Original Recipe from Thirstyfortea.com
Makes 20 sandwich cookies.
Ingredients:
- 1 stick unsalted butter, at room temp
- 3/4 cup powdered sugar
- 1/4 cup cornstarch
- 2 Tbsp culinary matcha powder, sifted
- 1/2 tsp vanilla extract
- pinch salt
- 1 box Famous Chocolate Wafers
Equipment:
- mixing bowl
- mesh sieve
- spoon or spatula
- large zip bag
- scissors
Directions:
1. Mix the butter and powdered sugar until light and fluffy. Gradually add the cornstarch, sifted matcha powder, vanilla, and salt until everything is evenly mixed.
2. Transfer the matcha filling into a large zip bag. Snip off a 1/2″ from one corner of the bag. Lay out pairs of cookies, with every other cookie’s rough side facing up. Pipe a blob of frosting, about a 1 1/4″ circle, 1/4″ thick into the center of each cookie with the rough side facing up.
3. Top the frosting blobs with another cookie and apply slow, even pressure so that the filling gets evenly distributed to the edges of the cookies. Store these in airtight containers in the fridge. Serve with milk and enjoy!
