who has a wealth of experience and really knows her stuff — which is why it’s positively criminal she did not have cookbooks 📚👩🍳 published until relatively recently. I can wholeheartedly recommend The Everyday Ketogenic Kitchen, Easy Keto Dinners, and Easy Keto Desserts. You can also read my review of The Everyday Ketogenic Kitchen here. (Disclosure: I received evaluation copies of all three books, but was not otherwise compensated.)

Dark Chocolate Keto Macadamia Brittle 🍫🍪
We knew that this keto macadamia brittle was destined to be a classic around here at first bite. It's a taste combination that is pure holiday season magic -- keto toffee, roasted macadamias, and ultra dark chocolate.
Chop the butter into small pieces and melt in a saucepan.
Add the erythritol and bring to a boil, stirring to dissolve it completely.
The simmering will slow as the water boils off and the mixture will thicken slightly and start to caramelize and smell amazing. If you are using a candy thermometer, which I recommend, the mixture will be a little over 300 degrees F. Remove from the heat at this point.
Pour out the mixture onto the sheet pan and let cool completely. You can place it into the fridge to speed this process up.
Once the mix is cool, break into approximately 16 pieces and set aside.
This recipe produces candy that lives up to its "brittle" moniker. It will not be as hard as its full sugar counterpart. I would not advise using a cooling rack for draining excess chocolate from the candy after dipping it in dark chocolate. It will be very difficult to remove from the rack when cool without destroying it.
