Amai’s Green Tea Sweet

Ingredients
Yield (2” leaf shape): Approx 25

3/4 cup (2.25 oz) Confectioners sugar
5 oz Unsalted butter, cut into cubes
1 3/4 cup (8.5 oz) All-purpose flour
3 Large egg yolks
1.5 TBS Matcha (powdered green tea)
1 cup Granulated sugar (for coating)

Directions

• Preheat the oven to 350F. Line a sheet pan with parchment paper.
• Whisk the confectioner’s sugar and green tea together in a bowl.
• Add the butter and green tea/sugar mixture to the bowl of a stand mixer fitted with the paddle attachment. Mix until smooth and light in color.
• Add the flour and mix until well combined.
• Add the egg yolks and mix just until the eggs are fully incorporated and a mass forms.
• Form the dough into a disk and chill in the refrigerator until firm (about 30 minutes).
• Roll the dough out to ½” thickness.
• Cut the dough with a leaf cookie cutter.
• Toss each cut cookie in a bowl of granulated sugar to coat.
• Place the sugar-coated cookie on a parchment lined pan. Bake at 350F for 12-15 minutes, or until slightly golden around the edges.

Baker’s Note: You can purchase Matcha (powdered green tea) from Asian grocery stores or specialty tea shops. In NYC try McNulty’s Tea House, Ito-En or you can order baking grade matcha online. The higher quality matcha you use, the brighter green the cookies will be. Store the cookies in a tin or other container that blocks out sunlight to preserve the color. The green color will fade when exposed to sunlight.
