Calorie Count For The Starbucks Lavender Matcha Drink By Size
The iced lavender cream oatmilk matcha landed on Starbucks menus as part of a spring rollout in March 2025. It blends sweetened matcha powder with oatmilk, pumps of Classic syrup, ice, and a thick layer of purple lavender cream cold foam. That build gives it a rich texture and floral-vanilla top, and it also drives the calorie number higher than a basic iced matcha latte.
A tall (12 fl oz) sits around 290 calories, a grande (16 fl oz) is roughly 380 calories, and a venti (24 fl oz) pushes near 470 calories. Carbs and fat climb with size too, since most of the sweetness comes from syrup and pre-sweetened matcha, while the foam carries cream. A grande lands near 20 grams total fat and about 49 grams total carbs, while a venti can reach about 24 grams fat and 61 grams carbs.
| Size | Calories (kcal) | Total Carbs (g) |
|---|---|---|
| Tall 12 fl oz | ~290 | ~35 |
| Grande 16 fl oz | ~380 | ~49 |
| Venti 24 fl oz | ~470 | ~61 |
One grande cup at ~380 calories can take a real bite out of your daily calorie needs. Many people budget a similar number of calories for an entire lunch. No surprise that plenty of shoppers treat this lavender matcha as a dessert drink, not a daily “green tea.”
Why Size Matters
Starbucks pours this lavender matcha in Tall (12 ounces), Grande (16 ounces), and Venti (24 ounces). Each size jump scales the syrup pumps and matcha scoops, not just the ice. The venti is more than “just more liquid;” it is more sugar and more sweet cream foam per sip. That’s why the calorie curve is so steep instead of linear.
The drink arrived alongside other pastel drinks — like an iced lavender oatmilk latte — during a menu refresh where Starbucks dropped slower sellers and pushed playful spring flavors. That spring menu rollout was teased in late February 2025 ahead of March availability in stores, and it leaned hard on colorful, photo-ready cold drinks.
Why The Lavender Matcha Runs High On Calories
Three parts of the cup explain the high number: a sweetened matcha base plus Classic syrup, an oatmilk foundation, and a whipped lavender cold foam lid. Each part adds sweetness, fat, or both.
Sweetened Matcha Base And Classic Syrup
Starbucks matcha powder isn’t plain ceremonial tea powder. The chain uses a sweetened blend. Baristas shake that mix with oatmilk and several pumps of Classic syrup. Those pumps bring fast sugar, which is why a grande sits near 49 grams of total carbs. When you move up to a venti, both syrup and matcha scoops scale up, and carbs jump past 60 grams in one drink.
Lavender Cream Cold Foam On Top
The drink finishes with a layer of lavender cream cold foam. That foam tastes like vanilla sweet cream with a hint of lavender and gives the drink its soft purple cap. Cold foam is made with cream, milk, and flavor syrup spun with air. Cream carries fat, so fat climbs fast: a grande lavender matcha sits near 20 grams of total fat, and a venti can reach about 24 grams. That fat is a big reason the calorie number jumps once you go past a tall cup.
Oatmilk Instead Of Skim Milk
The standard build uses oatmilk, not nonfat dairy milk. Oatmilk pours thicker, brings mild sweetness on its own, and helps the matcha taste round and mellow instead of grassy. Oatmilk also adds starch-driven carbs and a solid calorie base. The creamy mouthfeel people love in this drink comes from both the oatmilk and the lavender foam, so the base and the topper both lean rich.
How This Differs From A Plain Iced Matcha Latte
A plain iced matcha latte at Starbucks (grande with milk and ice, no lavender foam) sits around 190 calories, about 5 grams fat, 27 grams carbs, 25 grams sugar, and roughly 65 milligrams caffeine. Add Classic syrup, swap in oatmilk, and crown the cup with lavender sweet cream, and the lavender version nearly doubles calories to about 380 and bumps fat to roughly 20 grams in the same 16-ounce size.
