Whipped Dalgona Vanilla Coffee | The 3-Ingredient Sugar-Free Foam That Tastes Like a Café Drink
I started making dalgona coffee back when everyone was stuck at home whipping instant coffee into clouds. My first few batches were a mess — thin, weepy foam that slid right off the milk. It took me way too long to figure out that the trick isn’t the whipping tool, it’s the ratio. Once I started using equal parts instant coffee, hot water, and sweetener, and whipped it a full two minutes longer than I thought I needed to, the foam finally held its shape like soft-serve. Swapping regular sugar for monk fruit sweetener and pouring it over cold cashew milk instead of dairy turned this into my go-to afternoon drink — low in sugar, dairy-free, and still tastes like a coffee shop treat.
Recipe Highlights
- Minimal Ingredients: Made with just three simple ingredients plus water and ice.

- 100% Dairy-Free: Completely dairy-free thanks to unsweetened cashew milk.
- No Special Equipment: No coffee equipment needed — just instant coffee and a whisk or mixer.
- Quick & No-Cook: Ready in under 10 minutes with no cooking involved.
Key Ingredients Breakdown
Instant Coffee Granules
This is what gives the foam its structure. Instant coffee dissolves fully in hot water and has a protein-like compound structure that lets it whip up into stiff peaks, almost like meringue. Freeze-dried instant coffee works best because it dissolves cleanly. Ground coffee or coffee beans will not whip — you need the instant kind for this to work.
Monk Fruit Sweetener
Monk fruit sweetener does double duty here. It sweetens the foam and helps stabilize it as you whip, similar to how sugar helps egg whites hold their shape. I like a granulated monk fruit blend because it dissolves at the same rate as the coffee. If you don’t have monk fruit sweetener, a granulated erythritol blend or classic white sugar will also whip up fine, though the sugar version won’t be as low in carbs.
Hot Water
Hot water is what activates the whipping process. It needs to be hot enough to fully dissolve both the coffee and the sweetener, but not boiling — boiling water can make the mixture too thin at first and slow down how quickly it thickens.
Unsweetened Cashew Milk
This is the base of the drink and the reason it stays light instead of heavy. Unsweetened cashew milk has a mild, slightly sweet nuttiness without added sugar, so the whipped coffee stays the star of the show. You can swap in almond milk, oat milk, or regular dairy milk if that’s what you have on hand — just keep it unsweetened so the drink doesn’t turn overly sweet.
Vanilla Extract (Optional but Recommended)
A small splash of vanilla extract rounds out the bitterness of the coffee and gives the drink that “café-style” aroma. You can add it straight into the whipped coffee mixture or stir it into the cashew milk — either way works. Vanilla bean paste is a nice substitute if you want little flecks of vanilla in the glass.
Ice
Ice keeps the cashew milk cold and gives the drink its classic iced-coffee texture. Use bigger ice cubes if you can — they melt slower and won’t water down your coffee as fast.
Why You’ll Love This Recipe
A low-sugar, dairy-free whipped coffee treat made easily with cashew milk and monk fruit.
Naturally Lower in Sugar
It’s naturally lower in sugar since monk fruit sweetener replaces regular sugar without leaving a weird aftertaste.
Dairy-Free & Nutty Richness
Cashew milk makes it dairy-free and gives the coffee a light, slightly nutty richness without being heavy.
Simple Ingredients & No Machine
You only need three main ingredients and a whisk or hand mixer — no espresso machine required.
Long-Lasting Foam
The foam holds its shape for a good while, so it still looks pretty even after you’ve taken a few photos.
Easily Scalable
It’s easy to scale up for guests or down for a solo afternoon pick-me-up.
Pro Tips
- Use room-temperature to slightly warm instant coffee — very hot water can sometimes make the foam collapse faster.
- Whip with a hand mixer if you have one. It cuts the whipping time down from around 5 minutes by hand to under 2 minutes.
- Don’t stop whipping too early. The mixture should hold a stiff peak, similar to whipped cream, before you stop.
- Chill your cashew milk and glass ahead of time so the foam doesn’t start melting the moment it hits the glass.
- Add the vanilla extract to the coffee mixture before whipping, not after, so it blends in evenly.
Storage & Reheating
This drink is best enjoyed fresh, right after you stir it together, since the whipped foam will slowly settle and lose its fluffy texture over time. If you need to prep ahead, you can make the whipped coffee mixture up to 2 days in advance and store it in an airtight container in the fridge — just give it a quick re-whip with a fork or whisk before serving, since it will deflate a bit as it sits. I don’t recommend freezing the whipped coffee, since it won’t whip back up properly once thawed. The cashew milk itself can stay chilled in the fridge as usual, following the date on the carton.

