Would it work to sub out 2 tsp of matcha powder for flour? I try to avoid food coloring.

LJ, I like your idea. I'll let you know how they turn out!

Thanks so much! I appreciate the suggestions for quantities, since I have not baked with matcha before. Do you both think 2-3 Tbs would be more like it?

Yum, I think that sounds like a great idea—you might need to use a bit more matcha powder to get the color you want though.

Yes, that should work just fine. Though I'm not sure if it'll get that noticeably green with a small amount of matcha in that much dough. You might want to increase it to a couple of tablespoons, unless you're wanting just a very slight green colour and not much matcha flavour.
