This Lavender Mint Iced Latte Tastes Like a Cafe Treat, But It’s Sugar-Free
I started playing with lavender in coffee after a trip to a tiny cafe that put a single dried bud on top of my cold brew. I was skeptical — lavender can turn soapy fast if you use too much. After a few messy batches in my own kitchen, I found the trick: steep the lavender with fresh mint together, and use just a pinch. The mint keeps the lavender from tasting like a candle, and the two together make something that tastes closer to a spring garden than a perfume counter. This latte is my warm-weather favorite, and it’s sugar-free without losing any of that syrupy iced-coffee feel.
Recipe Highlights
- Real Lavender Flavor: Naturally floral flavor from real dried lavender buds, not lavender extract.
- Perfectly Balanced: Fresh mint balances the lavender so it never tastes soapy.
- Zero Refined Sugar: Sweetened entirely with erythritol — no refined sugar.
- Quick Preparation: Ready in under 10 minutes, mostly hands-off.
- Diet & Caffein Friendly: Easily made dairy-free or fully caffeine-free.
Key Ingredients Breakdown
Dried Culinary Lavender
This is the star flavor. Make sure you buy lavender labeled “culinary,” since regular decorative lavender can carry stronger, more perfume-like oils. A little goes a long way here — the lavender infuses into a simple syrup rather than going straight into your coffee, which gives you more control over the strength. If you can’t find culinary lavender, food-grade dried lavender from a spice shop works the same way.
Fresh Mint Leaves
Mint is what keeps this drink tasting bright instead of heavy. It cuts through the floral notes of the lavender and adds a cool, herbal freshness that makes the latte taste alive. Spearmint is my go-to because it’s gentler, but peppermint works too if you want a sharper, more cooling flavor. Dried mint can stand in if fresh isn’t available, though you’ll want to use less since dried herbs are more concentrated.
Erythritol
Erythritol sweetens the syrup without any of the blood sugar spike of regular sugar, and it dissolves nicely into warm liquid. I like it here because it doesn’t leave a strong aftertaste the way some other sugar substitutes do. If you don’t have erythritol, a monk fruit blend or allulose will both sweeten similarly. Regular sugar or honey can be used too if you’re not looking to keep this sugar-free.
Strong Brewed Coffee or Espresso
This is your coffee base, and it needs to be strong since it will be poured over ice, which dilutes flavor. Cold brew concentrate, double-shot espresso, or coffee brewed extra strong all work well. If you want a lighter caffeine hit, half-caff coffee is a fine swap, and for a caffeine-free version, strongly brewed rooibos tea makes a lovely floral base on its own.
Milk of Choice
Milk gives the latte its creamy body and softens the coffee’s bitterness. Whole milk makes it richest, but oat milk and almond milk both froth up nicely and pair well with the floral notes. Coconut milk adds a slightly tropical twist if you don’t mind that flavor coming through.
Why You Will Love This Recipe
A sugar-free, cafe-style lavender-mint latte that can be enjoyed hot or iced.
Sugar-Free & Rich
It’s sugar-free but still tastes rich and syrupy, thanks to erythritol.
Quick 5-Minute Pot Syrup
The lavender-mint syrup comes together in one small pot in under 5 minutes.
Great for Meal Prep
You can make a big batch of syrup and keep it in the fridge for a week of lattes.
Affordable Cafe Style
It looks like something from a fancy cafe menu but costs pennies to make at home.
Hot or Iced Versatility
It works hot or iced, so you get two drinks out of one recipe.
Pro Tips
- Strain the syrup through a fine mesh sieve so no lavender buds or mint bits end up in your glass.
- Make a double batch of syrup — it keeps in the fridge for up to a week and speeds up busy mornings.
- Use ice cubes made from leftover coffee so your latte doesn’t get watered down as they melt.
- Add the syrup to your coffee before the milk so the flavors blend evenly.
- Taste your syrup before straining and adjust sweetness while it’s still warm, since it’s easier to dissolve erythritol at that stage.
Storage & Reheating
Store the lavender mint syrup in an airtight jar in the fridge for up to 1 week — it’s the only part of this recipe that needs storing, since the latte itself is best enjoyed fresh. If you have leftover assembled latte, keep it covered in the fridge for up to a day, though the ice will melt and dilute it a bit. There’s no need to reheat this drink since it’s meant to be served cold, but if you’d like it warm, gently heat the coffee and milk together on the stove and stir in the syrup at the end.

Ingredients
- For the Lavender Mint Syrup:
1 cup water
1/2 cup erythritol
1 tablespoon dried culinary lavender buds
1/4 cup fresh mint leaves, loosely packed (plus extra for garnish)
- For the Latte:
1 cup strong brewed coffee or 2 shots espresso, cooled
1 cup milk of choice
Ice cubes
Fresh mint sprig, for garnish (optional)
Directions
- In a small saucepan, combine the water and erythritol over medium heat. Stir gently for about 2 minutes, just until the erythritol fully dissolves into the water and the mixture looks clear rather than cloudy.
- Remove the pan from the heat and stir in the dried lavender buds and fresh mint leaves. Let the mixture steep for 10 to 15 minutes at room temperature — the longer it sits, the stronger the floral flavor will be, so taste it partway through if you prefer a lighter touch.
- Pour the syrup through a fine mesh strainer into a clean jar, pressing gently on the lavender and mint to release any last bit of flavor. Discard the solids and let the syrup cool completely, or pop it in the fridge for 10 minutes to speed things up.
- Fill two tall glasses with ice cubes. Pour about 2 tablespoons of the lavender mint syrup into each glass, adjusting to taste depending on how sweet and floral you like your latte.
- Pour the cooled coffee over the ice, splitting it evenly between the two glasses, then top each glass with 1/2 cup of milk.
- Stir well to combine everything and blend the syrup evenly through the drink. Garnish with a fresh mint sprig and a few dried lavender buds if you want that cafe-style finish, then serve right away.
Recipe Notes
- A fine mesh strainer or cheesecloth is needed to keep lavender buds out of your final drink.
- Start with a smaller amount of lavender if it’s your first time using it — you can always steep longer next time for a stronger flavor.
- A milk frother or small whisk can help you get a creamier, more cafe-style texture on top.
- If your syrup turns cloudy or grainy, your erythritol likely didn’t fully dissolve — reheat gently and stir again before adding the herbs.

Frequently Asked Questions
Can I use dried mint instead of fresh?
Yes, though dried mint is more concentrated, so use about half the amount called for. Fresh mint gives a brighter, more cooling flavor, so I recommend it if you can find it.
Why does my lavender taste soapy or bitter?
This usually happens when too much lavender is used or it steeps too long. Stick to 1 tablespoon for this batch size, steep for no more than 15 minutes, and always pair it with mint to balance the floral notes.
Can I make this recipe caffeine-free?
Absolutely. Swap the coffee for strongly brewed rooibos tea, which has a naturally sweet, earthy flavor that pairs beautifully with the lavender and mint.
Is erythritol safe to use in cold drinks?
Yes, but erythritol dissolves best in warm liquid, which is why this recipe has you make it into a syrup first rather than adding it directly to the cold latte.
