Sift the matcha powder into a small bowl or mug to remove any clumps and ensure a smooth latte.
Add the warmed honey, vanilla extract, and 2 tablespoons of hot water to the matcha powder.
Whisk vigorously in a zigzag motion for 30-45 seconds using a bamboo whisk or milk frother until the mixture forms a smooth, frothy paste with no visible clumps.
Steam or froth your milk to 160-170°F until creamy and foamy. If you don't have a frother, heat the milk gently on the stovetop and whisk vigorously, or shake it in a sealed jar.
Pour the steamed milk into the matcha mixture, stirring gently to combine.
Taste and adjust sweetness if needed, then serve immediately while hot and frothy.
