I’ve been looking for some different ways to use the Homemade Macadamia Nut Butter that I made the other day. I’ve not had custard in a long time, but for some odd reason it popped into my head and I got a craving. I set out to make a recipe that can stand up to low carb, but still taste great.
I went for a texture that custard should be when baked – some egginess, but a velvety soft texture. As you chew, the notes from the vanilla, egg, coconut milk, and then macadamia nut butter come through, giving a great balanced flavor to the custard.
I prefer using coconut milk for this recipe because it is quite thick and really helps for the mixture to become creamy and decadent. The coconut flavors play off of the macadamia nut butter and creates a rich and creamy flavor that I haven’t tasted anywhere else.
The macros are near perfect on it too, coming in at 75% fats, 18% protein and 6% carbs. If you have a sweet tooth and were ever worried about baking things that had too many carbs – this is your ticket out of that phase!
I really wish I had a blowtorch so that I could have brûlée’d the top of this thing. I’ve had the idea in my mind to create some keto-friendly crème brûlée. Actually, a crème brûlée sounds amazing, but I’m not too sure how erythritol would stand up to the heat.
If you have a blow torch and you’re willing to try this – I’d love to hear the results (and pictures if you can)! Let me know how if you made this in the comments below 🙂

Hi Craig,
Thanks for sharing this yesterday in the LCHF FB Group.
It looked so delicious, I’m having them in the oven as I write this.
I used almond paste (since I did not have macademias and left the stevia out, because it was already very sweet for my taste.
I’m hoping they come out as good as they look :).
Hey,
No problem. I think they should taste pretty nice with some almond paste in. How’d they come out? 🙂
hey craig,
what’s the size of the servings listed up on the chart. I’m cross referencing this recipe with the fat fasting page and it seems like you could get away with eating this 4 times a day for a few days and still reap the benefits of the fat fast. Is that correct?
Mike, the serving size is a custard from the ramekin. The 4 ramekins that are shown, the serving is 1 of those. You could use this for a fat fast if you want 🙂
This recipe is everything! I have made it three times now. Simply fantastic!
Thanks Kimberly! I think some people are afraid to try it, but they need to 🙂
Wow I can’t wait to try your recipes! One question though… I don’t have any erythritol. Can I omit it or maybe replace it? Thank you for sharing all these fabulous recipes, you can’t imagine how grateful I am . Olivia
Olivia,
I highly suggest grabbing some off of Amazon. 1 lb. of the stuff is around 19 bucks and it’ll last you a long time. It’s worth it, to me at least, and helps me sweeten things without adding any extra blood sugar spikes. If you want, you can replace it with pretty much any sweetener you have on hand (ratios, though, I’m not sure of). Erythritol is about 70% as sweet as sugar if that helps.
My best and good luck with the recipes!
I just made this recipe, and it was super yummy. I don’t do dairy so I subbed coconut milk (the thickest part). Also I don’t have erythritol yet so subbed xylitol. I also made my own macadamia nut butter for the first time. Great success! Thanks for the great recipe. 🙂
I love the Macadamia Nut butter. Whenever I make it, I have to put it somewhere I forget about it otherwise it just ends up on a spoon and in my mouth 😛 Glad you liked it!
Why “almost”?
Per serving, the macadamia nut & coconut custard has: 275 Calories, 26.2g Fats, 2.5g Carbs, and 6.2g Protein. It’s almost a perfect keto treat!
Almost because it was a slight bit off on the carb ratio, but it’s very easy to fit into your macros.
This looks amazing! I had one question – I can’t seem to tolerate any sugar alcohol, regardless of the type. Is the erythritol integral to the texture, you think? Or could I do pure liquid stevia without a problem?
Thank you for your time 😉
