Copycat Starbucks Iced Lavender Cream Oat Milk Matcha
Prep time: 15 min (lavender syrup: 20 min, makes 8–10 servings) Cost at home: about $1.10 per drink vs. about $6.35 at Starbucks Caffeine: ~55mg per Grande (from matcha — no espresso)
The Starbucks Iced Lavender Cream Oat Milk Matcha launched on March 7, 2024, became one of the most photographed drinks on the spring menu, and has returned each spring since — spring 2025, spring 2026. It is a seasonal offering, not a permanent menu item, so the home version has an obvious advantage: you can make it any time of year. And once you know the technique, you can make it for about $1.10 a drink.
One thing to know before you order or make this at home: the cold foam contains heavy cream — this drink is not dairy-free despite the oat milk base. The foam is a standard Starbucks cold foam (heavy cream + oat milk + lavender powder), so it does not fit a dairy-free diet as served. The home version below includes a dairy-free foam option using oat barista blend.
There are two things that trip up home versions: the lavender foam and the matcha base. Most recipes solve one and botch the other.
For the lavender, the mistake is over-steeping. Dried lavender releases its aromatics quickly, and the same compounds that give it a clean floral quality turn soapy when they concentrate. Starbucks sidesteps this with a proprietary lavender powder — a dry blend of lavender flavoring, vanilla, and a base that integrates smoothly into cold foam without tasting chemical or soapy. The home equivalent is a simple syrup steeped for exactly 8 minutes, strained immediately, with vanilla stirred in off heat. That brief, controlled steep and the vanilla balance get you to the Starbucks flavor profile without the soapy edge.
For the matcha, the update matters: in January 2025, Starbucks switched from a pre-sweetened matcha blend to unsweetened matcha powder with classic syrup added separately. If you are following an older copycat recipe that calls for a sweetened matcha blend, your base will taste off. Use unsweetened culinary-grade matcha and add sweetener separately.
The Lavender Simple Syrup
The syrup is the foundation. Make it once and you have enough for 8 to 10 drinks. The active time is about 5 minutes; the rest is waiting.
The rule: steep culinary lavender for no more than 8 minutes, then strain completely and discard the buds before the syrup cools. This is the single most important step. Leaving lavender in the hot syrup as it cools — even 10 more minutes — concentrates the monoterpenes that produce soapiness.
Use dried culinary lavender, not ornamental lavender from a garden center. Culinary cultivars (usually Lavandula angustifolia ‘Vera’ or similar) have a cleaner floral flavor; ornamental hybrids are bred for visual intensity, not for taste, and tend to be more aggressively soapy.
The vanilla extract goes in last, after straining and off heat — not during the simmer, where it would cook off.
The Matcha Base
Bloom the matcha before it ever touches cold liquid. Sifting removes clumps, and whisking it with 175°F water into a paste means every particle is fully dissolved before you add cold oat milk. Cold matcha mixed with cold milk clumps instantly and tastes gritty.
Starbucks uses 2 teaspoons of matcha for a Grande, sweetened with their classic syrup (a 1:1 simple syrup). At home, classic syrup, simple syrup, or even a small amount of honey all work. Start with 1 tablespoon and adjust to taste — the lavender foam adds its own sweetness on top.
The Cold Foam
Cold foam is different from steamed milk foam. It is made from cold (not heated) cream and milk, whipped at high speed until voluminous but still pourable — not whipped cream, not stiff peaks. The goal is a texture that cascades slowly off a spoon, holds its shape briefly, then settles into a thick layer on top of the drink rather than sinking through it.
For this drink: 3 tablespoons heavy cream + 1 tablespoon oat milk + lavender syrup + vanilla, frothed until it doubles in volume and holds soft peaks. The oat milk loosens the cream enough to pour; the cream gives it enough body to float.
The lavender color in Starbucks’ cold foam is a very pale purple-gray from their proprietary powder. The home version, with lavender syrup, will be a cream-white foam with a very subtle lavender tint — not the photogenic purple you see in press images. If you want a deeper lavender color for photos, add one drop of natural purple food coloring or a tiny pinch of butterfly pea powder to the cold foam ingredients before frothing.
Building the Drink
Order matters:
- Ice
- Cold oat milk
- Sweetened matcha paste (poured over a spoon to create the swirling cloud)
- Lavender cold foam (poured gently over a spoon to sit on top)
The spoon-pour technique slows the descent of both the matcha paste and the cold foam, creating a more distinct layering. If you pour directly from the container, both will mix more aggressively into the milk below.
The finished drink: green matcha base, cream-white cold foam on top, with a faint lavender scent when you hold the glass. Stir after photographing, or drink layered — the first sips are foam-forward and creamy, then the earthy matcha hits.
The Cost Math
| Component | Home cost (per drink) | Starbucks (Grande) |
|---|---|---|
| Matcha powder (2 tsp) | ~$0.30 | — |
| Oat milk (3/4 cup) | ~$0.25 | — |
| Lavender syrup (1.5 tsp) | ~$0.15 | — |
| Heavy cream (cold foam) | ~$0.35 | — |
| Vanilla, sugar | ~$0.05 | — |
| Total | ~$1.10 | ~$6.35 |
Six drinks per week at Starbucks costs about $190 a month. Six drinks per week at home costs under $30, including the batch lavender syrup.
