Can I use regular chocolate chips instead of white chocolate?
Yes, but white chocolate complements matcha's earthy, slightly bitter flavor better. Dark or milk chocolate will shift the taste profile.
How do I make the vanilla cold foam?
Whip heavy cream, vanilla extract, and a touch of sugar with an electric mixer or frother until stiff peaks form, then top the iced latte.
How much matcha powder should I use in the latte?
The recipe specifies 1 tbsp matcha for the cookies; whisk 1–2 tsp matcha powder per serving of latte, adjusting to taste.
Can I make the cookies ahead and store them?
Yes, bake and cool completely, then store in an airtight container for up to 5 days. Reheat briefly before serving with the latte for best texture.
What matcha powder grade should I buy?
Culinary-grade matcha works fine for cookies; ceremonial-grade is pricier but nicer for the latte if you want a smoother, less bitter taste.
