Prepare your warm water using a kettle, the microwave, or the stove. You want the water to be warm but not boiling.
Place your matcha sifter over the top of your matcha bowl.
Using a matcha scoop, scoop the matcha powder into the sifter over the bowl. Use the back of the scoop to gently push the matcha powder through the sifter.
Pour the warm water over the top of the sifted matcha in a swirling motion.
Use a bamboo whisk to whisk the matcha and warm water together. You want to make back-and-forth motions with your bamboo whisk (an M or W motion). Whisk the matcha and hot water until no clumps remain, and the matcha is nice and frothy (about 1-2 minutes).
Add ice to your cup or glass, followed by the cane sugar syrup/simple syrup and then the milk.
Pour the whisked matcha over the top, stir with a straw, to combine, then set aside.
In a separate cup, combine the cold foam ingredients: Lavender syrup, 2% milk, and heavy cream, (and optional lavender food coloring.
Froth the mixture together with a handheld milk frother until thick.
Pour the lavender cream cold foam over the iced matcha latte, and enjoy!
