Keto Vietnamese Egg Coffee Recipe: Creamy, Frothy, and So Dang Good

Okay, so this sounds kinda weird at first, right? Egg in coffee?

I thought the same thing too.

But then I tried it… and wow. Vietnamese Egg Coffee (or Cà Phê Trứng if you wanna be fancy about it) is like coffee had a love child with dessert.

Now, traditionally this drink is loaded with sweetened condensed milk. But if you’re rolling with keto life (or just trying to cut the sugar crash), don’t stress, you can totally make a version that’s low-carb, high-fat, and friendly for your macros.

This is one of those drinks that feels way more “luxury café” than “5-minute kitchen experiment”  but honestly, it’s crazy easy to make.

Let me break it down for you like we’re chatting over coffee… fitting, right?

What is Vietnamese Egg Coffee Anyway?

Alright, quick little story. Back in 1940s Hanoi, Vietnam was going through a milk shortage. People still wanted their coffee creamy and sweet, so some genius thought:
“Eh, what if we whipped egg yolk and sugar together and dumped that in coffee?”

Game. Changer.

It’s rich. It’s frothy. It tastes like dessert got lost and ended up in a coffee cup.

Fast forward to today,  and keto people like us? We’re out here remixing the whole thing using low-carb ingredients.

What Does Keto Egg Coffee Taste Like?

Imagine a cross between:

• Tiramisu

• Sweet cream cold foam

• A latte with silky vibes

• Custard… but caffeinated

Honestly, the egg part doesn’t taste eggy at all. It’s more like a creamy cloud sitting on strong, dark coffee.

What You’ll Need (Nothing Fancy, Promise)

Ingredients:

• 1 egg yolk (fresh is best)

• 1 tablespoon heavy cream

• 1 teaspoon powdered erythritol (or any keto-friendly sweetener you like)

• ½ teaspoon vanilla extract (optional, but yum)

• Hot, strong black coffee (espresso works best, but regular brewed is fine too)

That’s it.

No weird stuff. No milk. No syrup bottles cluttering the counter.

Tools You’ll Want

• Hand mixer or milk frother (a whisk works too but arm workout warning)

• Your favorite coffee mug

• Spoon for layering

Optional: A tiny bowl to feel like a professional but totally not required.

How To Make Keto Vietnamese Egg Coffee (Step-By-Step)

Step 1: Brew your coffee

Make it strong, okay? Weak coffee + creamy egg foam = kinda sad.

If you have espresso, perfect. If not, brew like ½ cup of very strong coffee.

Tip: Vietnamese coffee traditionally uses robusta beans, so go for a dark roast if you can.

Step 2: Whip the egg mix

In a bowl, toss in:

• 1 egg yolk

• 1 tbsp heavy cream

• 1 tsp powdered erythritol

• ½ tsp vanilla extract

Now whip it like it owes you money.

Use a hand mixer for about 3-4 minutes until it gets thick, creamy, and turns a little pale in color.

If you’re whisking by hand, bless your soul — it’ll take a little longer, but it works.

Step 3: Pour coffee into your mug

Leave a little room at the top for the foamy magic.

Step 4: Spoon the egg foam on top

This is the fun part.

Gently layer that whipped egg cream over the coffee. Watch it float like a cozy little pillow.

Looks fancy, right?

Step 5: Sip & Stir (Optional)

Some people like to stir it all together. Some like to sip through the foam like a rebel.

Do you.

Why This is Perfect for Keto Life

Alright, let me hit you with some real talk.

Keto gets boring sometimes.

You’ve had your bulletproof coffee. You’ve eaten more eggs than an Easter bunny.

But this? This is like keto-level comfort food… in a cup.

• High fat from egg + cream = stays full longer

• No sugar crash

• Feels like cheating (but it’s not)

• Fancy café vibes at home

What If You’re Weird About Raw Egg?

Totally get it.

But if you’re using fresh eggs and good hygiene, raw yolk in coffee is pretty safe because the hot coffee warms it up slightly.

Still feeling iffy? You can do a quick pasteurization trick:

• Put the egg yolk and cream over a double boiler and whisk for 1-2 minutes until just warm — then whip like normal.

Or just… live dangerously like I do. Your call.

Variations Because Why Not?

Chocolate Keto Egg Coffee

Add ½ tsp cocoa powder to the egg mix for mocha vibes.

Cinnamon Egg Coffee

Sprinkle cinnamon on top like you’re fancy at Starbucks.

Coconut Keto Egg Coffee

Swap heavy cream with coconut cream for a tropical twist.

Protein Boost

Add a little unflavored collagen powder to the coffee — easy protein win.

Thoughts After Making This Way Too Many Times

Okay so truth time: I didn’t want to love this as much as I do.

The first time I made it, I felt like some weird keto scientist in my kitchen. But after one sip? Instant repeat recipe.

And every time I’ve made it for friends, they’ve all said the same thing:

“Wait… this is so much better than I thought.”

Nobody can believe there’s egg in it.

And if you’re already on keto, it’s a game-changer for those mornings where regular black coffee just isn’t hitting right.

Tips If You Wanna Get It Really Good

• Use fresh eggs — don’t skip this. Old eggs taste… well, old.

• Powdered sweetener works way better than granules. No gritty foam, thanks.

• Froth longer than you think. That airy texture is everything.

• Don’t over-sweeten. Let the coffee punch through a little.

Storage? LOL Just Drink It.

This isn’t the kind of drink you make ahead.

It’s one-and-done magic.

The foam will collapse if you leave it sitting for hours. Plus, part of the fun is watching that gorgeous foam sitting pretty on top.

Conclusion: Is It Weird? Yep. Is It Worth It? Absolutely.

Keto Vietnamese Egg Coffee is one of those recipes that makes you feel like you should be paying $9 for it at a cool hidden café.

But instead, you’re standing in your kitchen, probably in sweatpants, living your best low-carb life.

It’s creamy. It’s rich. It feels like a treat but fits right into keto.

Make it once… and good luck going back to boring coffee again.
