It’s quickly become one of my go-to keto coffee drinks at home, and if you’re into low carb coffee recipes that don’t taste like cardboard or sadness, this one’s going to be your new favorite.

So whether you’re already deep into your keto groove or just poking around for keto iced coffee drinks that don’t cost a fortune like some keto Starbucks drinks at home, hang tight. We’re keeping it simple, affordable, and full of flavor.

You won’t need any weird ingredients or fancy gadgets. Just a few pantry basics, a blender, and ten minutes of your morning.

Where This Came Mac Nut Coffee From?

Let me tell you what kicked this off. I was on the Big Island, early morning, sitting on a porch with nothing but a mug of hot coffee and the sound of roosters off in the distance. That coffee had macadamia nut milk in it—creamy, slightly sweet, and nutty without overpowering the coffee. I knew I had to bring that flavor back into my routine.

But I also didn’t want to ditch my keto habits. That meant no sugar bombs, no syrup overload, just a smooth keto latte recipe that worked hot or iced. I started experimenting with mac nut milk, MCT oil, and low carb sweeteners, and after about five flops and one disaster that tasted like oily soup, this version came out perfect.

Ingredients You’ll Need

Here’s what you’ll want to gather. Nothing too fancy, I promise:

• Freshly brewed coffee (about 1 to 1½ cups, depending how strong you like it)
• Unsweetened macadamia nut milk (½ cup) — look for brands with no added sugar
• 1 tablespoon MCT oil or coconut oil
• ½ tablespoon grass-fed butter or ghee
• Low carb sweetener to taste (monk fruit or erythritol are good picks)
• Pinch of sea salt (don’t skip this)
• Optional: A dash of cinnamon or a splash of vanilla extract

If you like keto iced coffee drinks, you’ll also want to have some ice ready and maybe a splash of heavy cream to swirl in for extra richness.

How To Make Hawaiian Keto Mac Nut Coffee (Hot or Iced)

Whether you’re craving something cozy and warm or something cool and refreshing, this Hawaiian keto mac nut coffee has you covered. You don’t need fancy equipment or barista skills, just a blender, some solid ingredients, and a few minutes.

Hot Version: The Creamy Island Morning Ritual

Step 1: Brew the Coffee

Start with your favorite coffee. Drip machine, French press, pour-over—it all works. Aim for about 1 to 1½ cups. Want it stronger? Use a darker roast or an extra scoop of grounds.

Step 2: Warm the Mac Nut Milk

Pour about ½ cup of unsweetened macadamia nut milk into a small pot or microwave-safe cup. Heat it gently until it’s warm but not boiling. You just want to take the chill off so it blends smoother with the fats.

Step 3: Add Everything to the Blender

Into your blender, toss in:

• Your brewed coffee
• The warm macadamia nut milk
• 1 tbsp MCT oil (or coconut oil)
• ½ tbsp grass-fed butter (or ghee)
• Your favorite keto-friendly sweetener (start with 1 tsp and adjust to taste)
• A tiny pinch of sea salt (brings out the nutty flavor)

Optional extras: A dash of ground cinnamon or a drop of pure vanilla extract if you want a little cozy twist.

Step 4: Blend Until Frothy

Blend on high for about 20–30 seconds. You want a creamy, frothy texture, like a proper latte. The fats should be completely blended in—no oil slicks on top. It’ll smell amazing.

Step 5: Pour and Sip

Pour into your favorite mug. If you added cinnamon or vanilla, take a second to enjoy the aroma. That’s it—you’re ready to sip your way to a better morning.

Iced Version: The Cool, Creamy Copycat Starbucks Move

Step 1: Chill Your Coffee or Use Cold Brew

This is the part where a little planning pays off. Brew your coffee ahead of time and keep it in the fridge, or use ready-made cold brew. You’ll want about 1 to 1½ cups. Stronger is better since ice waters things down a bit.

Step 2: Keep the Mac Nut Milk Cold

No need to warm anything here. Use that cold macadamia nut milk straight from the fridge—½ cup is just right.