kcalThis whipped dalgona vanilla coffee is a two-ingredient foam — instant coffee and monk fruit sweetener — whipped with hot water until it turns thick, glossy, and cloud-like, then spooned over a tall glass of chilled unsweetened cashew milk with ice. It’s smooth, lightly sweet, has a soft coffee bitterness, and looks like something you’d pay six dollars for at a café. Stir it together before you sip, and you’ve got a creamy, low-sugar iced coffee that takes about ten minutes start to finish.

Ingredients
- For the Whipped Coffee:
2 tablespoons instant coffee granules
2 tablespoons monk fruit sweetener (granulated)
2 tablespoons hot water
1/4 teaspoon vanilla extract (optional)
- For the Base:
2 cups unsweetened cashew milk, chilled
1 to 1 1/2 cups ice cubes
Directions
- Combine the whipping ingredients: In a medium mixing bowl, add the instant coffee granules, monk fruit sweetener, hot water, and vanilla extract if using. Make sure the water is hot but not boiling — this helps everything dissolve evenly without thinning the mixture out too much.
- Whip until thick and glossy: Using a hand mixer, milk frother, or a whisk, beat the mixture on medium-high speed. If using a hand mixer, this takes about 1 to 2 minutes. By hand with a whisk, plan on closer to 4 to 5 minutes of steady whisking. You’ll know it’s ready when the mixture turns a light caramel-brown color, looks glossy, and holds a stiff peak when you lift the whisk out.
- Fill your glasses with ice and cashew milk: Grab two tall glasses and fill each about three-quarters full with ice cubes. Pour the chilled unsweetened cashew milk over the ice, leaving a little room at the top for the whipped coffee.
- Spoon the whipped coffee on top: Divide the whipped coffee mixture evenly between the two glasses, spooning it gently on top of the cashew milk so it sits in a fluffy layer instead of sinking in.
- Stir and enjoy: Right before drinking, give it a good stir to combine the whipped coffee with the milk underneath. This is when the drink really comes together — smooth, lightly sweet, and full of coffee flavor in every sip.
Recipe Notes
- A hand mixer or milk frother will save you a lot of arm work compared to whisking by hand.
- Make sure your bowl and beaters are completely dry before you start whipping — any leftover water can mess with how the foam forms.
- If your foam isn’t thickening after several minutes, your water may have been too hot or too cool. Start over with water that’s hot to the touch but not steaming.
- For a stronger coffee flavor, you can use 2½ tablespoons of instant coffee instead of 2, keeping the sweetener the same.
- A tall glass with a wide mouth makes it easier to spoon the whipped coffee in and stir it later.

Frequently Asked Questions
Can I use a different sweetener instead of monk fruit?
Yes. Regular granulated sugar, erythritol blends, or even a granulated stevia blend will all whip up just fine. Keep in mind that liquid sweeteners like honey or maple syrup won’t whip the same way, since the whipping process relies on the sweetener being in granulated form.
Why isn’t my coffee whipping up into foam?
The most common reason is using the wrong type of coffee. This recipe only works with instant coffee granules or crystals, not ground coffee or coffee beans. Also double check that your water is hot enough to fully dissolve the coffee and sweetener before you start whipping — a cold or lukewarm mixture will take much longer to thicken, if it thickens at all.
Can I make this with hot cashew milk instead of iced?
Absolutely. Warm your cashew milk gently on the stove or in the microwave, pour it into a mug, and spoon the whipped coffee on top the same way. It turns into a cozy hot version of the same drink.
