In short: A matcha frappe is matcha blended with ice, milk and a little sweetener into a thick, café-style slush. Whisk 2 g (1 tsp) of matcha into a smooth paste, then blend it with about 120–180 ml of milk, 150–200 g of ice and 1–2 teaspoons of sweetener. It takes about five minutes.
A note on the numbers: The recipe amounts below are a reviewer-confirmed home-kitchen convention, not a measured standard, so treat them as a starting range and adjust to taste. The café figures for calories, sugar and caffeine are Starbucks' own published values for their Matcha Green Tea Frappuccino, which the brand lists as approximate.
How do you make a matcha frappe at home?
You make a matcha frappe by whisking the powder smooth, then blending it with ice, milk and sweetener until it turns to slush. Use 2 g (1 tsp) of matcha, 30–60 ml of water for the paste, 120–180 ml of milk, 150–200 g of ice and 1–2 teaspoons of sweetener. Those are home conventions, so nudge them up for a stronger drink or down for a lighter one.
What you need for a matcha frappe
Everything comes from one shopping list, and you almost certainly have most of it already:
| Ingredient | Amount |
|---|---|
| Matcha | 2 g (1 tsp), up to 4 g (2 tsp) for a stronger drink |
| Water, for the paste | 30–60 ml, warm or cold |
| Milk, dairy or plant | 120–180 ml |
| Ice | 150–200 g, about 1 to 1.5 cups |
| Sweetener or syrup | 1–2 tsp, to taste |
These are reviewer-confirmed conventions for one frappe, not a fixed formula; the recipe makes 1 and scales up cleanly.
Matcha frappe, step by step
- Make a paste. Sift 2 g (1 tsp) of matcha into a cup, add 30–60 ml of water and whisk in a quick zigzag until it is smooth and lump-free. Water around 70–80 °C works well, but for a frappe you can cold-whisk and skip the heat entirely.
- Load the blender. Tip the paste in with 120–180 ml of milk, 150–200 g of ice and 1–2 teaspoons of sweetener.
- Blend to slush. Run it until smooth and thick, stopping to scrape down the sides once or twice. Start to finish is about five minutes; blend to the texture you want, not to the clock.
- Pour and finish. Pour into a tall glass, add whipped cream if you want the café look, and serve straight away. This makes 1 frappe.
The one step people rush is the paste. A fine-pronged bamboo whisk breaks matcha down far smoother than a spoon, which is what keeps the finished frappe from tasting gritty. If you want the proper tool, the Zen matcha tea set pairs a whisk and scoop with the matcha so you can measure the dose by the teaspoon and whisk out every lump.
What's the matcha-to-milk-to-ice ratio?
The workable ratio for one frappe is roughly equal parts milk and ice, with a little more ice for a thicker slush, over a small matcha paste and sweetened to taste — the same reviewer-confirmed amounts as the shopping list above (2 g matcha, 30–60 ml water, 120–180 ml milk, 150–200 g ice, 1–2 tsp sweetener), not measured optimums.
A frappe uses less milk than a latte because the ice supplies most of the volume. More ice makes it thicker and closer to a true frappe; less ice pulls it toward an iced latte. Start with one level teaspoon of matcha and add a second only if you want a bolder, greener drink.
How do you make it taste like the Starbucks Matcha Green Tea Frappuccino?
Match the profile with creamy milk, a little vanilla syrup, plenty of ice and whipped cream on top. The Starbucks Matcha Green Tea Frappuccino is a blended, pre-sweetened cream drink made from green tea powder, vanilla syrup and a frappuccino cream base, blended with milk and ice and finished with whipped cream. There is no coffee or espresso in it, so leave it out of your copycat.
The reason a home version can taste flat at first is that the café drink is sweet and creamy by default. A Grande has about 43 g of sugar. Part of that is milk lactose and the syrups rather than the matcha, so don't pin it all on the tea. The upside of making it yourself is control: you decide how much of that sugar you keep and can dial it down for a lower-sugar frappe.
One thing worth knowing before you shop: ice, milk and sweetener all dilute the matcha, so a flat or dull powder can read muddy-brown in the glass. A vivid-green, premium matcha holds its colour and flavour through the blend, which is what makes a copycat look and taste closer to the café version. More on choosing a grade below.
How do I stop the matcha going lumpy or bitter?
Whisk the matcha into a smooth paste before it goes anywhere near the blender. Sift 2 g (1 tsp) into a cup, add 30–60 ml of water and whisk until glossy and even, with no dry clumps. Pasting first is the single step most recipes skip, and it is why their frappes come out speckled.
Bitterness is usually heat. Use water around 70–80 °C rather than boiling, or cold-whisk the paste for a frappe and avoid the problem altogether. Quality matters too: a fresh, vivid-green matcha tastes clean and sweet, while a dull, yellowish one leans bitter no matter how carefully you whisk it.
How do I make it thicker or creamier?
For a thicker, creamier frappe, add more ice, freeze your milk into cubes, use less water, or blend in a splash of cream, a scoop of ice cream or half a frozen banana. Ice is the main lever: more of it gives you that dense, spoonable slush.
If it comes out too thick to sip, loosen it with a little more milk. If it is too thin, add ice and blend again. There is no single correct texture here, so tune it to whether you want a drink or something closer to a dessert.
Can I make a matcha frappe dairy-free?