Step 3: Blend It Cold

Into your blender, add:

• Chilled coffee or cold brew
• Cold macadamia nut milk
• 1 tbsp MCT oil or coconut oil
• ½ tbsp butter or ghee (it blends cold just fine with a strong enough blender)
• Your favorite low carb sweetener
• Pinch of sea salt

Optional flair: Vanilla extract, a little cinnamon, or even a small scoop of unsweetened cocoa powder for a mocha twist.

Blend for 20–30 seconds until everything is creamy and smooth. It’ll look a little like a milkshake, but feel way better.

Step 4: Pour Over Ice Like a Pro

Grab a tall glass, fill it halfway with ice, and pour your blended keto coffee right over it. Want it to look fancy (and hit those Pinterest vibes)? Drizzle a tablespoon of heavy cream on top and let it swirl down through the coffee. It’s that little extra that makes it feel like a fancy café drink—without the price tag or the carbs.

This method keeps it quick, clean, and delicious—no syrupy mess, no mystery ingredients. Whether you’re sipping it warm in the morning or chilling out with the iced version on a hot afternoon, this drink fits right into your keto diet drink ideas list and can slide easily into your healthy drink recipes collection.

Why This  Hawaiian Keto Mac Nut Coffee Works on Keto

This isn’t just tasty, it also checks all the boxes if you’re looking for solid keto coffee ideas that keep your macros clean:

• No sugar
• Healthy fats from MCT oil and butter
• Super low carb (we’re talking under 2g net carbs depending on your sweetener)
• No hidden junk — just real ingredients

Macadamia nuts are naturally high in fat and low in carbs, which makes mac nut milk a solid pick for low carb coffee lovers who want something lighter than heavy cream but still keto-approved.

Make It Your Way

This recipe is flexible. Like, real flexible. I’ve messed with it so many times, and every version works in its own way.

If You Like it Sweeter:

Add a few drops of liquid monk fruit or a bit more erythritol. Just start small—those sweeteners pack a punch.

More Creamy?

Use a bit of heavy cream or even a tablespoon of cream cheese blended in. Yeah, cream cheese. It sounds weird, but it makes the drink taste like a cheesecake latte.

Need It Stronger?

Brew your coffee double strength. Boom. You’ve got yourself a bold low carb coffee that’ll keep you going through the chaos of Monday mornings.

Storage Tips and Lazy Hacks

Let’s be honest. Sometimes you just don’t want to haul out the blender at 6AM. So here’s what I do:

• Prep a batch of coffee and keep it in the fridge. That way you can make the iced version on demand.
• Pre-mix the fats. Mix your MCT oil, butter, and sweetener in a jar. Scoop a tablespoon out each morning and toss it in the blender.
• Use a milk frother. If the blender’s too loud or annoying to clean, a frother works in a pinch. Not quite as creamy, but still solid.

Where It Fits Into Your Day

This isn’t just a drink—it’s practically breakfast. With the healthy fats and zero sugar crash, it keeps you full longer than regular coffee. You can pair it with a quick egg bite or low carb muffin, or just sip it solo if you’re intermittent fasting. It’s one of those keto coffee drinks that actually helps keep you on track without making you feel like you’re missing out.

Why You’ll Want To Skip Starbucks

Look, I get the pull of that drive-thru. But those drinks add up—money-wise and carb-wise. Even the “keto-friendly” ones are usually packed with junk or artificial stuff you don’t want.

Making keto Starbucks drinks at home like this one saves cash, cuts carbs, and lets you control every ingredient. Plus, you get to brag about it on Pinterest, which is half the fun.

One Last Tip

Add a sprinkle of shaved macadamia nuts on top for a crunch. I know it’s an extra step, but it looks cool and gives the drink that tiny nod to real island flavors. If you’ve ever had a mac nut pancake in Hawaii, you’ll get it.

Conclusion

You don’t need to spend $6 a day or load up on carbs just to have coffee that feels special. This Hawaiian Keto Mac Nut Coffee has been a little trick I keep up my sleeve for days when I need to feel a bit more grounded, a bit more put together, and still stay on plan.

It’s one of those low carb coffee recipes that makes it easier to stick with your goals without it feeling like punishment. So go ahead, pour yourself a mug, or chill it over ice and pretend you’re on a beach somewhere. Your taste buds (and your macros) will thank you.
