What You’ll Need
The magic of this starbucks lavender latte recipe is in the quality of your ingredients. Don’t worry though — everything is easy to find, and I’ll tell you exactly what works best.
The Lavender Base
Culinary lavender and simple syrup are what create that signature floral sweetness. You’ll make your own lavender syrup (it’s easier than you think), which gives you total control over the flavor intensity. I use this brand from Amazon — it makes a huge difference compared to the stuff from the spice aisle that can taste dusty.
If you’re in a pinch, store-bought lavender syrup works, but homemade tastes fresher and lets you adjust the sweetness perfectly.
The Coffee
Fresh espresso or strong coffee forms the backbone of this drink. I use a double shot of espresso (about 2 ounces), but if you don’t have an espresso machine, strongly brewed coffee or even a cold brew concentrate works beautifully.
The key is making sure your coffee is strong enough to stand up to the milk and syrup without getting lost.
The Creamy Element
Oat milk is non-negotiable for this recipe if you want the authentic Starbucks taste. They use Oatly Barista Edition, which froths like a dream and has a naturally creamy, slightly sweet flavor that complements the lavender perfectly. I use this brand from Amazon — it makes a huge difference in texture.
Regular oat milk works too, but barista blends have extra fat and protein that create that silky microfoam.
Optional Finishing Touches
A pinch of vanilla extract and some dried lavender buds for garnish take this from homemade to café-worthy. The vanilla rounds out the floral notes and adds depth, while the lavender buds on top make it Instagram-ready (and let people know what they’re drinking).
🛒 Shopping Tip: Buy culinary-grade lavender, not the decorative kind from craft stores. Culinary lavender is food-safe and has a cleaner, sweeter flavor. You can find it in the tea or spice section, or order it online where it’s usually cheaper.
Pro Tips Before You Start
Here’s what I’ve learned from making this copycat starbucks lavender latte approximately a million times:
- Less is more with lavender — Start with less syrup than you think you need. You can always add more, but you can’t un-lavender a drink that tastes like perfume. I recommend starting with 1-2 tablespoons and adjusting from there.
- Heat your oat milk gently — Oat milk can separate or get slimy if you boil it. Keep it at a gentle simmer (around 150-160°F) and whisk constantly for the best texture.
- Bloom your espresso — Pour the lavender syrup into your hot espresso first and stir. This helps the flavors meld together before the milk hits, creating a more cohesive drink.
- Froth like you mean it — Whether you’re using a frother, French press, or just a jar with a lid, froth your oat milk until it’s doubled in volume and looks like silky foam. This is what separates a good latte from a great one.
- Make your syrup in advance — Lavender syrup keeps for 2-3 weeks in the fridge, so batch it on Sunday and have fancy lattes all week. It’s also amazing in lemonade, by the way.
- Temperature matters for iced versions — If you’re making an iced lavender latte, let your espresso cool for a minute before pouring over ice, or it’ll melt everything and dilute your drink.
- Use a clear glass if you have one — Part of the appeal is seeing those gorgeous layers before you stir. It’s the little things that make homemade drinks feel special.
- Taste as you go — Everyone’s sweetness preference is different. Start with less syrup and add more until it’s perfect for YOUR palate, not mine.
💡 Pro Tip: The single biggest mistake people make is using too much lavender, which creates that “drinking potpourri” effect. If you’re new to floral coffee recipes, start with half the syrup amount and work your way up. Your taste buds will thank you!
How To Make Copycat Starbucks Lavender Oat Milk Latte Recipe
This is genuinely one of the easiest copycat recipes I’ve ever developed. You’re basically making a simple syrup with lavender, pulling some espresso, frothing your oat milk, and assembling everything like the home barista you were meant to be.
The whole process takes about 5 minutes once you have your lavender syrup ready (which itself only takes 10 minutes to make). I promise this is easier than it sounds, and after you make it once, you’ll have the process memorized.
If you love making Starbucks spring drinks at home, this one belongs in your regular rotation alongside favorites like the strawberry blonde espresso and iced matcha latte.

Ingredients
Equipment
Method
-
Brew your espresso shots using an espresso machine or prepare 2 ounces of very strong coffee if you don’t have an espresso maker. The coffee should be hot and freshly brewed with a rich, dark crema on top for the best flavor. Set aside to cool slightly while you prepare the other components.