How To Dial Down Calories And Sugar In Your Lavender Matcha
You can still get the lavender vibe without blowing your calorie target for the day. Starbucks baristas can tweak size, syrup, foam, and milk when you ask. None of these swaps turn it into a “diet drink,” but they nudge calories, fat, and sugar in the direction you want.
Pick A Smaller Cup
Downsizing is the easiest win. Sliding from a grande to a tall trims roughly 90 calories (380 down to about 290) and cuts total carbs from roughly 49 grams to about 35 grams. The tall still gives you the lavender foam cap and the pastel matcha color, just in a smaller pour.
Ask For Fewer Pumps Of Classic Syrup
The Classic syrup layered into the shake is a big sugar source. You can ask the barista for one pump less than standard, or even “no Classic,” and lean on the built-in sweetness from Starbucks matcha powder. Less syrup means fewer fast carbs per sip and a taste that leans more toward earthy matcha and vanilla cream, not straight sweetness.
Ask For Light Lavender Cold Foam
The glossy purple foam on top looks fun in a clear cup, but it also carries much of the fat. You can ask for “light lavender cold foam,” which tells the barista to add a thinner layer. Less foam means less heavy cream, so fat grams drop. This makes the sip taste a bit more like iced matcha latte and a bit less like a whipped dessert topping.
Swap The Milk
The base recipe calls for oatmilk. You can ask for almondmilk instead. Almondmilk at Starbucks pours thinner and tends to carry fewer calories per ounce than oatmilk. The drink won’t taste as bakery-sweet, but you’ll still get the lavender cap and iced green tea body.
Sugar, Fat, And Caffeine In The Lavender Matcha Drink
Sugar: a grande lavender matcha sits near 49 grams of total carbs. Most of that comes from added sugar in the matcha blend, Classic syrup, and sweet cream foam. That’s dessert-level sugar in a 16-ounce cup, closer to a flavored latte than a plain green tea.
Fat: with about 20 grams of total fat in a grande and about 24 grams in a venti, you’re sipping a drink with the same creamy load you’d get from sweet cream cold foam drinks. Much of that fat rides in the lavender foam. That’s why asking for light foam can push calories down fast without losing the lavender look.
Caffeine: Starbucks lists a grande iced matcha latte around 65 milligrams caffeine. A grande cold brew lands around 205 milligrams. You can see this in Starbucks nutrition data for iced matcha latte and in caffeine charts for Starbucks cold brew. Cold brew sits at the high end because it’s brewed long and cold, so it extracts a lot of caffeine. Matcha gives a softer lift.
| Drink Component | What It Adds | Calorie Share In Grande (~380 kcal) |
|---|---|---|
| Sweetened Matcha + Classic Syrup | Sugary base that drives carbs and overall sweetness | ~100+ kcal from fast carbs |
| Oatmilk | Creamy body and mild cereal-sweet flavor | ~150+ kcal from starch and fat |
| Lavender Cream Cold Foam | Whipped vanilla-lavender cap made with cream | ~100+ kcal from heavy cream and syrup |
These buckets aren’t lab-grade math, but they match Starbucks nutrition data. The grande cup lands near 380 calories total, ~20 grams of fat, and close to 49 grams carbs, and the venti jumps to about 470 calories with 61 grams carbs. Those leaps mostly come from scaling oatmilk, syrup, and foam instead of just adding ice.
Should You Sip This Lavender Matcha Every Day?
This lavender matcha tastes like iced matcha latte meets vanilla sweet cream with a soft floral hint. It’s smooth, pastel, and easy to drink for people who want green tea flavor without a strong grassy bite. The flip side: it’s calorie-dense and sugar-heavy for a tea drink, closer to a dessert latte.
If you’re tracking weight goals or blood sugar swings, it helps to treat this cup like a bakery pastry: something you plan in. Pick the tall size, ask for fewer syrup pumps, and ask for light foam to move the drink closer to what you feel good about on a normal weekday. Pair it with protein, like eggs or Greek yogurt at breakfast, or treat it like an afternoon sweet in place of a cookie instead of stacking both.