Yes. Swap the dairy for any plant milk: oat, almond, soy or coconut all work, with oat the creamiest and almond the lightest. Skip or swap the whipped cream and the whole drink is naturally vegan.
The milk you pick also sets most of the calories. Per cup, oat milk is about 118 kcal and almond about 47, while the matcha itself adds only around 6–7. Coconut and soy vary too much by brand to pin a single figure, so check the carton. A lighter milk and a lighter hand with the syrup is how you beat the café version on calories without losing the drink.
Can I make a matcha frappe without a blender?
You can get close without a blender. Shake the paste, milk and sweetener hard in a sealed jar and pour it over crushed ice, or freeze the milk into cubes and crush them with a milk frother. It won't be quite as smooth as a blended frappe, but it is close.
The trade-off is texture: a blender is what gives you that dense, even slush, so the shake-and-crush method lands a little looser. For most weekday frappes, it is more than good enough.
What grade of matcha should I use for a frappe?
Use a premium-grade matcha: it is the sweet spot for a frappe, vivid green and robust enough to survive ice, milk and sweetener. Matcha runs on a rough scale from culinary, which is bolder and can read dull or bitter, up to ceremonial, which is delicate and made to be sipped with just water.
For a blended, iced, sweetened drink, ceremonial grade is overkill: you pay for a subtlety the ice and syrup drown out. Culinary can taste flat. A premium grade sits in between, keeping a bright colour and clean flavour through the blend, so choose a 100% pure matcha and control the sweetness yourself.
That is exactly where our Premium Grade Matcha Tea Powder is pitched: a single vivid-green matcha that stays green and grassy under ice and milk instead of fading to brown. It is the one we reach for when we make a frappe.
What's the difference between a matcha frappe, a frappuccino, a smoothie and an iced latte?
A frappe is matcha blended with ice into a slush; the ice-blend is what sets it apart. An iced matcha latte is not blended, just matcha poured over ice and milk. A matcha smoothie adds fruit such as banana or berries, so it eats more like a meal. And a Frappuccino is simply Starbucks' branded, trademarked version of a blended frappe.
In short: blending plus ice makes it a frappe, adding fruit makes it a smoothie, skipping the blender makes it an iced latte, and the Starbucks name makes it a Frappuccino.
How much caffeine and how many calories are in a matcha frappe?
A Grande Starbucks matcha frappe has roughly 70 mg of caffeine and about 301 calories. Calories and sugar climb with size:
| Size | Calories | Sugar |
|---|---|---|
| Tall (354 ml) | ~240 kcal | ~26 g |
| Grande (473 ml) | ~301 kcal | ~43 g |
| Venti (591 ml) | ~414 kcal | ~60 g |
Starbucks' published values for the Matcha Green Tea Frappuccino with default milk and whipped cream, listed as approximate. Caffeine runs about 70–100 mg depending on size, and Starbucks lists these as approximate rather than exact.
A home frappe is different on both counts. Its caffeine is set by how much matcha you use: roughly 60–130 mg, worked out from a 2–4 g dose rather than measured in a finished glass, so treat it as an estimate. For the full breakdown, see our guide to caffeine in matcha. Its calories are set by the milk: about 149 (whole), 118 (oat) or 47 (almond) per cup, plus around 6–7 from the matcha. There is more in our matcha calories guide.
On safety, regulators (EFSA) put about 400 mg of caffeine a day as safe for most healthy adults; if you're pregnant, keep it under about 200 mg a day.
Matcha frappe FAQ
What is a matcha frappe made of? Matcha, ice, milk and a little sweetener, blended into a thick slush. You whisk the matcha into a paste first, then blend everything together.
What's the matcha-to-milk-to-ice ratio? For one frappe, use about 2 g (1 tsp) of matcha, 120–180 ml of milk and 150–200 g of ice, sweetened to taste. These are home conventions; see the ratio table above to scale up.
How do I make it taste like the Starbucks matcha frappuccino? The Starbucks drink is pre-sweetened and creamy. Match it with creamy milk, a little vanilla syrup, plenty of ice and whipped cream on top; making it at home lets you match the flavour while controlling the sugar.
Is a matcha frappe healthy, and how much sugar does it have? A Starbucks Grande has about 43 g of sugar, much of it from milk and syrups. Made at home you decide how much sweetener to add, so you control the sugar.
How much caffeine is in a matcha frappe? A home frappe has roughly 60–130 mg, set by your matcha dose and estimated from it rather than measured. A Starbucks Grande has about 70 mg. In pregnancy, keep total caffeine under about 200 mg a day. See caffeine in matcha.
How many calories are in a matcha frappe? A Starbucks Grande is about 301 calories. At home the milk decides it: roughly 149 (whole), 118 (oat) or 47 (almond) per cup, plus about 6–7 from the matcha. See matcha calories.
Can I make it dairy-free or vegan? Yes. Use oat, almond, soy or coconut milk and skip or swap the whipped cream. Per cup, oat is about 118 kcal and almond about 47; coconut and soy vary by brand.
Can I make a matcha frappe without a blender? Yes, though it won't be quite as smooth. Shake the paste, milk and sweetener in a sealed jar and pour over crushed ice, or freeze milk into cubes and crush them with a frother.
What grade of matcha should I use? A premium grade is the sweet spot: vivid green and robust enough to survive ice, milk and sweetener. Ceremonial grade is wasted in a blended, sweetened drink and culinary can read dull, so choose a 100% pure matcha.
