1-Creating matcha mochi cookies starts with a few simple steps that lead to soft, flavorful results everyone will enjoy. Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper for easy cleanup. This preparation sets the stage for baking success and ensures your cookies bake evenly.

2-Follow the directions closely to make the mochi and cookie dough. First, stir 80 g glutinous rice flour, 40 g granulated sugar, and 135 mL water in a small bowl. Microwave for 1 minute, then stir; microwave another 1 minute and stir again; finally, microwave for 30 seconds and stir until the mixture becomes very sticky and bouncy. Lightly dust a surface with 2 teaspoons cornstarch, turn the mochi out, pat all sides with cornstarch, and let it cool slightly. Cut into 10 pieces, coating each with cornstarch, and let cool completely.

3-Next, prepare the cookie dough by lining a baking sheet with parchment paper. Whisk 180 g all-purpose flour, 1 tablespoon matcha powder, 1 tablespoon milk powder (if using), ½ teaspoon salt, ½ teaspoon baking soda, and ½ teaspoon baking powder in a medium bowl. Beat 115 g softened unsalted butter until creamy, then add 150 g granulated sugar and beat until fluffy. Mix in 1 large egg and 1 teaspoon vanilla extract. Add the dry mixture to the butter mixture and mix until just combined, leaving some flour patches if needed. Fold in 100 g roughly chopped white chocolate, reserving some for topping, and scoop 4-tablespoon balls of dough onto the baking sheet. Chill for at least 1 hour.

4-To shape and bake, preheat the oven to 350°F if not already done. Create a hole in each chilled dough ball, place a mochi piece inside, wrap the dough around it, and form a ball. Place the balls on the baking sheet with 2 inches of spacing. Bake for 12-14 minutes until the edges are set but the centers remain soft. If desired, press reserved white chocolate pieces on top 1-2 minutes before baking ends. Cool on the baking sheet for 10-15 minutes, then transfer to a wire rack to cool completely.