-
Add the lavender simple syrup and vanilla syrup (if using) to the bottom of your serving glass. Stir the syrups together gently with a spoon to combine them evenly, creating a fragrant base for your latte that will distribute the floral flavor throughout the drink.
-
If making an iced latte, fill your glass with ice cubes until it’s about three-quarters full. The ice should reach near the top of the glass, leaving room for the liquids. For a hot latte, skip this step and use a heat-safe mug instead.
-
Pour the freshly brewed espresso shots directly over the ice and syrup mixture. Watch as the hot espresso begins to melt the ice slightly and blend with the lavender syrup, creating beautiful swirls of color and releasing the aromatic lavender scent.
-
Froth the oat milk using a milk frother, handheld frother, or by shaking vigorously in a sealed jar for 30-45 seconds. The oat milk should become foamy and increase in volume by about one-third, creating a creamy texture with small, velvety bubbles throughout.
-
Slowly pour the frothed oat milk over the espresso and ice, holding back the foam with a spoon initially. Fill the glass almost to the top, allowing the milk to cascade through the coffee and create natural layers of color from dark brown to creamy beige.
-
Spoon the remaining milk foam on top of the latte, creating a thick, cloud-like layer that sits above the liquid. The foam should be dense enough to hold its shape and provide a luxurious mouthfeel with each sip.
-
Garnish with a small pinch of dried culinary lavender buds sprinkled on top of the foam for an authentic Starbucks presentation. Serve immediately with a straw and enjoy the delicate floral notes balanced with the creamy oat milk and bold espresso flavor.

Customizations & Variations
This is where you get to make this starbucks lavender latte dupe truly your own. I’ve tested all of these variations, and they’re all delicious in different ways.
Iced Lavender Latte Version
Fill a tall glass with ice, pour your lavender syrup recipe over the ice, add cold oat milk until the glass is about 3/4 full, then pour your espresso shots over the top. Give it a quick stir and watch those beautiful layers swirl together.
The iced version is actually my favorite during warmer months — it’s incredibly refreshing and the floral notes seem even brighter when cold.
Dairy-Free But Not Oat Milk
While oat milk is the signature choice, almond milk creates a lighter, nuttier version that’s also delicious. Coconut milk adds a tropical twist that surprisingly works with lavender. Just avoid soy milk — it can curdle with the acidity of espresso and doesn’t froth as nicely.
Sugar-Free Lavender Latte
Make your lavender syrup with a sugar substitute like monk fruit sweetener or allulose. The flavor won’t be quite as rich, but it still captures that floral essence beautifully. You can also use fewer lavender buds and add a few drops of liquid stevia directly to the drink.
Brown Sugar Lavender Latte
Swap regular white sugar for brown sugar in your lavender syrup. This creates a deeper, almost caramel-like sweetness that makes the drink feel cozier and more complex. It’s like the oat milk coffee drink version of a warm hug.
Honey Lavender Version
Replace half the simple syrup with honey when making your lavender infusion. This adds a floral-on-floral situation that’s incredibly sophisticated. Use a mild honey so it doesn’t overpower the delicate lavender.
Vanilla Lavender Latte
Add a pump of vanilla syrup or a splash of vanilla extract along with your lavender syrup. This creates a more dessert-like drink that feels extra indulgent. It’s similar to what you might find on the official Starbucks drinks menu during special promotions.
Larger or Smaller Sizes
The recipe makes a standard grande (16 oz). For a tall (12 oz), reduce everything by about 25%. For a venti (20 oz), increase by 25%. The espresso-to-milk ratio should stay roughly the same — adjust the syrup to your sweetness preference.
Lavender Latte With Cold Foam
Top your iced version with sweet cream cold foam for an extra-luxe experience. You can even add a tiny pinch of dried lavender to the foam itself for a gorgeous presentation.
Caffeine-Free Version
Use decaf espresso or swap the coffee entirely for a strong-brewed herbal tea like rooibos or honeybush. You lose the “latte” aspect technically, but you keep that gorgeous lavender-milk combination that’s perfect for evenings.
