Place your coffee grounds in a small bowl. (It's always more fun to use a pretty one.)
Pour a splash of freshly boiled water over your instant coffee and mix with a spoon. Use only as much water as you need to completely dissolve the grains — too much water will make the mask runny.
Add your yogurt to your coffee and mix until creamy.
Drizzle your honey into your mixture. The mask will immediately become runny, but we will fix this in the next step.
Add your matcha and mix well, keeping an eye on the texture. Don't be afraid to add more if the mask is too thin. You want it to stay in place on your face, not end up on your sheets, couch, etc.
If you can handle the swampy smell, more power to you — but if you'd like a more pleasant, spa-like experience, add your essential oils or a splash of vanilla extract. If your choice of fragrance thins the texture of your mask, add a bit more matcha.
