Ingredients
Method
Preparation
- Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- In a medium bowl, whisk together the all-purpose flour, cornstarch, and salt until fully combined. Set aside.
- In a large bowl, beat the unsalted butter and powdered sugar on medium speed until light and fluffy, about 2 to 3 minutes.
- Add the egg and vanilla extract to the butter mixture and mix until smooth.
- Gradually add the reserved flour mixture to the butter mixture, stirring until just combined.
Coloring and Assembling
- Divide the dough into three portions: one half for vanilla, one quarter for matcha, and one quarter for strawberry.
- Knead the matcha powder into one portion and the strawberry powder into another until colors are even; leave the largest portion plain.
- Roll the colored doughs into a log about 1½ inches in diameter, pressing gently to seal the edges.
Baking
- Slice the log into 1/4-inch rounds and arrange them on the prepared baking sheet, spacing about 1 inch apart.
- Bake for 10 to 12 minutes, or until edges are set but centers remain soft.
- Let cookies cool on the sheet for 5 minutes before transferring to a wire rack.
Notes
Store in an airtight container for up to a week. For longer storage, freeze uncooked dough for up to three months.