Lavender Latte Martini
For an adults-only version, add 1-2 ounces of vodka or coffee liqueur to the iced version. It’s like an espresso martini’s prettier, more sophisticated cousin. Shake it with ice and strain into a coupe glass for maximum elegance.
Blended Lavender Frappuccino
Combine all ingredients with ice in a blender for a frozen version that rivals the frappuccino creations on Starbucks’ menu. Add a bit of xanthan gum if you want that signature thick texture.
Rose Lavender Latte
Add a small amount of rose water or rose syrup along with the lavender for a double-floral experience that’s incredibly fragrant and romantic. Use a light hand — a little rose goes a long way.
Storing & Make-Ahead Tips
The beauty of this how to make starbucks lavender latte recipe is that you can prep components ahead and assemble drinks in seconds all week long.
Lavender Syrup Storage
- Refrigerator: Store in an airtight container or bottle for up to 3 weeks. The flavor actually gets better after a day or two as the lavender continues to infuse.
- Freezer: Pour into ice cube trays and freeze for up to 3 months. Pop out a cube whenever you want a latte — each cube equals about 2 tablespoons of syrup.
- Room temperature: Not recommended, as the syrup can develop mold or ferment without refrigeration.
Prepared Latte Storage
- Refrigerator: A fully assembled iced latte keeps for up to 24 hours, though the espresso flavor fades and the milk may separate. Give it a good shake before drinking.
- Hot lattes: Don’t store these — the milk texture breaks down and it just won’t taste good reheated. Make these fresh every time.
Batch Prep Strategy
Here’s my weekly meal prep approach for lavender lattes:
- Make a big batch of lavender syrup on Sunday (it takes 10 minutes and makes enough for 10-12 lattes)
- Store it in a squeeze bottle in the fridge for easy dispensing
- Keep your oat milk and espresso beans stocked
- Each morning, assembly takes literally 3 minutes
What To Keep Separate
Never combine the espresso and milk ahead of time. The coffee becomes bitter and the milk breaks down. Always store your lavender syrup separately and assemble drinks fresh. Think of it like a fancy instant coffee situation — all your components are ready, you just combine them when you want a drink.
✅ Note: If you’re bringing this to work, pack the lavender syrup in a small container, bring your oat milk separately, and grab espresso from your office machine or a local café. Assemble on-site for the freshest taste and you’ll still save money!
Frequently Asked Questions
How many calories are in a homemade lavender oat milk latte?
A 16-ounce homemade version has approximately 180-220 calories depending on how much syrup you use. That’s actually slightly fewer than the Starbucks version, which clocks in around 250 calories for a grande. You can reduce calories further by using less syrup or a sugar substitute.
Can I use regular milk instead of oat milk?
Absolutely! Whole milk creates a richer, creamier latte with a more traditional flavor. 2% milk works great too, though it’s slightly less creamy. The oat milk is signature to the Starbucks version, but any milk you love will work beautifully with the lavender syrup.
How long does lavender syrup last?
Homemade lavender syrup keeps for 2-3 weeks in the refrigerator in an airtight container. You’ll know it’s gone bad if you see any mold, cloudiness, or if it smells off. I’ve never had a batch last that long though — we always use it up first!
Can I make this without an espresso machine?
Yes! Use strongly brewed coffee (double your normal coffee-to-water ratio), a Moka pot, an AeroPress, or even instant espresso powder dissolved in hot water. You can also grab espresso shots from any coffee shop — most will sell them separately for under $2.
Is this healthier than the Starbucks version?
It can be! You control the sugar content, can use organic ingredients, and avoid any preservatives or additives. The homemade version typically has fewer calories and less sugar if you adjust the syrup to taste rather than following a standardized recipe.
Why does my lavender latte taste like soap?
You used too much lavender! This is the most common mistake. Lavender is incredibly potent, and the line between “floral and delicious” and “drinking hand soap” is thinner than you’d think. Start with less lavender in your syrup (about 1 tablespoon per cup of water) and steep for a shorter time.
Can I freeze lavender lattes?
I don’t recommend freezing a prepared latte — the milk and espresso separate and the texture is weird when thawed. However, you CAN freeze the lavender syrup in ice cube trays (genius for iced versions!) or freeze leftover espresso in ice cubes to add to iced lattes without diluting them.
