In a small bowl, whisk together 2 tsp matcha powder and 2 tbsp sugar with 3 tbsp hot water (not boiling, about 160–175°F) until completely smooth and frothy. Jack in the Box technique: Dissolving matcha in hot water ensures no clumps and helps release its natural fragrance.

Add 1.5 cups cold whole milk and 0.25 tsp vanilla extract to a separate pitcher. Stir to combine – this mimics the creamy yet light texture of Jack in the Box’s version.

Personalized Q&A
Q. Does this taste exactly like Jack in the Box's Matcha Iced Latte?
This recipe closely mimics Jack in the Box’s earthy-sweet Matcha Iced Latte by using authentic matcha powder, a hint of vanilla, and careful balancing of milk and sweetness. Whisking matcha with hot water, as in step 1, yields the smooth, clump-free flavor profile signature to their version.
Q. Is this recipe difficult to make at home?
Not at all! With only five easy steps—mainly whisking, mixing, and assembly—this copycat recipe is very beginner-friendly. Active time is under 10 minutes, and no special equipment is needed beyond a whisk and two glasses.
Q. Can I substitute any ingredients in this recipe?
You can swap whole milk for oat, almond, or skim milk depending on your preference. For a less sweet drink, reduce the sugar. If you want a dairy-free version, plant-based milks work well while maintaining creaminess.
Q. How many calories are in this homemade Matcha Iced Latte?
Each glass contains about 180 kcal, with 30g carbs, 6g protein, and 4g fat per serving. That’s a nice balance for a refreshing afternoon boost.
Q. What’s the secret to getting the creamy, layered look like the Jack in the Box original?
Be sure to whisk the matcha until fully dissolved, then layer the matcha mixture over ice before slowly pouring in the milk. This keeps the green matcha distinct until you stir, replicating the eye-catching look of the real Jack in the Box drink.
